Author here! I can only refer to an article another comment also already mentioned. It is _excellent_ and covers animation & dithering: https://bisqwit.iki.fi/story/howto/dither/jy/

HN discussion> Dithering kills your compression savings in GIF Not as much as err-diff if you use custom-palette ordered dithering, since the ordering stays the same from frame to frame the transparent-pixel optimization applies, unlike error diffusion dithering. It's what photoshop uses to create optimized gif, although their particular approach is patented alternative algorithms exist, e.g. http://bisqwit.iki.fi/story/howto/di…

HN discussionMy favorite dithering algorithm for motion video is Yliluoma dithering: https://bisqwit.iki.fi/story/howto/dither/jy/ It is especially useful for grayscale content, as finding the optimal dithering matrix from the available palette is a straightforward exact operation, and the result can be placed in a LUT for real-time rendering. In my opinion it looks much better than bayer or random dithering, especially on gradi…

HN discussionYou have two grids. Clear grid 2. Go over grid 1, calculate the new state for the current cell, write it to the second grid. At the end of a step you swap the grids.

HN discussionNeat facts: -3DFX Voodoo (all models in 16bit color depth) let you enable hardware dithering block (2x2/4x4 ordered dither, zero performance penalty). They did it to save framebuffer space (24bit textures, 16bit framebuffer). It made 3dfx graphics look significantly better than nvidia/ati in 16bit depth. Earlier cards used 4x1 filter on the output, Banshee and later models gained 2x2 filter providing "22 bit like qu…
