The front page of this website has a 3d demo'ish interactive ui. Love it. https://acko.net/
Great article.
Not related to ML/AI or Stable Diffusion.
It's about generating 3D blue noise for rendering, it's very interesting on its own but the title is misleading.
Why does this site block zooming on mobile? What's the reason? I won't read a reader hostile blog

looks at the tool
It's implemented in TS.
When you generate blue noise by shaping in the frequency domain and transforming, the samples are gaussian distributed, not uniform, as the author mentions. I wonder if you can transform to a uniform distribution by sorting the samples, choosing 256 bins of equal size, then quantizing each pixel into those bins. That would be fast: O(n log n) in number or pixels.
Changing from gaussian to uniform is a distortion that presumably adds harmonics, but since they can only be higher frequencies than the original, the noise should still be blue.
