0 - Pushing Pixels with Lisp - Hashing on the GPU
Channel: Baggers
Date: 2017-05-17

What we did:
In this episode we pull apart a could of gpu-hashing functions.
Hashing functions often form the heart of noise functions like perlin-noise and given that noise is used -everywhere- I'd really like to get a feel for how they work.

Notes:
Phew that was nerve wracking, but a bunch of fun. I'm going to try doing this every Wednesday at 18:00 UTC so please drop by if you are interested.
