The author of the technique has an explanation of why screen-alined dithering is hard in their FAQ. https://github.com/runevision/Dither3D/discussions/12 Particular, it's hard to deal with anisotropy, and naive approaches to fix this hurt either break the operation as a dither with uniform dot sizes, or struggle to avoid becoming regular at angles. I agree with the claim, though, that you lose quite a lot by having the dither pattern stuck to surfaces. There is a charm to it for sure, but a high quality screen space dither would be cool. And so I experimented with some ideas and came up with one. Forgive the jank, I'm learning as I go. https://www.shadertoy.com/view/WfBGzK Note that this is using a random dither versus a patterned one, which I think hurts the aesthetics a lot, but I am certain this is incidental to the concept. I think t

here are probably much smarter techniques, and I have an idea for a large rewrite already, but those are details, just take this as a proof of concept.
In Surface-Stable Fractal Dither on Playdate
runevision·Feb 10, 2025
I'd like to expand with some more details and developments since the post I saw here a few weeks ago about my Surface-Stable Fractal Dithering technique. (That post (not by me) was here: https://news.ycombinator.com/item?id=42808889) I've since made it work also in color (RGB dithering and CMYK halftone) and demonstrated what it looks like in true 1-bit (or 3-bit for color) at low resolutions as well. See the linked demonstration video for a variety of styles/aesthetics it can be used for: https://www.youtube.com/watch?v=EzjWBmhO_1E The original explainer video is here: https://www.youtube.com/watch?v=HPqGaIMVuLs And the repository is here: https://github.com/runevision/Dither3D Lots of people both here and elsewhere has speculated about various alterations or different use cases, etc. I'd like to point to this FAQ that have a lot of comm

on topics covered. If you have questions, suggestions or similar, it would be a good idea to check that out first (after the explainer video): https://github.com/runevision/Dither3D/discussions/12 Furthermore, lots of people have been inspired to make their own implementations, or related effects inspired by Surface Stable Fractal Dithering. I keeping a list of the ones I know about here: https://github.com/runevision/Dither3D/discussions/14 For example, Aras Pranckevičius got a simplified version of the effect to work on Playdate. Since the Playdate does not have a GPU, the effect (along with 3D rasterization in general) is implemented fully CPU-based here. https://aras-p.info/blog/2025/02/09/Surface-Stable-Fractal-D... Ryan / InfernalWAVE is working on an implementation for Godot: https://x.com/InfernalWAVE_/status/1888718257122668705 arColm made shaders for MineCraft: https://bsky.app/profile/arcolm.bsky.social/post/3lhdjbrhzis... I've been surprised and happy that the effect has gotten as much interest as it has, and I'm hoping we'll eventually see games released that use this technique.
