Hades combat is deeper / requires more thought, but the forced speed run aspect of Hell Clock is really satisfying in a different way

Anisotropic perlin noise on Suzanne
New at #SIGGRAPH2025:
Can we make Perlin Noise stretch along some underlying vector field? Well it turns out it's possible with two simple additions to the original method! No need for advection or convolutions.

All PNGs had a fixed, arbitrary gamma power applied.
Now you have the option of having the correct gamma applied, if you’re into that sort of thing
