i have yet to encounter something that shouldn't be expressed as a graph. three, babylon, ogl, blender, gltf, cad, games, they're all scene aligned. that doesn't seem to be a conflict since you still use shaders, physics, ecs and so on.

could you go more into detail what you mean when you say "anything non trivial"? is there a real example of something that would not be possible to create in, say, threejs?
