[x3d-public] Python authoring/mesh editing; Web3D TypeScript engine

[John Carlson]

Sorry for more posts.

Other choices are pygfx+trimesh and Panda3d.  pygfx is like Three.JS, but
in Python and is supported by webgpu packages.  Panda3d uses older shading
languages, it looks like.

Searching the web…

A TypeScript WebGPU Web3D engine.  Beta! Runs in Chrome/Edge 113+ right
now.  Not tested by me.

Kotlin and webgpu:

I think I will probably work on creating a renderer using pygfx that
renders x3d.py subclassed scenes.  I will focus on authoring
PyIndexedFaceSets, PyGroups and PyTransforms first, which hopefully will
satisfy my use  case.  Ultimately, I will view the functions as compatible
with x3d.py (with some work).  I don’t know about events yet.

Anyway.  I’m trying to keep up with WebGPU, etc.

I’m favoring non-web renderers right now. I realize that JavaScript support
will be minimal.  Ultimately, I’ll move towards Script nodes.

Hopefully all the webgpu stuff will be integrated into Modular Mojo at some
point.

A big question at this point is, does x3d.py support parent nodes in the
scenegraph?

Thanks!

John
