🧊 Playing with boxes​

In this tutorial, you'll learn to easily create the bounding boxes of a BIM model. This can be useful for knowing the overall position and dimension of your models, which can be used, for instance, to make the camera fit a whole BIM model in the screen.

Bounding boxes?

Bounding boxes (AABB or Axis-Aligned Bounding Boxes) are the boxes aligned with the X, Y and Z axes of a 3D model that contain one or many objects. They are very common in 3D applications to make fast computations that require to know the whole dimension or position of one or many objects.

In this tutorial, we will import:

  • @thatopen/components to set up the barebone of our app.
  • Stats.js (optional) to measure the performance of our app.
  • @thatopen/ui to add some simple and cool UI menus.
import Stats from "stats.js";
import * as BUI from "@thatopen/ui";
import * as OBC from "@thatopen/components";

🌎 Setting up a simple scene​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial.

const container = document.getElementById("container")!;

const components = new OBC.Components();

const worlds = components.get(OBC.Worlds);

const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

world.camera.controls.setLookAt(12, 6, 8, 0, 0, -10);

world.scene.setup();

const grids = components.get(OBC.Grids);
grids.create(world);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🧳 Loading a BIM model​

We'll start by adding a BIM model to our scene. That model is already converted to fragments, so it will load much faster than if we loaded the IFC file.

Fragments?

If you are not familiar with fragments, check out the IfcLoader tutorial!

const fragments = components.get(OBC.FragmentsManager);
const file = await fetch(
  "https://thatopen.github.io/engine_components/resources/small.frag",
);
const data = await file.arrayBuffer();
const buffer = new Uint8Array(data);
const model = fragments.load(buffer);
world.scene.three.add(model);

world.camera.controls.setLookAt(12, 6, 8, 0, 0, -10);

world.scene.setup();

const grids = components.get(OBC.Grids);
grids.create(world);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

);
const data = await file.arrayBuffer();
const buffer = new Uint8Array(data);
const model = fragments.load(buffer);
world.scene.three.add(model);

🎲 Creation of Bounding Boxes​

Now that our setup is done, lets see how you can create the bounding boxes of the model. BIM models are complex, but don't worry: creating the bounding boxes is a piece of cake thanks to the BoundingBoxer.💪 -We can add models to the computation of the bounding box simply by using the add() method.

const fragmentBbox = components.get(OBC.BoundingBoxer);
fragmentBbox.add(model);

👓 Reading the Bounding Box data​

After adding the model, we can now read the mesh from bounding box using getMesh() method.

Don't forget to clean up after using it! 🧹

It's a good practice to reset the bounding box after using it with the reset() method. Otherwise, if you add more models or meshes to the bounding boxer, the bounding box will compute a bounding box that includes everything (including the previously added models).

const bbox = fragmentBbox.getMesh();
fragmentBbox.reset();

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Now we will create a new panel with an input to make the camera fit the model to the screen. For more information about the UI library, you can check the specific documentation for it!

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel active label="Bounding Boxes Tutorial" class="options-menu">
      <bim-panel-section collapsed label="Controls">
         
        <bim-button 
          label="Fit BIM model" 
          @click="${() => {
            world.camera.controls.fitToSphere(bbox, true);
          }}">  
        </bim-button>  

      </bim-panel-section>
    </bim-panel>
    `;
});

document.body.append(panel);

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
      <bim-button class="phone-menu-toggler" icon="solar:settings-bold"
        @click="${() => {
          if (panel.classList.contains("options-menu-visible")) {
            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }
        }}">
      </bim-button>
    `;
});

document.body.append(button);

Classifier

🔴🔵 Classifying your BIM models​

In this tutorial, you'll learn how to classify your BIM models by different criterias, how to get the list of items that belong to a specific category and how to change their color.

Why classifications?

Classifications are a powerful way to organize your BIM models. They allow you to group them according to different parameters. For example: getting all the walls, or all the items that belong to a specific floor or room.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • web-ifc to get some IFC items.
  • @thatopen/ui to add some simple and cool UI menus.
  • @thatopen/components to set up the barebone of our app.
  • Stats.js (optional) to measure the performance of our app.
import Stats from "stats.js";
import * as THREE from "three";
import * as BUI from "@thatopen/ui";
import * as WEBIFC from "web-ifc";
import * as OBC from "@thatopen/components";

🌎 Setting up a simple scene​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial.

const container = document.getElementById("container")!;
const components = new OBC.Components();
const worlds = components.get(OBC.Worlds);

const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

world.camera.controls.setLookAt(12, 6, 8, 0, 0, -10);

world.scene.setup();

const grids = components.get(OBC.Grids);
grids.create(world);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🧳 Loading a BIM model​

We'll start by adding a BIM model to our scene. That model is already converted to fragments, so it will load much faster than if we loaded the IFC file.

Fragments?

If you are not familiar with fragments, check out the IfcLoader tutorial!

const fragments = new OBC.FragmentsManager(components);
const file = await fetch("https://thatopen.github.io/engine_components/resources/small.frag");
const data = await file.arrayBuffer();
const buffer = new Uint8Array(data);
const model = fragments.load(buffer);
world.scene.three.add(model);

🗃️ Classifiying the BIM model​

Next, we will set up a classifier that will help us identify the objects in the scene by their classification (e.g. their spatial structure or their category). Although you can instantiate the classifier by hand, we will use components.get() to get the classifier. All components are meant to be singletons by Components instance, and this method will make sure that this is the case.

const classifier = components.get(OBC.Classifier);

Now we can classify the BIM model. The classifier includes 3 methods:

  • byEntity: classifies the model by IFC category.
  • byIfcrel: classifies the model by an indirect relationship. In this case, we'll classify the model by its spatial structure (project, site, storey an space).
  • byModel: classifies the model by model. This might seem redundant, but it's useful if you have multiple BIM models in the same scene and want to quickly select all the objects of one of them.
classifier.byEntity(model);
classifier.byIfcRel(model, WEBIFC.IFCRELCONTAINEDINSPATIALSTRUCTURE, "storeys");
classifier.byModel(model.uuid, model);

Now, to get the fragments set that belong to a certain classification, we can use the find() method. This method allows us to pass an object with filters. For example, to get all items of category "IFCWALLSTANDARDCASE", we can do: 

const walls = classifier.find({
  entities: ["IFCWALLSTANDARDCASE"],
});

Now, let's do that some more times. We'll gather some objects by category to later control its color from a fancy UI that we will build:

const slabs = classifier.find({
  entities: ["IFCSLAB"],
});

const curtainWalls = classifier.find({
  entities: ["IFCMEMBER", "IFCPLATE"],
});

const furniture = classifier.find({
  entities: ["IFCFURNISHINGELEMENT"],
});

const doors = classifier.find({
  entities: ["IFCDOOR"],
});

const all = classifier.find({
  models: [model.uuid],
});

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Now we will add some UI to control the color of the classified elements fetched above. We'll also add a button to reset the color of all items to the original state. For more information about the UI library, you can check the specific documentation for it!

const color = new THREE.Color();

const panel = BUI.Component.create<BUI.PanelSection>(() => {

🎉 Wrap up​

That's it! You have classified the items of a BIM model by IFC Category, by spatial structure and by model. You can now use the classifier to quickly access the items of one or many BIM models by specific filters.

Clipper

Source

Copying and pasting? We've got you covered! You can find the full source code of this tutorial here.

✂️ Cutting our scene with planes​

The Clipping Tool is a powerful feature in 3D modelling that helps you dissect 3D objects. Clipping Tool is useful for inspecting and analyzing objects in detail.💪

Clipping?

Clipping is the process of "cutting" a 3D object by creating a plane. That way, we can have a bird view of the inside of a BIM model.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • @thatopen/ui to add some simple and cool UI menus.
  • Stats.js (optional) to measure the performance of our app.
import * as THREE from "three";
import Stats from "stats.js";
import * as BUI from "@thatopen/ui";
import * as OBC from "@thatopen/components";

🌎 Setting up a simple scene​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial.

const container = document.getElementById("container")!;

const components = new OBC.Components();

const worlds = components.get(OBC.Worlds);
const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

world.camera.controls.setLookAt(10, 10, 10, 0, 0, 0);

world.scene.setup();

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🎲 Creating a Cube Mesh​

Let's start by adding a Cube, which we can dissect. We will create a Cube with 3x3x3 dimensions and use purple color for the material.

const cubeGeometry = new THREE.BoxGeometry(3, 3, 3);
const cubeMaterial = new THREE.MeshStandardMaterial({ color: "#6528D7" });
const cube = new THREE.Mesh(cubeGeometry, cubeMaterial);
cube.position.set(0, 1.5, 0);
world.scene.three.add(cube);
world.meshes.add(cube);

⚡ Initializing the Raycaster​

We also need to initialize the Raycaster for this world so that the position of the mouse is tracked from the very first moment we use the clipping planes.

const casters = components.get(OBC.Raycasters);
casters.get(world);

⚙️ Adding the Clipper​

Here comes the interesting part, we will add a Simple Clipper to our scene. You can instantiate it, but it's always better to use the components.get(OBC.Clipper) method to get it. All components are meant to be used as a singleton per components instance, and using this system to get a component makes sure this happens.

const clipper = components.get(OBC.Clipper);
Controllign the plane

Each plane generated by the clipper can be controlled using the built-in 3D arrows. You can control the activation and visibility of each plane using plane.enabled and plane.visible. To control the activation and visibility of all planes, use clipper.enabled and clipper.visible.

clipper.enabled = true;

🤝 Performing Clipping Events​

Now, we want a way to create a clipping plane on demand. You can do it with a Single Click or Double Click of a mouse. For this tutorial, we will use Double Click. This will cast a ray from the mouse position to the scene and check if the ray intersects with any of the 3D objects. If it does, it will create a new clipping plane in the point of intersection.

container.ondblclick = () => clipper.create(world);

We use the Raycaster to determine if the intersection has occurred. The clipper places a plane after detecting the face on which the mouse was clicked. 😎 -:::

🧹 Deleting the Clipping Planes​

Now that we know how to make multiple clipping planes, we must also know how to delete them when necessary. Clipping planes can be removed using clipper.delete(world) (which will pick the first plane under the mouse using the raycaster in the specified world) or clipper.delete(world, plane) (which will delete a specific clipping plane).

window.onkeydown = (event) => {
  if (event.code === "Delete" || event.code === "Backspace") {
    clipper.delete(world);
  }
};
Delete all the Clipping Planes

❎ If you want to safely delete all the clipping planes that were created you can simply call clipper.deleteAll().

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";

world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Now we will create some UI elements and bind them to some of the controls of the clipper, like activation, visibility, size, color, etc. For more information about the UI library, you can check the specific documentation for it!

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`

          @change="${({ target }: { target: BUI.Checkbox }) => {

            clipper.size = target.value;
          }}">
        </bim-number-input>
        
        <bim-button 
          label="Delete all" 
          @click="${() => {
            clipper.deleteAll();

});

document.body.append(panel);

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`

            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }

✂️ Cutting our scene with planes​

The Clipping Tool is a powerful feature in 3D modelling that helps you dissect 3D objects. Clipping Tool is useful for inspecting and analyzing objects in detail.💪

Clipping?

