procedural-stars-threejs

Generate stunning procedural night skies, starfields, nebulae, and celestial phenomena in Three.js using WebGPU compute with WebGL2 fallback. Covers scientifically-grounded starfields with spectral color temperature, magnitude-based brightness, and twinkling; volumetric nebulae with emission/absorption/reflection types; the Milky Way band; constellations with optional line overlays; planets and moons with phase lighting; shooting stars and meteor showers; aurora integration; eclipses (solar and lunar); comets with ion/dust tails; galaxies as deep-sky backdrop objects; and a full sky dome controller with time-of-night progression, moon phases, and horizon glow.
