I second this recommendation, Inigo Quilez is amazing!

If you're interested in learning the fundamentals of some of the math he uses, I can highly recommend the CMU computer graphics course. It's free on YouTube.

The professor, Keenan Crane, puts out a ton of super interesting, high-quality research as well. His website is awesome.

IQ is the man! He’s the dev behind ShaderToy. He’s seen as somewhat of a Gandalf figure in the amateur shader dev community; some of what he produces in GLSL is light years beyond what most devs can conceptualize in a shader.

He's pretty much the GOAT of SDF art, and as such he created https://shadertoy.com if you're interested in that kind of stuff.

Was about to link the exact same thing. For context, Inigo is one of the authors of Shadertoy.

https://youtube.com/@TheArtofCodeIsCool has been my favourite so far, and he focuses on writing shaders. This seems like the next logical step thank you for sharing!