Clipping is the process of "cutting" a 3D object by creating a plane. That way, we can have a bird view of the inside of a BIM model.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • @thatopen/ui to add some simple and cool UI menus.
  • Stats.js (optional) to measure the performance of our app.
import * as THREE from "three";
import Stats from "stats.js";
import * as BUI from "@thatopen/ui";
import * as OBC from "@thatopen/components";

🌎 Setting up a simple scene​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial.

const container = document.getElementById("container")!;

const components = new OBC.Components();

const worlds = components.get(OBC.Worlds);
const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

world.camera.controls.setLookAt(10, 10, 10, 0, 0, 0);

world.scene.setup();

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🎲 Creating a Cube Mesh​

Let's start by adding a Cube, which we can dissect. We will create a Cube with 3x3x3 dimensions and use purple color for the material.

const cubeGeometry = new THREE.BoxGeometry(3, 3, 3);
const cubeMaterial = new THREE.MeshStandardMaterial({ color: "#6528D7" });
const cube = new THREE.Mesh(cubeGeometry, cubeMaterial);
cube.position.set(0, 1.5, 0);
world.scene.three.add(cube);
world.meshes.add(cube);

⚡ Initializing the Raycaster​

We also need to initialize the Raycaster for this world so that the position of the mouse is tracked from the very first moment we use the clipping planes.

const casters = components.get(OBC.Raycasters);
casters.get(world);

⚙️ Adding the Clipper​

Here comes the interesting part, we will add a Simple Clipper to our scene. You can instantiate it, but it's always better to use the components.get(OBC.Clipper) method to get it. All components are meant to be used as a singleton per components instance, and using this system to get a component makes sure this happens.

const clipper = components.get(OBC.Clipper);
Controllign the plane

Each plane generated by the clipper can be controlled using the built-in 3D arrows. You can control the activation and visibility of each plane using plane.enabled and plane.visible. To control the activation and visibility of all planes, use clipper.enabled and clipper.visible.

clipper.enabled = true;

🤝 Performing Clipping Events​

Now, we want a way to create a clipping plane on demand. You can do it with a Single Click or Double Click of a mouse. For this tutorial, we will use Double Click. This will cast a ray from the mouse position to the scene and check if the ray intersects with any of the 3D objects. If it does, it will create a new clipping plane in the point of intersection.

container.ondblclick = () => clipper.create(world);

We use the Raycaster to determine if the intersection has occurred. The clipper places a plane after detecting the face on which the mouse was clicked. 😎 +:::

🧹 Deleting the Clipping Planes​

Now that we know how to make multiple clipping planes, we must also know how to delete them when necessary. Clipping planes can be removed using clipper.delete(world) (which will pick the first plane under the mouse using the raycaster in the specified world) or clipper.delete(world, plane) (which will delete a specific clipping plane).

window.onkeydown = (event) => {
  if (event.code === "Delete" || event.code === "Backspace") {
    clipper.delete(world);
  }
};
Delete all the Clipping Planes

❎ If you want to safely delete all the clipping planes that were created you can simply call clipper.deleteAll().

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Now we will create some UI elements and bind them to some of the controls of the clipper, like activation, visibility, size, color, etc. For more information about the UI library, you can check the specific documentation for it!

});

🚅 Managing Performance​

There are occasions when your scene has too many objects. Multiple objects being rendered simultaneously lengthens computation time⌛️ and degrades performance.🌡️ In this tutorial, we will use ScreenCuller to improve performance by reducing unnecessary computations.🚀

What's "culling"?

Culling is a process where we hide some objects of the scene. In this case, we'll hide objects that are not visible, either because they are outside of the scope of the camera, or because there are other objects in front of them, hiding them from the camera. The goal is simple: only compute the objects visible by the camera. This is great in BIM models, because we generally don't want to see ALL the objects at the same time.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • Stats.js (optional) to measure the performance of our app.
import * as THREE from "three";
import Stats from "stats.js";
import * as OBC from "../..";

🌎 Setting up a simple scene​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial.

const container = document.getElementById("container")!;

const components = new OBC.Components();

const worlds = components.get(OBC.Worlds);
const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

world.camera.controls.setLookAt(13, 13, 13, 0, 0, 0);

world.scene.setup();

const grids = components.get(OBC.Grids);
grids.create(world);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🧰 Creating Screen Culler​

Although adding Screen Culler to your project can appear difficult, it is actually very easy. We just need to get the Cullers component and create a new instance of ScreenCuller. Remember that although you can instance the Cullers component, it's better to get it from the components object, as all the components are meant to be singletons within a Component instance, and this ensures that.

const cullers = components.get(OBC.Cullers);
const culler = cullers.create(world);

You can use the threshold property to control the minimum size of an element in screen in order for it to be revealed by the culler. Higher numbers result in less objects visible, but more performance:

culler.threshold = 200;

Additionally, we will activate the culler.renderDebugFrame so that we can see the 2D screen of the elements that are not occluded. We will get the domElement and attach it to the body so that we can see this frame in real-time. To see it in your app, just comment out the debugFrame.style.visibility = "collapse"; line.

culler.renderDebugFrame = true;
const debugFrame = culler.renderer.domElement;
document.body.appendChild(debugFrame);
debugFrame.style.position = "fixed";
debugFrame.style.left = "0";
debugFrame.style.bottom = "0";
debugFrame.style.visibility = "collapse";

🧱 Adding a ton of cubes​

We'll add the Simple 3D Cube and do it 300 times!🤯 We'll generate box geometry and use Lambert material.

const cubes: THREE.Mesh[] = [];
const geometry = new THREE.BoxGeometry(2, 2, 2);
const material = new THREE.MeshLambertMaterial({ color: "#6528D7" });
Randomising the Cubes Placement

We'll write a quick utility function that returns a random number between 0 and the specified upper limit. You can use this for a variety of purposes, but for this tutorial it will be used to generate random positions for cubes that we will add later to our scene.📌

function getRandomNumber(limit: number) {
  return Math.random() * limit;
}

Now, using the getRandomNumber() method we previously created, we will add the 300 cube meshes to our scene at random positions. We'll add the cube to the scene and adjust its position between 0 and 10. +

We'll add the cube to the scene and adjust its position between 0 and 10. Additionally, we will add meshes to the culler object, which will help the culler recognize and draw the elements that are visible to the camera, which can be done with the culler's add() method.

function regenerateCubes() {
  for (let i = 0; i < 300; i++) {
    const cube = new THREE.Mesh(geometry, material);
    cube.position.x = getRandomNumber(10);
    cube.position.y = getRandomNumber(10);
    cube.position.z = getRandomNumber(10);
    cube.updateMatrix();
    world.scene.three.add(cube);
    culler.add(cube);
    cubes.push(cube);
  }
}

regenerateCubes();

🔄️ Updating the Culler​

Here comes the most crucial part! The core aim of ScreenCuller is to output just those components that are visible to the camera.

How often should you update the culler?

It depends on the experience you are looking for. Naturally, the most often you update it, the faster your user will discover new objects that were hidden before, but that also means that your app will be less performant.

In this tutorial we are updating it each time the camera stops moving, which generally works well for most apps.

culler.needsUpdate = true;
world.camera.controls.addEventListener("controlend", () => {
  culler.needsUpdate = true;
});

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

Great job! 🎉 Now you know how to optimise your 3D scene using a -Screen Culler component! Your BIM app will now have unmatched performance and can render huge scenes easily.

🧨 Exploding BIM models​

Sometimes we want to explode our BIM model by level, allowing us to see what's inside like if it was a toy. In this tutorial, we'll learn to do it.

Exploding, like bombs?

Nope! Exploding means offsetting the items of each floor a fixed distance. The effect makes the model look like it's "opened up", like a doll house. This effect is very interesting to have a bird view of both the inside and the outside of a BIM model.

In this tutorial, we will import:

  • web-ifc to get some IFC items.
  • @thatopen/ui to add some simple and cool UI menus.
  • @thatopen/components to set up the barebone of our app.
  • Stats.js (optional) to measure the performance of our app.

  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

world.camera.controls.setLookAt(12, 6, 8, 0, 0, -10);

world.scene.setup();

const grids = components.get(OBC.Grids);
grids.create(world);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🧳 Loading a BIM model​

We'll start by adding a BIM model to our scene. That model is already converted to fragments, so it will load much faster than if we loaded the IFC file.

Fragments?

If you are not familiar with fragments, check out the IfcLoader tutorial!

const fragments = new OBC.FragmentsManager(components);
const file = await fetch(
  "https://thatopen.github.io/engine_components/resources/small.frag",
);
const data = await file.arrayBuffer();
const buffer = new Uint8Array(data);
const model = fragments.load(buffer);
world.scene.three.add(model);

const properties = await fetch("https://thatopen.github.io/engine_components/resources/small.json");
model.setLocalProperties(await properties.json());

🤯 Boom!​

Exploding BIM models is very simple with components. The Exploder component does all the heavy lifting for us! We can get it using the get method of the components instance we are using in this app.

const exploder = components.get(OBC.Exploder);

Before being able to use it, we will need to get the classifier to classify the items of the model by storey.

Classify?

If you are not familiar with the classifier, check out its specific tutorial!

const classifier = components.get(OBC.Classifier);
classifier.byIfcRel(model, WEBIFC.IFCRELCONTAINEDINSPATIALSTRUCTURE, "storeys");

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Now we will add some UI to explode and restore our BIM model, which can be easily done with a checkbox that determines whether a model is exploded or not. For more information about the UI library, you can check the specific documentation for it!

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel active label="Exploder Tutorial" class="options-menu">
      <bim-panel-section collapsed label="Controls">
        <bim-checkbox 
          label="Explode model" 
          @change="${({ target }: { target: BUI.Checkbox }) => {
            exploder.set(target.value);
          }}">  
        </bim-checkbox>  

      </bim-panel-section>
    </bim-panel>
    `;
});

document.body.append(panel);

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
      <bim-button class="phone-menu-toggler" icon="solar:settings-bold"
        @click="${() => {
          if (panel.classList.contains("options-menu-visible")) {
            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }
        }}">
      </bim-button>
    `;
});

document.body.append(button);

🎉 Wrap up​

That's it! You have created an app that can explode and restore a BIM model, allowing to have an overview of both the inside and the outside of a BIM model!

🧶 Managing Fragment Efficiently​

Until recently, we had been adding 3D objects to the Scene with the traditional scene.add API. -We will now use Fragment to work with large BIM models.🏗️ -Fragment are faster and easier to use Geometric API, which reduces draw calls and speeds up the processing of 3D objects. -In this tutorial, we will load and render .frag files using Fragment Manager.

First, let's set up a simple scene!

👀 If you haven't started there, check out that tutorial first!

🧭 Fragment Powerhouse​

Let's begin by including Fragment Manager, -which requires the parameter component to be provided to it. -In terms of capabilities, Fragment Manager is a true powerhouse.🏭

const fragments = new OBC.FragmentsManager(components);

🧩 Add Fragment To Scene​

Using a single API, a Fragment can be quickly added to the scene. -Everything else is taken care of by fragment.load, which makes it easier to render a Fragment file.💪💪

let uuid: string = "";

async function loadFragments() {
  if (fragments.groups.size) {
    return;
  }
  const file = await fetch("https://thatopen.github.io/engine_components/resources/small.frag");
  const data = await file.arrayBuffer();
  const buffer = new Uint8Array(data);
  const group = fragments.load(buffer);
  world.scene.three.add(group);
  uuid = group.uuid;
  console.log(group);
}
Loading IFC files as Fragment

You're probably wondering how IFC files can be loaded as Fragment. -The same approach can be used to load an IFC file with a fragment; -view its own tutorial for further information.

📤 Storing Fragment​

Fragment Manager provides us with option to export the Fragment we have used in our Scene. -Fragment are exported to Blob, -which can be used to generate a File and then download it.↗️ -Let's see how you can use fragment.export in your code.

function download(file: File) {
  const link = document.createElement("a");
  link.href = URL.createObjectURL(file);
  link.download = file.name;
  document.body.appendChild(link);
  link.click();
  link.remove();
}

function exportFragments() {
  if (!fragments.groups.size) {
    return;
  }
  const group = fragments.groups.get(uuid);
  if (!group) {
    return;
  }
  const data = fragments.export(group);
  const blob = new Blob([data]);
  const file = new File([blob], "small.frag");
  download(file);
}
Creating Dynamic URLs

URL.createObjectURL() comes handy when you want to generate a URL for files that were generated programmatically. -You can read more about it here.

🧹 Discard Fragment and Clean the Scene​

At some point, you will require to render numerous Fragment and discard them when not needed. -You can use dispose() method which will remove the Fragment Meshes from the Scene.✂️ -After using fragments.dispose(), you should reinitialize Fragment Manager to maintain it's original state for further uses.

function disposeFragments() {
  fragments.dispose();
}

Loading a .zip fragment that you have locally is also quite easy:

function importExternalFragment() {
  if (fragments.groups.size) {
    return;
  }
  const input = document.createElement("input");
  input.type = "file";
  input.onchange = async () => {
    if (!(input.files && input.files[0])) return;
    const file = input.files[0];
    if (file.name.includes(".frag")) {
      const url = URL.createObjectURL(file);
      const result = await fetch(url);
      const data = await result.arrayBuffer();
      const buffer = new Uint8Array(data);
      fragments.load(buffer);
    }
    input.remove();
  };
  input.click();
}

const gui = new dat.GUI();

const actions = {
  loadFragments: () => loadFragments(),
  disposeFragments: () => disposeFragments(),
  exportFragments: () => exportFragments(),
  importExternalFragment: () => importExternalFragment(),
};

gui.add(actions, "loadFragments").name("Load Fragments");
gui.add(actions, "disposeFragments").name("Dispose Fragments");
gui.add(actions, "exportFragments").name("Export Fragments");
gui.add(actions, "importExternalFragment").name("Import External Fragment");

Congratulations 🎉 on completing this short yet powerful tutorial! -Now you can render or export Fragment files in your BIM Apps using Fragment Manager 🎯 -Let's keep it up and check out another tutorial! 🎓

🚀 Handling BIM models like a boss​

In this tutorial, you'll learn how to load your BIM models in Fragment format. Fragment is an open source geometry system that we created on top of Three.js to display BIM models fast, while keeping control over the individual items of the model. The idea is simple: a BIM model is a FragmentsGroup, which is (like the name implies) a collection of fragments. A fragment is a set of identical geometries instantiated around the scene.

