Rune Skovbo Johansen explains his open-source surface-stable fractal dithering technique, detailing the experiments and challenges of making dithering stick to 3D surfaces.

I invented a new form of dithering I call Surface-Stable Fractal Dithering. I've released it as open source along with this explainer video of how it works. Also see my demo video showing a variety of styles, including in color: youtube.com/watch?v=EzjWBmhO_1E Find the shader source and example project here: github.com/runevision/Dither3D See the FAQ here for commonly asked questions: github.com/runevision/Dither3D/discussions/12 More info on what I've been up to here: blog.runevision.com Get Lucas Pope's game Return of the Obra Dinn: obradinn.com/ Get my game Eye of the Temple: eyeofthetemple.com/ Find me on social media: bsky.app/profile/runevision.bsky.social mastodon.gamedev.place/@runevision Join my Discord server: discord.gg/yGN7bDQ Background music: "Black Swan" by Quincas Moreira "Main Theme" from Return of the Obra Dinn OST by Lucas Pope "After All" by Geographer "June" by Bobby Richards "Gently, Onwards" by ELPHNT "A Mystic Experience" by Unicorn Heads "In the Atmosphere" by Bad Snacks "Final Girl" by Jeremy Blake "Forgotten Temple" from Eye of the Temple OST by Claudi Martinez Chapters: Introduction Introducing Obra Dinn Dithering basics Dithering in Obra Dinn Scaling by nearest power of two Bayer threshold map deep dive Fractal levels and layers Math time More dots keep appearing Interlude Elusive shading It works!

What people say. Recommended as a fascinating deep dive into solving the challenges of 3D surface-stable dithering, inspired by Return of the Obra Dinn.

…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. 0 link to this video 1 link 2 link…

On a similar note, yesterday I stumbled across a 4-days old video related to dithering which is really worth watching. " Surface-Stable Fractal Dithering " 0 by "Rune Skovbo Johansen, indie game developer and procedural generation enthusiast" 0 link to this video

Somewhat related and worth watching: Surface-stable fractal dithering explained link to this video There's a follow-up video to that one.

And here's a couple videos about a technique that was inspired by the Obra Dinn's dither, but making it surface stable: link to this video (explanation) link (demo)

On “The Art of Dithering and Retro Shading for the Web (2024)”

Ah, thats from runevision. I recently whatched his youtube video on this ( link to this video ) and "Return of the Obra Dinn" was also the first thing I thought of.

…. (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: link to 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): [l…

I think implementing a dithering algorithm is one of the most satisfying projects, because it is fun, small(ish) and you know when you are done. Of course, unless you are trying to implement something completely insane like Surface-Stable Fractal Dithering link to this video
