I Tried Sorting Pixels

Garrett Gunnell explains how to implement an efficient real-time pixel sorting shader using parallel bitonic merge sort.

Pixel sorting has been a niche data moshing technique in the generative art community for many years, but an efficient real time pixel sorting shader for games has never been made for a few reasons. Can I solve the puzzle and invent one? Topics covered include: GPU sorting algorithms (the parallel bitonic merge sort), basic shader optimizations and advanced shader optimizations regarding memory use.