How do I get a BIM model in Fragment format?

The IfcLoader component does exactly that! It converts IFC models to Fragments. Check out that tutorial if you are starting out with IFC files. Of course, you can just use the IfcLoader in your app, but loading fragments is more than x10 faster than loading IFC files. Our recommendation is to convert your IFC files to fragments just once, store the fragment somewhere (frontent of backend) and then load the fragments instead of teh IFC models directly.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/ui to add some simple and cool UI menus.
  • @thatopen/components to set up the barebone of our app.
  • Stats.js (optional) to measure the performance of our app.
import * as THREE from "three";
import Stats from "stats.js";
import * as OBC from "@thatopen/components";
import * as BUI from "@thatopen/ui";

🌎 Setting up a simple scene​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial.

const container = document.getElementById("container")!;

const components = new OBC.Components();

const worlds = components.get(OBC.Worlds);

const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

world.camera.controls.setLookAt(12, 6, 8, 0, 0, -10);

world.scene.setup();

const grids = components.get(OBC.Grids);
grids.create(world);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🧶 Loading a fragments model​

Let's begin by getting the FragmentsManager, which is the component to load, export, get and dispose Fragments in your app.🏭

const fragments = components.get(OBC.FragmentsManager);

Now we can load a fragment from a file. We will fetch the model data and use the load method of the FragmentsManager to get the fragment object. Then, we'll add it to the scene of the current world. We will also create an UUID of the model to later get it somewhere else.

let uuid = "";

async function loadFragments() {
  if (fragments.groups.size) {
    return;
  }
  const file = await fetch(
    "https://thatopen.github.io/engine_components/resources/small.frag",
  );
  const data = await file.arrayBuffer();
  const buffer = new Uint8Array(data);
  const group = fragments.load(buffer);
  world.scene.three.add(group);
  uuid = group.uuid;
}

📤 Storing Fragments​

Let's see how you can export fragments as a file. First, we'll define a function to download a file:

function download(file: File) {
  const link = document.createElement("a");
  link.href = URL.createObjectURL(file);
  link.download = file.name;
  document.body.appendChild(link);
  link.click();
  link.remove();
}

Fragments Manager can export fragments using the export method. The method takes the UUID of a fragment as an argument and returns a Blob, which can be used to generate a File and then download it using the function defined just before.↗️

function exportFragments() {
  if (!fragments.groups.size) {
    return;
  }
  const group = fragments.groups.get(uuid);
  if (!group) {
    return;
  }
  const data = fragments.export(group);
  const blob = new Blob([data]);
  const file = new File([blob], "small.frag");
  download(file);
}

🧹 Discard Fragment and Clean the Scene​

When your user "closes" one or many BIM models, you'll need to discard that FragmetsGroup. You can dispose a specific FragmentsGroup using the disposeGroup method, or dispose all FragmentsGroups using the dispose method.

function disposeFragments() {
  fragments.dispose();
}

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Now we will create a simple panel with a set of buttons that call the previously defined functions. For more information about the UI library, you can check the specific documentation for it!

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel active label="Fragments Manager Tutorial" class="options-menu">
      <bim-panel-section collapsed label="Controls">
      
        <bim-button 
          label="Load fragments" 
          @click="${() => {
            loadFragments();
          }}">
        </bim-button>
        
        <bim-button 
          label="Dispose fragments" 
          @click="${() => {
            disposeFragments();
          }}">
        </bim-button>
        
        <bim-button 
          label="Export fragments" 
          @click="${() => {
            exportFragments();
          }}">
        </bim-button>
        
      </bim-panel-section>
    </bim-panel>
    `;
});

document.body.append(panel);

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
      <bim-button class="phone-menu-toggler" icon="solar:settings-bold"
        @click="${() => {
          if (panel.classList.contains("options-menu-visible")) {
            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }
        }}">
      </bim-button>
    `;
});

document.body.append(button);

🎉 Wrap up​

That's it! Now you know how to load, export and dispose Fragments in your app. Fragments are much faster than raw IFC models, so you should definitely store them in your app if you want your users to have a fast loading experience. For bigger models you can use streaming, but that's another tutorial!

🕸️ Adding a fancy grid to our scene​

In this tutorial you'll learn how to add a fancy grid to your scene. It's super easy and will make your app look much more professional!

Why a grid?

Grids are very common in 3D apps, and it's a great way to have a reference point for your users to navigate around, even when there are no visible objects around.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
import * as THREE from "three";
import * as OBC from "@thatopen/components";

world.scene.three.add(cube);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🕷️ Adding the grid to the world​

To add the grid to the world, we will use the Grids component. Instead of instantiating it, we will get it directly from the components object. Remember that all components are meant to be singletons. Then, we will call the create method to add a grid to the scene.

const grids = components.get(OBC.Grids);

Many times, we just want to look at a specific part of a BIM model, without seeing the rest of it. BIM models are complex, and finding what we are looking for is not always easy. Luckily, the components library has tools to make it easier!

  • @thatopen/ui to add some simple and cool UI menus.
  • web-ifc to get some IFC items.
  • @thatopen/components to set up the barebone of our app.
  • Stats.js (optional) to measure the performance of our app.

grids.create(world);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🔎 Custom filters for your BIM models​

First, let's start by creating a FragmentManager instance and loading a simple fragment. If you haven't checked out the tutorial -for that component yet, do it before going forward!

const fragments = new OBC.FragmentsManager(components);
const file = await fetch("https://thatopen.github.io/engine_components/resources/small.frag");
const data = await file.arrayBuffer();
const buffer = new Uint8Array(data);
const model = fragments.load(buffer);
world.scene.three.add(model);

Now that we have our model, let's start the FragmentHider. You +for that component yet, do it before going forward!

const fragments = components.get(OBC.FragmentsManager);
const file = await fetch(
  "https://thatopen.github.io/engine_components/resources/small.frag",
);
const data = await file.arrayBuffer();
const buffer = new Uint8Array(data);
const model = fragments.load(buffer);
world.scene.three.add(model);

const properties = await fetch(
  "https://thatopen.github.io/engine_components/resources/small.json",
);
model.setLocalProperties(await properties.json());

const indexer = components.get(OBC.IfcRelationsIndexer);
const relationsFile = await fetch(
  "https://thatopen.github.io/engine_components/resources/small-relations.json",
);
const relations = indexer.getRelationsMapFromJSON(await relationsFile.text());
indexer.setRelationMap(model, relations);

Now that we have our model, let's start the FragmentHider. You can use the loadCached method if you had used it before: it will automatically load all the filters you created in previous sessions, -even after closing the browser and opening it again:

const hider = new OBC.FragmentHider(components);

📕📗📘 Setting up simple filters​

Next, we will classify data by category and by level using the -FragmentClassifier. This will allow us to create a simple -filter for both classifications. Don't worry: we'll get to -the more complex filters later!

const classifier = new OBC.Classifier(components);
classifier.byStorey(model);
classifier.byEntity(model);

Next, we will create a simple object that we will use as the -base for the floors filter. It will just be a JS object with -the name of each storey as key and a boolean (true/false) as -value:

const storeys: Record<string, any> = {};
const storeyNames = Object.keys(classifier.list.storeys);
for (const name of storeyNames) {
  storeys[name] = true;
}

Now, let's do the same for categories:

const classes: Record<string, any> = {};
const classNames = Object.keys(classifier.list.entities);
for (const name of classNames) {
  classes[name] = true;
}

Finally, we will set up a simple menu to control -the visibility of storeys:

BUI.Manager.init();

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel active label="Hider Tutorial" 
      style="position: fixed; top: 5px; right: 5px">
      
      <bim-panel-section fixed name="Floors" style="padding-top: 10px;">
      </bim-panel-section>
      
      <bim-panel-section fixed name="Categories" style="padding-top: 10px;">
      </bim-panel-section>
      
    </bim-panel>
  `;
});

document.body.append(panel);

const floorSection = panel.querySelector(
  "bim-panel-section[name='Floors']",
) as BUI.PanelSection;

const categorySection = panel.querySelector(
  "bim-panel-section[name='Categories']",
) as BUI.PanelSection;

for (const name in storeys) {
  const panel = BUI.Component.create<BUI.Checkbox>(() => {
    return BUI.html`
      <bim-checkbox checked label="${name}"
        @change="${({ target }: { target: BUI.Checkbox }) => {
          const found = classifier.find({ storeys: [name] });
          hider.set(target.value, found);
        }}">
      </bim-checkbox>
    `;
  });
  floorSection.append(panel);
}

for (const name in classes) {
  const checkbox = BUI.Component.create<BUI.Checkbox>(() => {
    return BUI.html`
      <bim-checkbox checked label="${name}"
        @change="${({ target }: { target: BUI.Checkbox }) => {
          const found = classifier.find({ entities: [name] });
          hider.set(target.value, found);
        }}">
      </bim-checkbox>
    `;
  });
  categorySection.append(checkbox);
}

That's it! That button will open a floating menu that will allow -you to create custom multi-filters that work even for custom -property sets and quantity sets, including logical operators. -Try them out in the example below, and check out more tutorials -to bring your BIM apps to the next level!

- - +even after closing the browser and opening it again:

const hider = components.get(OBC.Hider);

📕📗📘 Setting up simple filters​

Next, we will classify data by category and by level using the Classifier. This will allow us to create a simple filter for both classifications.

const classifier = components.get(OBC.Classifier);
classifier.byEntity(model);
await classifier.bySpatialStructure(model);

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Next, we will create a simple object that we will use as the base for the floors filter. It will just be an object with the name of each storey as key and a boolean (true/false) as value:

const spatialStructures: Record<string, any> = {};
const structureNames = Object.keys(classifier.list.spatialStructures);
for (const name of structureNames) {
  spatialStructures[name] = true;
}

Now, let's do the same for categories:

const classes: Record<string, any> = {};
const classNames = Object.keys(classifier.list.entities);
for (const name of classNames) {
  classes[name] = true;
}

Now we will add some UI to control the visibility of items per category and per floor using simple checkboxes. For more information about the UI library, you can check the specific documentation for it!

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel active label="Hider Tutorial" class="options-menu">
      <bim-panel-section collapsed label="Controls">
      
      <bim-panel-section collapsed name="Floors"">
      </bim-panel-section>
      
      <bim-panel-section collapsed name="Categories"">
      </bim-panel-section>
      
    </bim-panel>
  `;
});

document.body.append(panel);

const floorSection = panel.querySelector(
  "bim-panel-section[name='Floors']",
) as BUI.PanelSection;

const categorySection = panel.querySelector(
  "bim-panel-section[name='Categories']",
) as BUI.PanelSection;

for (const name in spatialStructures) {
  const panel = BUI.Component.create<BUI.Checkbox>(() => {
    return BUI.html`
      <bim-checkbox checked label="${name}"
        @change="${({ target }: { target: BUI.Checkbox }) => {
          const found = classifier.find({ spatialStructures: [name] });
          hider.set(target.value, found);
        }}">
      </bim-checkbox>
    `;
  });
  floorSection.append(panel);
}

for (const name in classes) {
  const checkbox = BUI.Component.create<BUI.Checkbox>(() => {
    return BUI.html`
      <bim-checkbox checked label="${name}"
        @change="${({ target }: { target: BUI.Checkbox }) => {
          const found = classifier.find({ entities: [name] });
          hider.set(target.value, found);
        }}">
      </bim-checkbox>
    `;
  });
  categorySection.append(checkbox);
}

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
      <bim-button class="phone-menu-toggler" icon="solar:settings-bold"
        @click="${() => {
          if (panel.classList.contains("options-menu-visible")) {
            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }
        }}">
      </bim-button>
    `;
});

document.body.append(button);

🎉 Wrap up​

That's it! You have created an app with an UI that allows the user to control the visibility of items in a BIM model by floor and by category. Well done!

💪 Let's go BIG​

Do you need to open huge big IFC files fast, even on more modest devices? If so, you are in luck! We can open virtually any model on any device in seconds thanks to BIM TILES!

BIM tiles?

