Wow, I've bookmarked the article for future reference, this is all very cool! I have been working in OpenGL recently on procedural meshes, particularly with L-Systems. My method for drawing branching structures was basically the same as the "Extruding" action the article talks about. The rotating of the splines around an axis is very clever! I am definitely going to use that.

#32I wonder how to train a large neural net in order to "diffuse" 3D mesh and animations.

L-Systems are indeed a very good way to get started. We didn't mention it in this article, but it could have been part of the first section. Our demo with cubes intensively used L-systems to organize and animate the cubes (it was briefly mentioned in the making-of - https://www.ctrl-alt-test.fr/2010/behind-incubation/).

If you wanted to use this for a 64k demo then your next trick would be figuring out how to cram it into less than that - you need room for all the code that actually uses the models, as well as the sound, sequencing, and whatnot.

#35On the topic of demo, honestly one of the communities I miss from the twitter downfall is one tweet shaders. As someone without a graphics background, almost everything on https://nitter.net/search?q=%23つぶやきGLSL is straight up pure magic.
You might enjoy checking https://www.shadertoy.com/ . The shaders there are likely to be longer than a tweet, but that also means they're more readable and it can be a good way to understand how they work.
They have an Android app.

#36If you are interested in learning demoscene stuff, Revision 2023 which is about to take place in roughly two weeks, features some workshops in this regard also available as online streams.
+1 to attending Revision 2023 (in Saarbrücken or online): https://2023.revision-party.net/ I'm the author of the article, and I'll be at Revision. I'll give a seminar on shader minification -- another topic not discussed in the article.
Will there be open live streams for everyone to access this year also? I watched Revision live during most of the event and it was definitely a high-point for me. I want to go in person also some time, but not this year.

Yes.
