A common set of files used to support V3D files inside of Okular Plugins.

To use the plugin:

1. Add an instance of V3dModelManager as a member of your generator
2. In the loadDocument function of your generator give the model manager a pointer to the document, and add in any models located in the document:

   if (document() != nullptr) {
       m_ModelManager.SetDocument(document());
   }
   
   m_ModelManager.AddModel(V3dModel{ fileName.toStdString() }, 0);
   

3. In the generatePixmap function of you generator, cache the request, than call the Render function and present the QImage to the page however you want to:

   m_ModelManager.CacheRequest(request);
   
   QImage image = m_ModelManager.RenderModel(0, 0, (int)request->width(), (int)request->height());
   

TODO

• multi page documents - Basics are done, still need to do:
  • in the short term im assuming all pages in a document are the same size, fix this
  • the 12 pixel margin may change depending on resolution, 2k vs 4k vs 1080p
• Okular zoom optimization
• shader paths change when an external user uses the plugin
  • Currently the plugin looks for the shaders in the path that Okular is run in
• New renderer
• Clean up includes
• Clean up CMAKE files
• Look into adding a tile manager to the generator
• panning and shifting
• make the index and vertex buffers once, than cache them, currently they are recreated every time we rerender
• documentation
• Presentation Mode dosent work at all
• Customizable Controls

BUGS

• gamma3 still doesn’t work
• zooming in and out a lot can still cause a DEVICE OUT OF MEMORY vulkan error
• Opening multiple documents causes a crash
• Flickering on model movement on some systems
