I think the "Hacker News readers" and "People who like dithering" Venn diagram has converged slowly over time. I'm a happy resident of the overlapping zone. A classic visual explainer from the team behind Myst and Riven (who had to balance image quality and disk space) is archived here: http://web.archive.org/web/20230415173939/http://cho.cyan.com/RAWA/dither.html http://web.archive.org/web/20230415173939/http://cho.cyan.co... Obligatory link to Obra Dinn's fascinating dev log post, regarding the challenge of spatial and temporal coherence when dithering realtime 3D (for aesthetic reasons, ie. deliberately noticeable to the player): https://forums.tigsource.com/index.php?topic=40832.msg1363742#msg1363742 https://forums.tigsource.com/index.php?topic=40832.msg136374... Lately I've been attempting to add the original dithering from Excel 97's easter egg to my online reproduction. In the era of indexed-color graphics, developers had to dither efficiently to reduce banding. Compare these two rendering techniques of the same subject, one with 16 shades of gray and dithering, and the other with 256 shades of gray: https://rezmason.github.io/excel_97_egg/?shadingOnly=true&l=spikes https://rezmason.github.io/excel_97_egg/?shadingOnly=true&l=... https://rezmason.github.io/excel_97_egg/?shadingOnly=true&l=spikes&o=ctrs https://rezmason.github.io/excel_97_egg/?shadingOnly=true&l=...
