Earlier quoted context omitted.

The tooling they wrote to make this kind of thing is absolutely insane too.

Do you have any interesting links regarding that?

Amazing.

The intro was released in 2017, so the title might need a tag. Not sure about the article, couldn't easily find a date.

Does anyone know what the assumed rendering technology is? It's a Windows executable, so I guess it can use any Windows APIs for rendering and audio? Direct3D?

At the bottom of the article, it mentions that it was released a few days ago.

It doesn't say what the environment is. 64K Commodore 64?

In the demoscene, 4K and 64K “demos” are common conventions. They refer to programs that utilize built-in system libraries + 4 kilobytes or 64 kilobytes of custom code with no additional data.

People more often talk about "4k intros" or "64k intros" to be clear (intros being size-restriced demos), often retro-people at events also but then people talk about the "C-64" in those cases (and the technologies and capabilities used is so different that it's hard to confuse the two in practice).

Windows (presumably x86)

The article yes, many people use linux,osX or BSD though so some productions using them pop up from time to time even if the majority is windows based. Some people do 64k's (or 40k's) for old Amiga computers also but those have other constraints so generated meshes aren't as popular.

On 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.
