Made a try on using it for OBB computation in shader, with diff with more classical PCA, works nicely

New article on my site: HyAB k-means for color quantization
In which I try to improve color clustering with a different distance function. It's a simple technique in the end but it's pretty hard to evaluate if it's an improvement or not!

I've built a bot that creates and post a generated Zelda map using WaveFunctionCollapse. A new map every 2 hours! It's hosted on my HomeLab server.

Hey all, I wrote some WebGPU code to test some race conditions in a shader. If you're willing to try, let me know what you see. Red/flicker means there's a race.
I'm especially curious about V3 which could theoretically race but I was never able to catch it.

#Manifold v3.0 is out! This is a huge release - we have removed *all* required dependencies.
Our npm package is half the size and twice the speed. Our #SDF LevelSet is much faster and higher quality.

Hello twitter,
I used dat.gui in the past, is it still the way to go in javascript for debug UI or is there something new as easy to use ?
I know imgui but I need something in JS for this case :)
