nebulakit
Physically-derived space backgrounds, and the tools that make them.
Every nebula here is raymarched through a real 3D gas volume and exported as depth slabs, so the parallax is geometrically correct — genuine slices of one volume, not three noise fields scrolled at different speeds. Star colour is computed rather than picked: Planck's law integrated against the CIE 1931 colour-matching functions at real stellar temperatures. The gas emits on the actual lines — H-alpha, O-III and H-beta.
No AI image generation anywhere in the pipeline. It is all code, and it is all original.
