[x3d-public] [X3D-Ecosystem] webgl-vs-webgpu-explained

[John Carlson]

I am willing to participate in such an experiment as I have some experience
working with Three.js in the context of
 X3D JSON with softbody2 and three-x3d-loader, but my work will be
prototyping, not a full system.  What I actually do with shaders is not a
strong point, and I’ve not used them with Three.js yet.

Someone could also modify the Three.js VRMLLoader to support shaders and/or
the WebGPURender for a quick win.
