The basic design of the Graphics object is like following.
Graphics is declared as an empty abstract class. In case other renderers, have their own implementations of it. Almost each Processing API is also a method of
Graphicsobject so I skipped defining abstract methods for each of them. As that would be too much redundant code and time-consuming.In the skia implementation, I am creating a new Renderer, canvas, surface, path and paint for each graphics object.
Then the methods are
bindedto the Graphics objects in a kind of unconventional way, but it works properly.The major scope of improvement here is to use a GPU-backed surface for smoother rendering. I need to dig more into how
glfwcontexts work and how can I create an offscreen context for surfaces.Currently it's a CPU backed surface and the offscreen sketches are not that smooth. I will open an issue for this.