The idea behind BIM tiles is pretty simple! Instead of loading the whole BIM model at once, we just load the explicit geometries that are seen by the user. It's way faster than opening the IFC directly, but for this you'll need a backend (or to rely on the file system of the user if you are building a desktop or mobile app).

Let's see how to do this step by step!

🧩 Converting the IFC model to tiles​

The first step is to transform the IFC model into BIM tiles. The reason why we have to do this is pretty simple: geometry in IFC is implicit (e.g. a wall is defined as an extrusion). This means that it needs to be computed and converted to explicit geometry (triangles) so that it can be displayed in 3D.

note

As you know, IFC files contains two things: geometries and properties. We need to convert both things if we want to take full advantage of streaming!

The way the streaming works is by fetching files based on the visible things in the viewer. Those files contain pieces of geometry information (geometry chunks) that the engine uses in order to create and display the geometry. But, where do we get those files from? Easy! From the IFC conversion to tiles. So, let's start converting the IFC geometry to tiles and getting those files so the streamer can do its job. In order to do it, we need the first component from the collection of streaming components: FragmentIfcStreamConverter:

// We need this wasm configuration later to convert properties
const wasm = {
  path: "https://unpkg.com/web-ifc@0.0.53/",
  absolute: true,
};

const tiler = new OBC.IfcGeometryTiler(components);
tiler.settings.wasm = wasm;
tiler.settings.minGeometrySize = 20;
tiler.settings.minAssetsSize = 1000;

The FragmentIfcStreamConverter class takes IFC files and transform their geometry into tiles.

danger

The converter doesn't give you the files needed to streaming right away, just the data that must be contained in those files. Is your job to create the files! Why? Because then you can have full control over when, where and how to create them.

The first file we need is a JSON which is the entry point of the geometries streaming. That JSON must have the following structure:

// @ts-ignore
interface GeometriesStreaming {
  assets: {
    id: number;
    geometries: {
      color: number[];
      geometryID: number;
      transformation: number[];
    }[];
  }[];

  geometries: {
    [id: number]: {
      boundingBox: { [id: number]: number };
      hasHoles: boolean;
      geometryFile: "url-to-geometry-file-in-your-backend";
    };
  };

  globalDataFileId: "url-to-fragments-group-file-in-your-backend";
}

The second file is actually not just a single file, but X number of files (depends on how big is your model) that contains the required information to generate the geometry while streaming. +

      geometryFile: "url-to-geometry-file-in-your-backend";
    };
  };

  globalDataFileId: "url-to-fragments-group-file-in-your-backend";
}

The second file is actually not just a single file, but X number of files (depends on how big is your model) that contains the required information to generate the geometry while streaming. In order to create the JSON file and get the information with the geometry, the FragmentIfcStreamConverter as well as other components in the collection of streaming components, emits events that let you get the processed data from the conversion process.

info

Nedless to say, you need to set up your event listeners before triggering the conversion!

Let's start with the first event:

let files: { name: string; bits: (Uint8Array | string)[] }[] = [];

let geometriesData: OBC.StreamedGeometries = {};
let geometryFilesCount = 1;

tiler.onGeometryStreamed.add((geometry) => {
  const { buffer, data } = geometry;
  const bufferFileName = `small.ifc-processed-geometries-${geometryFilesCount}`;
  for (const expressID in data) {
    const value = data[expressID];
    value.geometryFile = bufferFileName;
    geometriesData[expressID] = value;
  }
  files.push({ name: bufferFileName, bits: [buffer] });
  geometryFilesCount++;
});

One of the most important things to keep in mind is that the event we just setup will get fired as many times as per the "chunk" data generated by the converted. Simply put, the event will get fired several times ⏲ and per each time we will produce one file data that is stored in the geometryFiles array. Later on, we will download the geometry files ⏬.

note

As you see, geometriesData is not being stored as a file to be downloaded. The reason is because that is part of the information we need to create the entry JSON file 🚀.

Nice! Let's go with the second event that will give us more information to create the required files:

let assetsData: OBC.StreamedAsset[] = [];

tiler.onAssetStreamed.add((assets) => {
  assetsData = [...assetsData, ...assets];
});

This one is easier as the event doesn't produce binary data, but information we need to create the JSON file.

Are you familiar with That Open Engine?

If you're familiar with That Open Engine, you should recall fragments. Fragments are just a fancy word we use to refer to ThreeJS geometry efficiently created from IFC files which are the things you end up see in the viewer... one IFC file is usually composed of many fragments and all of them are grouped in a FragmentsGroup, which is the final processed IFC model.

Why do we remind you about FragmentsGroup? Because streaming also works with them! So yes, when you convert an IFC to tiles, the converter also creates a FragmentsGroup in the background, and that information is extremely important for the streamer in order to display the streamed file as everything gets grouped there. So, there is another event that gives you the FragmentsGroup binary data and we also need to create a file with that information.

tiler.onIfcLoaded.add((groupBuffer) => {
  files.push({
    name: "small.ifc-processed-global",
    bits: [groupBuffer],
  });
});
danger

You can name the file whatever you want, but is extremely important you finish the file name with -global!

This is pretty much it! Now that we've setup the main listeners, the last thing is to download all the data once the conversion has fininshed. To do so, we can use the progress event:

function downloadFile(name: string, ...bits: (Uint8Array | string)[]) {
  const file = new File(bits, name);
  const anchor = document.createElement("a");
  const url = URL.createObjectURL(file);
  anchor.href = url;
  anchor.download = file.name;
  anchor.click();
  URL.revokeObjectURL(url);
}

async function downloadFilesSequentially(
  fileList: { name: string; bits: (Uint8Array | string)[] }[],
) {
  for (const { name, bits } of fileList) {
    downloadFile(name, ...bits);
    await new Promise((resolve) => {
      setTimeout(resolve, 100);
    });
  }
}

tiler.onProgress.add((progress) => {
  if (progress !== 1) return;
  setTimeout(async () => {
    const processedData = {
      geometries: geometriesData,
      assets: assetsData,
      globalDataFileId: "small.ifc-processed-global",
    };
    files.push({
      name: "small.ifc-processed.json",
      bits: [JSON.stringify(processedData)],
    });
    await downloadFilesSequentially(files);
    assetsData = [];
    geometriesData = {};
    files = [];
    geometryFilesCount = 1;
  });
});

Great! Now that we have everything setup, is time to finally convert the IFC file. In order to trigger the conversion, we can just do the following:

async function processFile() {
  const fetchedIfc = await fetch("https://thatopen.github.io/engine_components/resources/small.ifc");
  const ifcBuffer = await fetchedIfc.arrayBuffer();
  // We will need this information later to also convert the properties
  const ifcArrayBuffer = new Uint8Array(ifcBuffer);
  // This triggers the conversion, so the listeners start to be called
  await tiler.streamFromBuffer(ifcArrayBuffer);
}

If everything went as expected, you should now be seeing some files being downloaded from your app 🤯 Do not get scary if they're a lot, as big models tend to have many files! All of that is the information the streaming uses in order to display the geometry in the most efficient way possible 💪

Getting entity relations the easy way 💪​

If you're aware of the IFC schema, you should know that all the possible information an entity have is not directly inside its attributes. For example, the property sets, classifications, materials, etc, of a wall (or any other element) are not directly in the wall attributes 🤯 but in other entities which are related to the wall using relations. Now, that is perfect for an schema like the IFC which aims to store all the building data within a single text file in the easiest way possible. However, is not that easy to work just because you need to find the relations you want to get to the element data you're looking for 😪. Luckily for you, the IfcRelationsIndexer already gives you an easy way to get the entities which are related with your elements thanks to the inverse attributes! 🔥🔥

Loading a model 🏦​

First things first, lets load an IFC model to process its relations.

tip

If you're unsure on the details to load a model, just tool at the IfcLoader tutorial!

const ifcLoader = components.get(OBC.IfcLoader);
await ifcLoader.setup();
const file = await fetch("/resources/small.ifc");
const buffer = await file.arrayBuffer();
const typedArray = new Uint8Array(buffer);
const model = await ifcLoader.load(typedArray);
world.scene.three.add(model);

Once the model is loaded in memory, you just need to get an instance of the IfcRelationsIndexer and process the model... it's as easy as that! 😎

const indexer = components.get(OBC.IfcRelationsIndexer);
await indexer.process(model);

The result of that is basically a map where the keys are the expressIDs and the values are other expressIDs related to the first one and grouped by the type of relation. You don't need to worry too much about the details of that, as the usage is pretty straighforward 🔝. The only thing that matters is you've now an easy way to access the entities related to your element 🙂

Getting element psets 📄​

One of the most important relations between different entities is the IfcRelDefinesByProperties. That relation links together an arbitrary entity with a set of IfcPropertySet entities that applies properties. Getting them with the IfcRelationsIndexer once the model is indexed is pretty easy:

const psets = indexer.getEntityRelations(model, 6518, "IsDefinedBy");
if (psets) {
  for (const expressID of psets) {
    // You can get the pset attributes like this
    const pset = await model.getProperties(expressID);
    console.log(pset);
    // You can get the pset props like this or iterate over pset.HasProperties yourself
    await OBC.IfcPropertiesUtils.getPsetProps(
      model,
      expressID,
      async (propExpressID) => {
        const prop = await model.getProperties(propExpressID);
        console.log(prop);
      },
    );
  }
}
tip

IsDefinedBy is the inverse attribute name in the IFC Schema that holds the relations with property sets 😉

Awesome! really easy right?

Exporting the indexation​

In bigger models, the process to calculate the relations index may take some time. The important thing is that there is no reason to calculate over and over the relations index every time you load a model. If the model hasn't change, their properties shouldn't neither! So, let's download the relations index to load it later.

const downloadJSON = (json: string, name: string) => {
  const file = new File([json], name);
  const a = document.createElement("a");
  a.href = URL.createObjectURL(file);
  a.download = file.name;
  a.click();
  URL.revokeObjectURL(a.href);
};

const json = indexer.serializeModelRelations(model);
console.log(json);
tip

As @thatopen/components can be used in either NodeJS and Browser environments, the logic to generate a JSON file may vary!

Now, in case you've loaded several models and want to get all the computed relations, there is also a handy method to do it.

const allRelationsJSON = indexer.serializeAllRelations();

Loading back the relations index​

What do we gain with having a pre-processed relations index if we can't use it again, right? Well, let's use the downloaded relations index 😎

// Lets first delete the existing model relations
delete indexer.relationMaps[model.uuid];
const relationsIndexFile = await fetch("/resources/small-relations.json");
const relationsIndex = indexer.getRelationsMapFromJSON(
  await relationsIndexFile.text(),
);
indexer.setRelationMap(model, relationsIndex);

Great! Now try to get again the property sets and you will see everything working nice and neat. In fact, lets try to get the building storey of one element in the IFC 👇

const buildingStorey = indexer.getEntityRelations(
  model,
  6518,
  "ContainedInStructure",
);

if (buildingStorey && buildingStorey[0]) {
  const storey = await model.getProperties(buildingStorey[0]);
  console.log(storey);
}
tip

Despite there are some relations that corresponds to only one element (e.g., an element can only have one associated building storey) the getEntityRelations will always return an array. That's the reason we take the first buildingStorey relation despite it will always be the only one.

Congratulations! Now you know how to get an easy way to get the relations of your model. Keep going with more tutorials! 💪

MiniMap

Source

Copying and pasting? We've got you covered! You can find the full source code of this tutorial here.

🗺️ Orientating your user in the scene​

In this tutorial you'll learn how to use the Minimap, which is a small 2D representation of the 3D world.

Do you mean a floorplans?

Not quite. The minimap is a simple 2D representation of the 3D world. It is useful to help your user understand where they are, and to have a simple top view of their surrounding.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • @thatopen/ui to add some simple and cool UI menus.
  • Stats.js (optional) to measure the performance of our app.
import Stats from "stats.js";
import * as BUI from "@thatopen/ui";
import * as THREE from "three";
import * as OBC from "@thatopen/components";

🌎 Setting up a simple scene​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial.

const container = document.getElementById("container")!;

const components = new OBC.Components();

const worlds = components.get(OBC.Worlds);
const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

world.scene.setup();

components.init();

const grids = components.get(OBC.Grids);
grids.create(world);

world.camera.controls.setLookAt(1, 2, -2, -2, 0, -5);

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🏠 Loading a model​

Now that we have a scene, let's load a model. We will use the Fragment Manager for it.

