I would like to understand how to create perlin noise in general.
And how to specifically create perlin noise in the graphics shader language.
Where I can find good resources or tutorial for this?
I have found some tutorial from perlin himself, but it wasnt detailed enough and I couldnt understand how to create perlin noise from it.

For use on GPUs, I would just upload a pregenerated noise texture. Generating noise directly on the GPU is actually quite tricky (and slow).
