currently no, TBH it's not planned since my goal was to have a quick way to export video from my games/renderer. Feel free to fork the repo and add the features you need.

Also, there’s a benchmark in the repo at /test/benchmark.c that profiles BC1 crunch/decrunch—make sure to compile with optimization flags.

I’ve updated the BC4 algorithm and I’m curious whether it improves the compression ratio on your textures as well. For reference, my AO/displacement map went from 1.051032 to 1.211644 (a 15.3% gain). I have still some ideas left, I will try to continue to improve more.

Update, I changed the heuristic for BC4 streams, went from an average ratio of 1.051032 to 1.211644. Tested on AO, displacement map (check textures/bc4 folder)

Thanks! I haven't had time to profile decompression yet, so that measurement is really helpful. Would you mind if I add that number to the project page?

Thanks for the feedback! I agree on BC4/5 — right now it’s a bit hit-or-miss and too dependent on input noise. The algorithm still needs improvement there. I’m currently building a BC5 test texture set, which should help compare different approaches more reliably.

Don't hesitate to message me if you find a bug or if you have a question or feedback. I will update the readme with the BC4 benchmark soon.

thank you for the feedback :)

Yes brute may work, but actually I'm trying to achieve good performances and use the "right" amount of sdf shapes. My test involved a bit, now I'm using capsule (blue)+box (green, for the sharp endpoints) and biarc (red). Still to handle the worst case (all control points colinear though)

bsky only used the first image of my apng so let's use gif like it's 1998

it's "only" cats, imagine kids around waiting for you to entertain them all day :'(

By the way, the images only contain circles. Circles of the same color blend together using smoothmin. Each “splat” has its own alpha value and blends with what’s underneath.

yes, good catch! I've updated the readme with a new section for integration. Hope it clarifies the interface a bit. Don't hesitate to poke me if you have any questions.
