Doing the FizzleFade effect using a Feistel network
5 min read
A developer implemented Wolfenstein 3D's FizzleFade screen fade using a Feistel network instead of the original Linear Feedback Shift Register. The Feistel approach guarantees every pixel is visited exactly once in pseudo-random order without duplicates or misses, solving the LFSR's limitation of requiring a power-of-two pixel count.