Showing Fragments in the Scene

🏔️ There is a dedicated tutorial on how to use Fragment Manager to load IFC files, check it out if you haven't already!

const fragments = new OBC.FragmentsManager(components);

const file = await fetch(
  "https://thatopen.github.io/engine_components/resources/small.frag",
);
const dataBlob = await file.arrayBuffer();
const buffer = new Uint8Array(dataBlob);
const model = fragments.load(buffer);
world.scene.three.add(model);

🗺 Setting up the map​

Now, that we have our setup ready. Let's start with the exciting stuff. -We will use MiniMap component, which does all the work for us.🔮

const maps = new OBC.MiniMaps(components);
const map = maps.create(world);

We have already created a simple DIV element with id minimap in our HTML file. We need to fetch it to add the canvas where our minimap is rendered to it. We'll also add a rounded border to make it look better.

const mapContainer = document.getElementById("minimap") as HTMLDivElement;
const canvas = map.renderer.domElement;
canvas.style.borderRadius = "12px";
mapContainer.append(canvas);
map.resize();

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

we'll also need a reference to the size of the minimap to control it:

const mapSize = map.getSize();

Now we will create a new panel with some inputs to control the different parameters of the MiniMap, like zoom, size and front offset. For more information about the UI library, you can check the specific documentation for it!

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel label="Minimap Tutorial" class="options-menu">
      <bim-panel-section collapsed label="Controls">
      
        <bim-checkbox checked="true" label="Enabled" 
          @change="${({ target }: { target: BUI.Checkbox }) => {
            map.enabled = target.value;
          }}">  
        </bim-checkbox>
        
        <bim-checkbox checked label="Lock rotation" 
          @change="${({ target }: { target: BUI.Checkbox }) => {
            map.lockRotation = target.value;
          }}">  
        </bim-checkbox>
      
        <bim-color-input 
          label="Background Color" color="#202932" 
          @input="${({ target }: { target: BUI.ColorInput }) => {
            world.scene.three.background = new THREE.Color(target.color);
          }}">
        </bim-color-input>
        
        
        <bim-number-input 
          slider label="Zoom" value="${map.zoom}" min="0.01" max="0.5" step="0.01" 
          @change="${({ target }: { target: BUI.NumberInput }) => {
            map.zoom = target.value;
          }}">
        </bim-number-input>
        
        <bim-number-input 
          slider label="Front offset" value="${map.frontOffset}" min="0" max="5" step="1" 
          @change="${({ target }: { target: BUI.NumberInput }) => {
            map.frontOffset = target.value;
          }}">
        </bim-number-input>
                
        <div style="display: flex; gap: 12px">
        
          <bim-number-input slider value="${mapSize.x}" pref="Size X" min="100" max="500" step="10"              
            @change="${({ target }: { target: BUI.NumberInput }) => {
              const size = map.getSize();
              size.x = target.value;
              map.resize(size);
            }}">
          </bim-number-input>        
        
          <bim-number-input slider value="${mapSize.y}" pref="Size Y" min="100" max="500" step="10"            
            @change="${({ target }: { target: BUI.NumberInput }) => {
              const size = map.getSize();
              size.y = target.value;
              map.resize(size);
            }}">
          </bim-number-input>
        </div>
  
        
      </bim-panel-section>
    </bim-panel>
    `;
});

document.body.append(panel);

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
      <bim-button class="phone-menu-toggler" icon="solar:settings-bold"
        @click="${() => {
          if (panel.classList.contains("options-menu-visible")) {
            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }
        }}">
      </bim-button>
    `;
});

document.body.append(button);

🎉 Wrap up​

That's it! You have created a simple app that loads a BIM model and displays a MiniMap of it. You can play around with the different parameters of the MiniMap and see how it changes in real time.

OrthoPerspectiveCamera

Source

Copying and pasting? We've got you covered! You can find the full source code of this tutorial here.

📹 How to handle a fancy camera​

Sometimes, you need perspective for depth and realism. Other times, you need an orthographic camera to get precise measurements and proportions. Luckily for you, we have a camera that has both of those projections at the same time! It also has some cool functionality for navigation. In this tutorial, you'll learn to use it.

Orthographic and Perspective cameras

The difference between Orthographic and Perspective cameras is that Orthographic cameras don't see things smaller when they are further away. This has some implications, like the camera being always "outside" of your scene. You can't see the interior of a room with an orthographic camera. The most common use for orthographic cameras are 2D floor plans and sections, but they can also be used to create cool-looking 3D scenes.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • @thatopen/ui to add some simple and cool UI menus.
  • Stats.js (optional) to measure the performance of our app.
import Stats from "stats.js";
import * as THREE from "three";
import * as BUI from "@thatopen/ui";
import * as OBC from "@thatopen/components";

🌎 Setting up the world AND the camera​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial. But there's one difference: we will use the OrthoPerspectiveCamera for initializing the world.

const container = document.getElementById("container")!;
const components = new OBC.Components();
const worlds = components.get(OBC.Worlds);

const world = worlds.create<
  OBC.SimpleScene,
  OBC.OrthoPerspectiveCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.OrthoPerspectiveCamera(components);

world.scene.setup();

await world.camera.controls.setLookAt(3, 3, 3, 0, 0, 0);

components.init();

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

Easy, right? Believe it or not, this is all you need to use the OrthoPerspectiveCamera. Now, let's see it in action!

🧊 Creating a cube​

We will start by creating a simple cube and a grid that will serve as a reference point for our camera.

const cubeGeometry = new THREE.BoxGeometry();
const cubeMaterial = new THREE.MeshStandardMaterial({ color: "#6528D7" });
const cube = new THREE.Mesh(cubeGeometry, cubeMaterial);
cube.position.set(0, 0.5, 0);

world.scene.three.add(cube);
world.meshes.add(cube);

const grids = components.get(OBC.Grids);
const grid = grids.create(world);

🎟️ Using camera events​

The OrthoPerspectiveCamera has a few events that you can use to manage the your scene. We will use the camera.projection.onChanged event to update the grid, so that when using the Orthographic camera, the grid will fade out if the camera zooms away a lot.

world.camera.projection.onChanged.add(() => {
  const projection = world.camera.projection.current;
  grid.fade = projection === "Perspective";
});

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Building a camera UI​

Now we will use @thatopen/ui to create a simple UI for the OrthoPerspectiveCamera. It will have 4 elements:

🎛️ Navigation mode​

This will control the navigation mode of the OrthoPerspectiveCamera. It will have 3 options:

  • Orbit: for 3D orbiting around the scene.
  • FirstPerson: for navigating the scene in with the mouse wheel in first person.
  • Plan: for navigating 2d plans (blocking the orbit).

📐 Projections​

Like its name implies, the OrthoPerspectiveCamera has 2 projections, and it's really easy to toggle between them. The camera position will remain the same, which is really convenient when you switch between different projections!

❌ Toggling user input​

Sometimes you might want to remove control from the user. For example, imagine you are animating the camera and you don't want the user to move the camera around. You can use the setUserInput method to toggle this.

🔎 Focusing objects​

The OrthoPerspectiveCamera has a fit method that will fit the camera to a list of meshes. This is really useful when you want to bring attention to a specific part of the scene, or for allowing your user to navigate the scene by focusing objects.

BUI.Manager.init();

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel active label="Orthoperspective Camera Tutorial" class="options-menu">

          <bim-option label="Orthographic"></bim-option>

        <bim-checkbox 
          label="Allow user input" checked 
          @change="${({ target }: { target: BUI.Checkbox }) => {
            world.camera.setUserInput(target.checked);
          }}">  
        </bim-checkbox>  
        
        <bim-button 
          label="Fit cube" 
          @click="${() => {
            world.camera.fit([cube]);
          }}">  
        </bim-button>  

      </bim-panel-section>
    </bim-panel>
    `;
});

document.body.append(panel);

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
      <bim-button class="phone-menu-toggler" icon="solar:settings-bold"
        @click="${() => {
          if (panel.classList.contains("options-menu-visible")) {
            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }
        }}">
      </bim-button>
    `;
});

document.body.append(button);

🎉 Wrap up​

That's it! We have created an OrthoPerspective camera that can be used to navigate a 3D scene with multiple projections and navigation modes, as well as a neat UI to control it. Great job!

OrthoPerspectiveCamera

Source

Copying and pasting? We've got you covered! You can find the full source code of this tutorial here.

📹 How to handle a fancy camera​

Sometimes, you need perspective for depth and realism. Other times, you need an orthographic camera to get precise measurements and proportions. Luckily for you, we have a camera that has both of those projections at the same time! It also has some cool functionality for navigation. In this tutorial, you'll learn to use it.

Orthographic and Perspective cameras

The difference between Orthographic and Perspective cameras is that Orthographic cameras don't see things smaller when they are further away. This has some implications, like the camera being always "outside" of your scene. You can't see the interior of a room with an orthographic camera. The most common use for orthographic cameras are 2D floor plans and sections, but they can also be used to create cool-looking 3D scenes.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • @thatopen/ui to add some simple and cool UI menus.
  • Stats.js (optional) to measure the performance of our app.
import Stats from "stats.js";
import * as THREE from "three";
import * as BUI from "@thatopen/ui";
import * as OBC from "@thatopen/components";

🌎 Setting up the world AND the camera​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial. But there's one difference: we will use the OrthoPerspectiveCamera for initializing the world.

const container = document.getElementById("container")!;
let components = new OBC.Components();
let worlds = components.get(OBC.Worlds);

let world = worlds.create<
  OBC.SimpleScene,
  OBC.OrthoPerspectiveCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.OrthoPerspectiveCamera(components);

world.scene.setup();

await world.camera.controls.setLookAt(3, 3, 3, 0, 0, 0);

components.init();

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

Easy, right? Believe it or not, this is all you need to use the OrthoPerspectiveCamera. Now, let's see it in action!

🧊 Creating a cube​

We will start by creating a simple cube and a grid that will serve as a reference point for our camera.

let cubeGeometry = new THREE.BoxGeometry();
let cubeMaterial = new THREE.MeshStandardMaterial({ color: "#6528D7" });
let cube = new THREE.Mesh(cubeGeometry, cubeMaterial);
cube.position.set(0, 0.5, 0);

world.scene.three.add(cube);
world.meshes.add(cube);

let grids = components.get(OBC.Grids);
let grid = grids.create(world);

🎟️ Using camera events​

The OrthoPerspectiveCamera has a few events that you can use to manage the your scene. We will use the camera.projection.onChanged event to update the grid, so that when using the Orthographic camera, the grid will fade out if the camera zooms away a lot.

world.camera.projection.onChanged.add(() => {
  const projection = world.camera.projection.current;
  grid.fade = projection === "Perspective";
});

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Building a camera UI​

Now we will use @thatopen/ui to create a simple UI for the OrthoPerspectiveCamera. It will have 4 elements:

🎛️ Navigation mode​

This will control the navigation mode of the OrthoPerspectiveCamera. It will have 3 options:

  • Orbit: for 3D orbiting around the scene.
  • FirstPerson: for navigating the scene in with the mouse wheel in first person.
  • Plan: for navigating 2d plans (blocking the orbit).

📐 Projections​

Like its name implies, the OrthoPerspectiveCamera has 2 projections, and it's really easy to toggle between them. The camera position will remain the same, which is really convenient when you switch between different projections!

❌ Toggling user input​

Sometimes you might want to remove control from the user. For example, imagine you are animating the camera and you don't want the user to move the camera around. You can use the setUserInput method to toggle this.

🔎 Focusing objects​

The OrthoPerspectiveCamera has a fit method that will fit the camera to a list of meshes. This is really useful when you want to bring attention to a specific part of the scene, or for allowing your user to navigate the scene by focusing objects.

🐁 Picking things with the mouse​

In this tutorial you'll learn how to use the Raycaster to pick objects in the scene with the mouse.

What's ray casting?

