Procedural Textures with Hash Functions

https://douglasorr.github.io/2025-04-hash-textures/article.html

i was thinking about #proceduralTextures again… my understanding is that techniques like perlin noise are computalionally expensive enough that they are tend to use pre-rendered noise textures instead. but it there should be a ton of smol functions that should be faster to calculate than a texture lookup?

i'm thinking something similat to what @bitartbot does… they look very paralellizable
