Surface-Stable Fractal Dithering Explained

To create a dithering effect for 3D scenes. Doing a straight 2D dither on each frame will result in noisy artifacts and won't be "stable". Doing an "ordered" dithering produces a "porch screen" artifact effect, where there's a stable pattern in screen space that can be seen. Trying to naively map dithering patterns as textures on 3D objects again results in unstable patterns as the dithering is dependent on the distance of the screen to the object and produces noise. This is a proposed solution that maps a dithering pattern as a texture that doesn't have the "porch screen" effect and is stable. The video linked [0] to in the repo talks about experiments and shortcomings from the above I just listed. This work is in response to some challenges the developer of the "Return of the Obra Dinn" game experienced when trying to create a dithering effect in game [1] [2].

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: [link] ) 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: [link] The original explainer video is here: [this video] And the repository is here: [link] 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 common topics covered. If you have questions, suggestions or similar, it would be a good idea to check that out first (after the explainer video): [link] 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: [link] 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. [link] Ryan / InfernalWAVE is working on an implementation for Godot: [link] arColm made shaders for MineCraft: [link] I've been surprised and happy that the effect has gotten as much interest as it has, and I'm hoping w