Ray casting is the process of casting a ray from a point in space to another point in space. We will cast a ray from the mouse position to the 3D world and check if there is an object in its way. That way, when you hover or click on an object, we can know which one it is and do something with it.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • Stats.js (optional) to measure the performance of our app.
import * as THREE from "three";
import Stats from "stats.js";
import * as OBC from "@thatopen/components";

🌎 Setting up a simple scene​

We will start by creating a simple scene with a camera and a renderer. If you don't know how to set up a scene, you can check the Worlds tutorial.

const container = document.getElementById("container")!;

const components = new OBC.Components();

const worlds = components.get(OBC.Worlds);
const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

world.camera.controls.setLookAt(10, 10, 10, 0, 0, 0);

world.scene.setup();

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

🧊 Adding some cubes to the scene​

Now we will add some cubes to the scene and create some materials. The idea for this app is simple: when you click on a cube, it will change its color to green.

const cubeMaterial = new THREE.MeshStandardMaterial({ color: "#6528D7" });
const greenMaterial = new THREE.MeshStandardMaterial({ color: "#BCF124" });

const boxGeometry = new THREE.BoxGeometry(3, 3, 3);

const cube1 = new THREE.Mesh(boxGeometry, cubeMaterial);
const cube2 = new THREE.Mesh(boxGeometry, cubeMaterial);
const cube3 = new THREE.Mesh(boxGeometry, cubeMaterial);
world.scene.three.add(cube1, cube2, cube3);
const cubes = [cube1, cube2, cube3];

cube2.position.x = 5;
cube3.position.x = -5;

To make this more interesting, we will add a rotation to the cubes. We can do it by subscribing to the onBeforeUpdate event of the world, which fires 60 times per second.

const oneDegree = Math.PI / 180;

function rotateCubes() {
  cube1.rotation.x += oneDegree;
  cube1.rotation.y += oneDegree;
  cube2.rotation.x += oneDegree;
  cube2.rotation.z += oneDegree;
  cube3.rotation.y += oneDegree;
  cube3.rotation.z += oneDegree;
}

world.renderer.onBeforeUpdate.add(rotateCubes);

⚡ Setting up the raycaster​

Next, we will set up the raycaster. We will use the Raycasters component. Instead of instantiating it, we will get it from the components object, which is usually safer, as all components are meant to be singletons.

const casters = components.get(OBC.Raycasters);

Each raycaster is bound to a specific world. In this case, we will get the raycaster from the world we are using for our scene:

const caster = casters.get(world);

Finally, we will subscribe to the mousemove event of the window. We will use the castRay method of the raycaster to find out if the mouse is over a cube. If it is, we will change its color to green. Otherwise, we will change its color to the original color.

let previousSelection: THREE.Mesh | null = null;

window.onmousemove = () => {
  const result = caster.castRay(cubes);
  if (previousSelection) {
    previousSelection.material = cubeMaterial;
  }
  if (!result || !(result.object instanceof THREE.Mesh)) {
    return;
  }
  result.object.material = greenMaterial;
  previousSelection = result.object;
};

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🎉 Wrap up​

That's it! We have created a simple app that uses the Raycaster to pick objects in the scene with the mouse. Easy, right? Now you can allow your users to interact with your 3D world.

Worlds

Source

Copying and pasting? We've got you covered! You can find the full source code of this tutorial here.

🌎 Creating our 3D world​

In this tutorial you'll learn how to create a simple scene using @thatopen/components.

Hello world!

A world represents a 3D environment in your application. It consists of a scene, a camera and (optionally) a renderer. You can create multiple worlds and show them in multiple viewports at the same time.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • @thatopen/ui to add some simple and cool UI menus.
  • Stats.js (optional) to measure the performance of our app.
import * as THREE from "three";
import * as BUI from "@thatopen/ui";
import * as OBC from "@thatopen/components";
import Stats from "stats.js";

🖼️ Getting the container​

Next, we need to tell the library where do we want to render the 3D scene. We have added an DIV element to this HTML page that occupies the whole width and height of the viewport. Let's fetch it by its ID:

const container = document.getElementById("container")!;

🚀 Creating a components instance​

Now we will create a new instance of the Components class. This class is the main entry point of the library. It will be used to register and manage all the components in your application.

Don't forget to dispose it when you are done!

Once you are done with your application, you need to dispose the Components instance to free up the memory. This is a requirement of Three.js, which can't dispose the memory of 3D related elements automatically.

const components = new OBC.Components();

🌎 Setting up the world​

Now we are ready to create our first world. We will use the Worlds component to manage all the worlds in your application. Instead of instancing it, we can get it from the Components instance. All components are singleton, so this is always a better way to get them.

const worlds = components.get(OBC.Worlds);

We can create a new world by calling the create method of the Worlds component. It's a generic method, so we can specify the type of the scene, the camera and the renderer we want to use.

const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

Now we can set the scene, the camera and the renderer of the world, and call the init method to start the rendering process.

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

💄 Adding things to our scene​

Now we are ready to start adding some 3D entities to our scene. We will add a simple cube:

const material = new THREE.MeshLambertMaterial({ color: "#6528D7" });
const geometry = new THREE.BoxGeometry();
const cube = new THREE.Mesh(geometry, material);
world.scene.three.add(cube);

We could also add some lights, but the SimpleScene class can do that easier for us using its setup method:

world.scene.setup();

Finally, we will make the camera look at the cube:

world.camera.controls.setLookAt(3, 3, 3, 0, 0, 0);

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Now we will create a new panel with some inputs to change the background color of the scene and the intensity of the directional and ambient lights. For more information about the UI library, you can check the specific documentation for it!

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel label="Worlds Tutorial" class="options-menu">
      <bim-panel-section collapsed label="Controls">
      
        <bim-color-input 
          label="Background Color" color="#202932" 
          @input="${({ target }: { target: BUI.ColorInput }) => {
            world.scene.three.background = new THREE.Color(target.color);
          }}">
        </bim-color-input>
        
        <bim-number-input 
          slider step="0.1" label="Directional lights intensity" value="1.5" min="0.1" max="10"
          @change="${({ target }: { target: BUI.NumberInput }) => {
            for (const child of world.scene.three.children) {
              if (child instanceof THREE.DirectionalLight) {
                child.intensity = target.value;
              }
            }
          }}">
        </bim-number-input>
        
        <bim-number-input 
          slider step="0.1" label="Ambient light intensity" value="1" min="0.1" max="5"
          @change="${({ target }: { target: BUI.NumberInput }) => {
            for (const child of world.scene.three.children) {
              if (child instanceof THREE.AmbientLight) {
                child.intensity = target.value;
              }
            }
          }}">
        </bim-number-input>
        
      </bim-panel-section>
    </bim-panel>
    `;
});

document.body.append(panel);

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
      <bim-button class="phone-menu-toggler" icon="solar:settings-bold"
        @click="${() => {
          if (panel.classList.contains("options-menu-visible")) {
            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }
        }}">
      </bim-button>
    `;
});

document.body.append(button);

🎉 Wrap up​

That's it! You have created your first 3D world and added some UI elements to it. You can now play with the inputs to see how the scene changes.

Copying and pasting? We've got you covered! You can find the full source code of this tutorial here.

🌎 Creating our 3D world​

In this tutorial you'll learn how to create a simple scene using @thatopen/components.

Hello world!

A world represents a 3D environment in your application. It consists of a scene, a camera and (optionally) a renderer. You can create multiple worlds and show them in multiple viewports at the same time.

In this tutorial, we will import:

  • Three.js to get some 3D entities for our app.
  • @thatopen/components to set up the barebone of our app.
  • @thatopen/ui to add some simple and cool UI menus.
  • Stats.js (optional) to measure the performance of our app.
import * as THREE from "three";
import * as BUI from "@thatopen/ui";
import * as OBC from "@thatopen/components";
import Stats from "stats.js";

🖼️ Getting the container​

Next, we need to tell the library where do we want to render the 3D scene. We have added an DIV element to this HTML page that occupies the whole width and height of the viewport. Let's fetch it by its ID:

const container = document.getElementById("container")!;

🚀 Creating a components instance​

Now we will create a new instance of the Components class. This class is the main entry point of the library. It will be used to register and manage all the components in your application.

Don't forget to dispose it when you are done!

Once you are done with your application, you need to dispose the Components instance to free up the memory. This is a requirement of Three.js, which can't dispose the memory of 3D related elements automatically.

const components = new OBC.Components();

🌎 Setting up the world​

Now we are ready to create our first world. We will use the Worlds component to manage all the worlds in your application. Instead of instancing it, we can get it from the Components instance. All components are singleton, so this is always a better way to get them.

const worlds = components.get(OBC.Worlds);

We can create a new world by calling the create method of the Worlds component. It's a generic method, so we can specify the type of the scene, the camera and the renderer we want to use.

const world = worlds.create<
  OBC.SimpleScene,
  OBC.SimpleCamera,
  OBC.SimpleRenderer
>();

Now we can set the scene, the camera and the renderer of the world, and call the init method to start the rendering process.

world.scene = new OBC.SimpleScene(components);
world.renderer = new OBC.SimpleRenderer(components, container);
world.camera = new OBC.SimpleCamera(components);

components.init();

We'll make the background of the scene transparent so that it looks good in our docs page, but you don't have to do that in your app!

world.scene.three.background = null;

💄 Adding things to our scene​

Now we are ready to start adding some 3D entities to our scene. We will add a simple cube:

const material = new THREE.MeshLambertMaterial({ color: "#6528D7" });
const geometry = new THREE.BoxGeometry();
const cube = new THREE.Mesh(geometry, material);
world.scene.three.add(cube);

We could also add some lights, but the SimpleScene class can do that easier for us using its setup method:

world.scene.setup();

Finally, we will make the camera look at the cube:

world.camera.controls.setLookAt(3, 3, 3, 0, 0, 0);

⏱️ Measuring the performance (optional)​

We'll use the Stats.js to measure the performance of our app. We will add it to the top left corner of the viewport. This way, we'll make sure that the memory consumption and the FPS of our app are under control.

const stats = new Stats();
stats.showPanel(2);
document.body.append(stats.dom);
stats.dom.style.left = "0px";
stats.dom.style.zIndex = "unset";
world.renderer.onBeforeUpdate.add(() => stats.begin());
world.renderer.onAfterUpdate.add(() => stats.end());

🧩 Adding some UI​

We will use the @thatopen/ui library to add some simple and cool UI elements to our app. First, we need to call the init method of the BUI.Manager class to initialize the library:

BUI.Manager.init();

Now we will create a new panel with some inputs to change the background color of the scene and the intensity of the directional and ambient lights. For more information about the UI library, you can check the specific documentation for it!

const panel = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel label="Worlds Tutorial" class="options-menu">
      <bim-panel-section collapsed label="Controls">
      
        <bim-color-input 
          label="Background Color" color="#202932" 
          @input="${({ target }: { target: BUI.ColorInput }) => {
            world.scene.three.background = new THREE.Color(target.color);
          }}">
        </bim-color-input>
        
        <bim-number-input 
          slider step="0.1" label="Directional lights intensity" value="1.5" min="0.1" max="10"
          @change="${({ target }: { target: BUI.NumberInput }) => {
            for (const child of world.scene.three.children) {
              if (child instanceof THREE.DirectionalLight) {
                child.intensity = target.value;
              }
            }
          }}">
        </bim-number-input>
        
        <bim-number-input 
          slider step="0.1" label="Ambient light intensity" value="1" min="0.1" max="5"
          @change="${({ target }: { target: BUI.NumberInput }) => {
            for (const child of world.scene.three.children) {
              if (child instanceof THREE.AmbientLight) {
                child.intensity = target.value;
              }
            }
          }}">
        </bim-number-input>
        
      </bim-panel-section>
    </bim-panel>
    `;
});

document.body.append(panel);

And we will make some logic that adds a button to the screen when the user is visiting our app from their phone, allowing to show or hide the menu. Otherwise, the menu would make the app unusable.

const button = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
      <bim-button class="phone-menu-toggler" icon="solar:settings-bold"
        @click="${() => {
          if (panel.classList.contains("options-menu-visible")) {
            panel.classList.remove("options-menu-visible");
          } else {
            panel.classList.add("options-menu-visible");
          }
        }}">
      </bim-button>
    `;
});

document.body.append(button);

🎉 Wrap up​

That's it! You have created your first 3D world and added some UI elements to it. You can now play with the inputs to see how the scene changes.

🖌️ Adding Styles​

Few final things, we need to add styles for the labels which display the measurement information.

  • ifcjs-dimension-label - The label which is used to show the metric value after both the tooltips are attached.
  • ifcjs-dimension-label:hover - Changing the styling when someone hovers on the dimension label.
  • ifcjs-dimension-preview - The label which shows the measurement when the tooltip is not yet attached.

Leveling up your app with custom components! 🔌​

One of the greatest things about the library is that you can create your own reactive and non reactive elements (statefull and stateless components respectively) in a very simple and efficient way, all thanks to the power of lit-html 💪. The UIComponent class has a static method to create functional components (UI defined as a function) that can be updated anytime. The method is UIComponent.create.

note

Despite the UIComponent is a class that can be instantiated or extended, from a developer perspective using the library is most likely it will only use the create method.

Creating an stateless component​

To start learning how to create custom components, let's create a custom component that uses the panel section:

const statelessPanelSection = BUI.Component.create<BUI.PanelSection>(() => {
  return BUI.html`
    <bim-panel-section label="Stateless Panel Section">
      <bim-color-input label="Color"></bim-color-input>
    </bim-panel-section>
  `;
});
danger

Remember to first call UIManager.init() before anything else!

UIComponent.create requires you to provide a function declaration that returns an HTML string made with the html tag function, and the result of the function is the HTMLElement it self.

note

Tag functions are special declarations that are always set before a template literals to process the string.

Did you notice the component is named statelessPanelSection? Well, the reason is because components can have an optional state. Technically speaking, that makes the create method to have two overloads: one for components with state (statefull) and another for components without state (stateless). The main difference is that statefull components lets you update them with new states (so the UI component will efficiently re-render and display new data) while stateless components never needs to be updated as they are static. -The component we just created is stateless, because it doesn't have any state in which its data depends on.

Creating a statefull component​

Now, let's take a look at how to create a component that can be updated based on state changes:

interface PanelSectionUIState {
  label: string;
  counter: number;
}

const [statefullPanelSection, updateStatefullPanelSection] =
  BUI.Component.create<BUI.PanelSection, PanelSectionUIState>(
    (state: PanelSectionUIState) => {
      const { label, counter } = state;
      const msg = `This panel section has been updated ${counter} ${counter === 1 ? "time" : "times"}`;
      return BUI.html`
      <bim-panel-section label=${label}>
        <bim-label label=${msg}></bim-label>
      </bim-panel-section>
    `;
    },
    { label: "Statefull Panel Section", counter: 0 },
  );

When you pass an object as the argument in your create function, the component has now become statefull. As you see, there are a couple of differences between the stateless and statefull components:

  1. The statefull component requires an state object (it must be an object) to be passed in the function declaration. Think on this as the classic properties object you pass to a component in a framework like React.
  2. When the component is statefull, UIComponent.create must have a second argument to specify the initial state of the component.
  3. Now, UIComponent.create does not return the HTMLElement it self, but an array where the first item is the HTMLElement and second is a function to update the component based on an updated state. Think on this as when you use the useState hook in frameworks like React.
    note

    As for now, a statefull component can't update itself! However, you can nest other components that updates the state of some other.

Nesting components​

Now, in order to see the two components in action, let's create a third component to integrate (nest) the two previous:

const panel = BUI.Component.create<BUI.Panel>(() => {
  let counter = 0;
  const onUpdateBtnClick = () => {
    counter++;
    if (counter >= 5) {
      updateStatefullPanelSection({
        label: "Powered Statefull Panel Section 💪",
        counter,
      });
    } else {
      updateStatefullPanelSection({ counter });
    }
  };

  return BUI.html`
    <bim-panel label="My Panel">
      <bim-panel-section label="Update Functions">
        <bim-button @click=${onUpdateBtnClick} label="Update Statefull Section"></bim-button>
      </bim-panel-section>
      ${statelessPanelSection}
      ${statefullPanelSection}
    </bim-panel>
  `;
});

As you see, the create function doesn't need to immediately return the HTML, but you can also do any other logic you want inside. In this case, the logic adds a listener to bim-button in order to update the state of the statefullPanelSection we created earlier. A couple of things to notice here:

  1. You're not forced to update the whole component state, but just the things you need. In this case, we just updated the panel section label in case the counter is greater than or equals to 5. However, in this case the counter is always updated.
  2. Despite we updated the component inside the logic of the panel, you can update your statefull components from anywhere in your code by just using the update function.
  3. You can nest any component in any other: statefull in stateless, stateless in stateless, etc. In this case, panel is a stateless component, but it has an statefull component inside. That means contents of a stateless component can be updated but because that content is a statefull component.
  4. You see how we integrated the two previous components into the panel? Yes, its as easy as adding them as an expression (${statelessPanelSection} and ${statefullPanelSection} in this case).
    tip

    In order to know the syntax you can write inside the template literal tagged by the html function, look at the lit-html documentation.

    Finally, you can add your panel component anywhere you want as its an HTMLElement just like any other!
document.body.append(panel);

Congratulations! You already know how to create your own custom reactive components. Don't stop learning! Take a look at more tutorials in the documentation 🙂.

tip

The complementary packages of the library such as @thatopen/ui-components-obc or @thatopen/ui-components-three have premade functional components just like the ones we've learned to create in this tutorial, so you don't need to bother to create them by yourself 😉

Displaying elements grouping 📦​

One of the greatest things we can make using BIM models is to group elements based on their properties. This has many use cases! Like grouping elements to check their collisions 💥, grouping elements based on their construction activities 🔨, or grouping fininshed elements during the construction phase ✅. Other than grouping the elements, the next most important thing is to show them to your user in an easy way... well, here is where it comes the ClassificationsTree functional component!

Creating the classifications tree​

First things first, let's create an instance of the functional component, like this:

const [classificationsTree, updateClassificationsTree] =
  CUI.tables.classificationTree({
    components,
    classifications: {},
  });

Now that we have the classifications tree created, let's tell the FragmentsManager that each time a model is loaded it needs to classify the model based on some conditions, but more importantly is that right after those classifications are made it needs to update the classifications tree!

const classifier = components.get(OBC.Classifier);

fragmentsManager.onFragmentsLoaded.add(async (model) => {
  // This creates a classification system named "entities"
  classifier.byEntity(model);

  // This creates a classification system named "predefinedTypes"
  await classifier.byPredefinedType(model);

  const classifications = {
    Entities: ["entities", "predefinedTypes"],
    "Predefined Types": ["predefinedTypes"],
  };

  updateClassificationsTree({ classifications });
});

The classifications value is just an object where they keys are the names in the tree, and the values are the orders in which you want to group the elements. So, for example, "Entities" groups the elements based on their entities and then based on their predefined types. Needless to say, the classifications need to be computed before they can be used on the tree. You can check the system names from classifier.list. Great! As we already told the UI when it needs to update, let's add the classifications tree to the HTML page. For it, let's create simple BIM panel component where we include the tree and also a pre-made IFC load button 👇

const panel = BUI.Component.create(() => {
  const [loadIfcBtn] = CUI.buttons.loadIfc({ components });

  return BUI.html`
   <bim-panel label="Classifications Tree">
    <bim-panel-section label="Importing">
      ${loadIfcBtn}
    </bim-panel-section>
    <bim-panel-section label="Classifications">
      ${classificationsTree}
    </bim-panel-section>
   </bim-panel> 
  `;
});

Finally, let's append the BIM Panel to the page to see the classifications tree working 😉

const app = document.createElement("bim-grid");
app.layouts = {
  main: {
    template: `
      "panel viewport"
      / 23rem 1fr
    `,
    elements: { panel, viewport },
  },
};

app.layout = "main";
document.body.append(app);

Congratulations! You've now a ready to go user interface that let's you show your model classifications. 🥳

Displaying data the simplest way 🔥🔥​

What is a good BIM app if you don't give users a nice way to visualize its model properties, right? Well, hold tight as here you will learn all you need to know in order to use the power of UI Components to accomplish that!

Loading a model and computing it's relations​

First things first... let's load a model 👇

const ifcLoader = components.get(OBC.IfcLoader);
await ifcLoader.setup();
const file = await fetch("/resources/small.ifc");
const buffer = await file.arrayBuffer();
const typedArray = new Uint8Array(buffer);
const model = await ifcLoader.load(typedArray);
world.scene.three.add(model);
tip

You don't need to add the model into the scene to display its properties. However, as we are going to display the properties for each selected element, then having the model into the scene is obvious, right?

Now, in order to get the most out of the properties table, you need to calculate the relations index of your model. To do it, you will need to use the IfcRelationsIndexer component from @thatopen/components to speed up the process.

const indexer = components.get(OBC.IfcRelationsIndexer);
await indexer.process(model);

Once the relations are processed, the Element Properties component has everything it needs in order to display the properties in a cool way 😎.

Creating the properties table​

Let's create an instance of the functional component, like this:

const [propertiesTable, updatePropertiesTable] = CUI.tables.elementProperties({
  components,
  fragmentIdMap: {},
});

propertiesTable.preserveStructureOnFilter = true;
propertiesTable.indentationInText = false;
tip

The elementProperties functional component is a simplified version that shows any model entity data. However, if you like a more complete properties table, use the entityAttributes component.

Cool! properties table created. Then after, let's tell the properties table to update each time the user makes a selection over the model. For it, we will use the highlighter from @thatopen/components-front:

const highlighter = components.get(OBF.Highlighter);
highlighter.setup({ world });

highlighter.events.select.onHighlight.add((fragmentIdMap) => {
  updatePropertiesTable({ fragmentIdMap });
});

highlighter.events.select.onClear.add(() =>
  updatePropertiesTable({ fragmentIdMap: {} }),
);

Creating a panel to append the table​

Allright! Let's now create a BIM Panel to control some aspects of the properties table and to trigger some functionalities like expanding the rows children and copying the values to TSV, so you can paste your element values inside a spreadsheet application 😉

const propertiesPanel = BUI.Component.create(() => {
  const onTextInput = (e: Event) => {
    const input = e.target as BUI.TextInput;
    propertiesTable.queryString = input.value !== "" ? input.value : null;
  };

  const expandTable = (e: Event) => {
    const button = e.target as BUI.Button;
    propertiesTable.expanded = !propertiesTable.expanded;
    button.label = propertiesTable.expanded ? "Collapse" : "Expand";
  };

  const copyAsTSV = async () => {
    await navigator.clipboard.writeText(propertiesTable.tsv);
  };

  return BUI.html`
    <bim-panel label="Properties">
      <bim-panel-section label="Element Data">
        <div style="display: flex; gap: 0.5rem;">
          <bim-button @click=${expandTable} label=${propertiesTable.expanded ? "Collapse" : "Expand"}></bim-button> 
          <bim-button @click=${copyAsTSV} label="Copy as TSV"></bim-button> 
        </div> 
        <bim-text-input @input=${onTextInput} placeholder="Search Property"></bim-text-input>
        ${propertiesTable}
      </bim-panel-section>
    </bim-panel>
  `;
});

Finally, let's create a BIM Grid element and provide both the panel and the viewport to display everything.

const app = document.createElement("bim-grid");
app.layouts = {
  main: {
    template: `
    "propertiesPanel viewport"
    /25rem 1fr
    `,
    elements: { propertiesPanel, viewport },
  },
};

app.layout = "main";
document.body.append(app);

Congratulations! You have now created a fully working properties table for your app in less than 5 minutes of work. Keep going with more tutorials! 💪

  updatePropertiesTable({ fragmentIdMap: {} }),
);

Creating a panel to append the table​

Allright! Let's now create a BIM Panel to control some aspects of the properties table and to trigger some functionalities like expanding the rows children and copying the values to TSV, so you can paste your element values inside a spreadsheet application 😉

const propertiesPanel = BUI.Component.create(() => {
  const onTextInput = (e: Event) => {
    const input = e.target as BUI.TextInput;
    propertiesTable.queryString = input.value !== "" ? input.value : null;
  };

  const expandTable = (e: Event) => {
    const button = e.target as BUI.Button;
    propertiesTable.expanded = !propertiesTable.expanded;
    button.label = propertiesTable.expanded ? "Collapse" : "Expand";
  };

  const copyAsTSV = async () => {
    await navigator.clipboard.writeText(propertiesTable.tsv);
  };

  return BUI.html`
    <bim-panel label="Properties">
      <bim-panel-section label="Element Data">
        <div style="display: flex; gap: 0.5rem;">
          <bim-button @click=${expandTable} label=${propertiesTable.expanded ? "Collapse" : "Expand"}></bim-button> 
          <bim-button @click=${copyAsTSV} label="Copy as TSV"></bim-button> 
        </div> 
        <bim-text-input @input=${onTextInput} placeholder="Search Property"></bim-text-input>
        ${propertiesTable}
      </bim-panel-section>
    </bim-panel>
  `;
});

Finally, let's create a BIM Grid element and provide both the panel and the viewport to display everything.

const app = document.createElement("bim-grid");
app.layouts = {
  main: {
    template: `
    "propertiesPanel viewport"
    /25rem 1fr
    `,
    elements: { propertiesPanel, viewport },
  },
};

app.layout = "main";
document.body.append(app);

Congratulations! You have now created a fully working properties table for your app in less than 5 minutes of work. Keep going with more tutorials! 💪

Displaying data the advanced way 🔥🔥​

What is a good BIM app if you don't give users a nice way to visualize its model properties, right? Well, hold tight as here you will learn all you need to know in order to use the power of UI Components to accomplish that!

Loading a model and computing it's relations​

First things first... let's load a model 👇

import * as WEBIFC from "web-ifc";
import * as BUI from "@thatopen/ui";
import * as OBC from "@thatopen/components";
import * as OBF from "@thatopen/components-front";
import * as CUI from "../..";

BUI.Manager.init();

const components = new OBC.Components();

const worlds = components.get(OBC.Worlds);

const world = worlds.create();
const sceneComponent = new OBC.SimpleScene(components);
sceneComponent.setup();
world.scene = sceneComponent;

const viewport = document.createElement("bim-viewport");
const rendererComponent = new OBC.SimpleRenderer(components, viewport);
world.renderer = rendererComponent;

const cameraComponent = new OBC.SimpleCamera(components);
world.camera = cameraComponent;
cameraComponent.controls.setLookAt(10, 5.5, 5, -4, -1, -6.5);

viewport.addEventListener("resize", () => {
  rendererComponent.resize();
  cameraComponent.updateAspect();
});

components.init();

const grids = components.get(OBC.Grids);
grids.create(world);
tip

You don't need to add the model into the scene to display its properties. However, as we are going to display the attributes for each selected element, then having the model into the scene is obvious, right?

Now, in order to get the most out of the entities table, you need to calculate the relations index of your model. To do it, you will need to use the IfcRelationsIndexer component from @thatopen/components to speed up the process.

const ifcLoader = components.get(OBC.IfcLoader);
await ifcLoader.setup();
const file = await fetch("/resources/small.ifc");
const buffer = await file.arrayBuffer();
const typedArray = new Uint8Array(buffer);
const model = await ifcLoader.load(typedArray);
world.scene.three.add(model);

Preconfiguring the table​

The attributes table has some optional configurations. One of them is the ability to modify the styles of the cell value based on the attribute value (e.g., colorizing entities with a specific string in its name, or numeric values based on a codition ). For it, let's first create a simple base style that all our cell overwrites will share:

const indexer = components.get(OBC.IfcRelationsIndexer);
await indexer.process(model);

Then, let's create an object where the keys are the attribute values you want to overwrite its styles, and the values are functions that returns an html template result.

tip

If you want to learn more about the html template tag and how to use it, just take a look at the tutorial on how to make a custom component.

const baseStyle: Record<string, string> = {
  padding: "0.25rem",
  borderRadius: "0.25rem",
};

Keep in mind the step above is optional! Not needed for the table to work. Now its time to create the table using the predefine functional component that ships with the library 🙂

const tableDefinition: BUI.TableDefinition = {
  Entity: (entity) => {
    let style = {};
    if (entity === OBC.IfcCategoryMap[WEBIFC.IFCPROPERTYSET]) {
      style = {
        ...baseStyle,
        backgroundColor: "purple",
        color: "white",
      };
    }
    if (String(entity).includes("IFCWALL")) {
      style = {
        ...baseStyle,
        backgroundColor: "green",
        color: "white",
      };
    }
    return BUI.html`<bim-label label=${entity} style=${BUI.styleMap(style)}></bim-label>`;
  },
  PredefinedType: (type) => {
    const colors = ["#1c8d83", "#3c1c8d", "#386c19", "#837c24"];
    const randomIndex = Math.floor(Math.random() * colors.length);
    const backgroundColor = colors[randomIndex];
    const style = { ...baseStyle, backgroundColor, color: "white" };
    return BUI.html`<bim-label label=${type} style=${BUI.styleMap(style)}></bim-label>`;
  },
  NominalValue: (value) => {
    let style = {};
    if (typeof value === "boolean" && value === false) {
      style = { ...baseStyle, backgroundColor: "#b13535", color: "white" };
    }
    if (typeof value === "boolean" && value === true) {
      style = { ...baseStyle, backgroundColor: "#18882c", color: "white" };
    }
    return BUI.html`<bim-label label=${value} style=${BUI.styleMap(style)}></bim-label>`;
  },
};

Cool! attributes table created. Then after, let's tell the attributes table to update each time the user makes a selection over the model. For it, we will use the Highlighter:

const [attributesTable, updateAttributesTable] = CUI.tables.entityAttributes({
  components,
  fragmentIdMap: {},
  tableDefinition,
  attributesToInclude: () => {
    const attributes: any[] = [
      "Name",
      "ContainedInStructure",
      "HasProperties",
      "HasPropertySets",
      (name: string) => name.includes("Value"),
      (name: string) => name.startsWith("Material"),
      (name: string) => name.startsWith("Relating"),
      (name: string) => {
        const ignore = ["IsGroupedBy", "IsDecomposedBy"];
        return name.startsWith("Is") && !ignore.includes(name);
      },
    ];
    return attributes;
  },
});

attributesTable.expanded = true;
attributesTable.indentationInText = true;
attributesTable.preserveStructureOnFilter = true;

Creating a panel to append the table​

Allright! Let's now create a BIM Panel to control some aspects of the attributes table and to trigger some functionalities like copying the values to TSV or exporing the data to JSON 😉

const highlighter = components.get(OBF.Highlighter);
highlighter.setup({ world });

highlighter.events.select.onHighlight.add((fragmentIdMap) => {
  updateAttributesTable({ fragmentIdMap });
});

highlighter.events.select.onClear.add(() =>
  updateAttributesTable({ fragmentIdMap: {} }),
);

Finally, let's create a BIM Grid element and provide both the panel and the viewport to display everything.

const entityAttributesPanel = BUI.Component.create(() => {
  const onSearchInput = (e: Event) => {
    const input = e.target as BUI.TextInput;
    attributesTable.queryString = input.value;
  };

  const onPreserveStructureChange = (e: Event) => {
    const checkbox = e.target as BUI.Checkbox;
    attributesTable.preserveStructureOnFilter = checkbox.checked;
  };

  const onExportJSON = () => {
    attributesTable.downloadData("entities-attributes");
  };

  const onCopyTSV = async () => {
    await navigator.clipboard.writeText(attributesTable.tsv);
    alert(
      "Table data copied as TSV in clipboard! Try to paste it in a spreadsheet app.",
    );
  };

  const onAttributesChange = (e: Event) => {
    const dropdown = e.target as BUI.Dropdown;
    updateAttributesTable({
      attributesToInclude: () => {
        const attributes: any[] = [
          ...dropdown.value,
          (name: string) => name.includes("Value"),
          (name: string) => name.startsWith("Material"),
          (name: string) => name.startsWith("Relating"),
          (name: string) => {
            const ignore = ["IsGroupedBy", "IsDecomposedBy"];
            return name.startsWith("Is") && !ignore.includes(name);
          },
        ];
        return attributes;
      },
    });
  };

  return BUI.html`

Copying and pasting? We've got you covered! You can find the full source code of this tutorial here.

Managing your loaded models 🏢​

What else can we say? The task is really simple: we need to see a list of the loaded models in the app. Let's get into it!

Setting up the components​

First of all, we're going to get the FragmentIfcLoader from an existing components instance:

const ifcLoader = components.get(OBC.IfcLoader);
await ifcLoader.setup();

The step above is super important as none of the existing functional components setup any tool, they just get it as they are! So, if we don't setup the FragmentIfcLoader then the wasm path is not going to be defined and an error will arise 🤓. Just after we have setup the loader, let's then configure the FragmentManager so any time a model is loaded it gets added to some world scene created before: 

const fragmentsManager = components.get(OBC.FragmentsManager);
fragmentsManager.onFragmentsLoaded.add((model) => {
  if (world.scene) world.scene.three.add(model);
});

Creating the models list component​

Allright! Now that some basic events are setup, it's time to create a new fresh models list component:

const [modelsList] = CUI.tables.modelsList({ components });

Now that we have a brand new models list created, we need to add it to the HTML page. For it, let's create simple BIM panel component where we include the models list and also a pre-made IFC load button 👇

const panel = BUI.Component.create(() => {
  const [loadIfcBtn] = CUI.buttons.loadIfc({ components });

  return BUI.html`
   <bim-panel label="IFC Models">
    <bim-panel-section label="Importing">
      ${loadIfcBtn}
    </bim-panel-section>
    <bim-panel-section icon="mage:box-3d-fill" label="Loaded Models">
      ${modelsList}
    </bim-panel-section>
   </bim-panel> 
  `;
});

Finally, let's append the BIM Panel to the page to see the models list working 😉

const app = document.createElement("bim-grid");
app.layouts = {
  main: {
    template: `
      "panel viewport"
      / 23rem 1fr
    `,
    elements: { panel, viewport },
  },
};

app.layout = "main";
document.body.append(app);

Congratulations! You've now a ready to go user interface that let's you show and dispose IFC models loaded into your app 🥳

Why a monorepo? 🤷‍♀️​

Easy, because we care about your final app bundle size. You see, the repositories that contains implementations of the UIComponents for different libraries, relies on the libraries to be installed in the project because they're required as peerDependencies. So, if we included all the pre-built UIComponents from @thatopen/ui-obc in the core library, you will always need to have @thatopen/components and @thatopen/components-front installed in your project even tough you're not using it.


Does these components works in my favorite framework? 🤔​

Well... yes! You name it, React? Angular? Vue? Svelte? The answer is absolutely yes. Basically, you can use these componentes anywhere HTML is accepted. If you're wondering how is that possible, is becase we're using Web Components 🔥

If you're new to Web Components, no worries! Simply put, Web Components is a browser API that let's you define your own HTML tags (DOM Elements) to be used in the document. They define the look and behavior of the elements. Have you ever seen an HTML that looks something like this?

<div>
  <unknown-tag />
</div>

As you may recall from your HTML knowledge, <unkown-tag /> is not somethings built-in in HTML... well, that's because is a Web Component! So the developer created it's own tag to use it in the document.

Web Components are extremely powerfull because they do mostly the same as the components you create in any framework, just they are framework agnostic and feel way more built-in. In other words, if you create a component in your framework you're not allowed to write the following directly in your HTML file:

<my-framework-component />

You always need to rely on your framework tools in order to render your component, so you must use JavaScript. However, if you create a Web Component you can use it in your HTML with nothing else needed.


[!IMPORTANT] Despite Web Components is a browser API, we used Lit to create the components as it makes the process way much easier. Also, we recommend checking your favorite framework documentation to implement web components, some of them needs a pretty basic setup to get up and running.

Getting Started​

To use the UIComponents, you need to install at least the core library from your terminal like this:

npm i @thatopen/ui

Then, you need to tell the library to register the components, so you can use them in any HTML syntax. To do it, in your entry JavaScript file execute the following:

import { UIManager } from "@thatopen/ui"

UIManager.init()

Finally, in your HTML file you can start to use the components!

[!TIP] You can get any icon from Iconify!

And, in your JavaScript file:

const grid = document.getElementById("grid")

grid.layouts = {
  main: `
    "header header" auto
    "sidebar content" 1fr
    "sidebar content" 1fr
    / auto 1fr
  `
}

grid.setLayout("main")

collapsed​

• Optional collapsed: boolean

Controls the collapsed state of the panel section. When collapsed is true, the content of the section is hidden, and only the header is visible. This property can be toggled to show or hide the section's content, and is reflected to an attribute for easy HTML or JavaScript manipulation. Note that sections marked as fixed ignore changes to this property.

fixed​

• Optional fixed: boolean

Determines whether the panel section is fixed, meaning it cannot be collapsed or expanded. This is useful for sections that should always remain visible.

Accessors​

value​

• get value(): Record<string, any>

The value getter computes and returns the current state of the panel section's form elements as an object. This object's keys are the name or label attributes of the child elements, and the values are the corresponding values of these elements. This property is particularly useful for retrieving a consolidated view of the user's input or selections within the panel section. When the value of any child element changes, the returned object from this getter will reflect those changes, providing a dynamic snapshot of the panel section's state. Note that this property does not have a default value as it dynamically reflects the current state of the panel section's form elements.

Returns​

Record<string, any>

Example

<bim-panel-section></bim-panel-section> <!-- Usage in HTML not directly applicable as this is a getter -->

Example

const section = document.createElement('bim-panel-section');
console.log(section.value); // Logs the current value object

• set value(data): void

The value setter allows programmatically updating the values of the panel section's child elements. It accepts an object where keys correspond to the name or label attributes of the child elements, and the values are the new values to be set for these elements. This property is useful for initializing the panel section with specific values or updating its state based on external data. When the property changes, the corresponding child elements' values are updated to reflect the new state. This does not have a default value as it is a method for updating child elements' values.

Parameters​

NameType
dataRecord<string, any>

Returns​

void

Default

undefined

Example

<bim-panel-section></bim-panel-section> <!-- Usage in HTML not directly applicable as this is a setter -->

Example
