threejs-raymarched-space-effects
Build raymarched space phenomena in Three.js. Use for black-hole lensing, accretion disks, wormhole throat transits, curved-ray and null-geodesic integration, lensed celestial spheres, procedural star fields and galactic skies, relativistic-looking distortion, bounded volumetric structures, and GPU effects that need controlled numerical integration.

# Raymarched Space Effects
Treat these effects as numerical renderers with explicit integration state. The visual character depends on coordinate choice, step policy, and how rays interact with emissive structures.
This skill contains exemplary examples and assets beyond descriptive guidance,
they're worth studying, referencing, or even copying. Use them sufficiently
when relevant and do NOT blindly skip them.
## Workflow
1. Define the effect-space transform and camera ray.
2. Choose a physical, physically inspired, or purely artistic bending model.
3. Bound the integration domain.
4. Track ray position, direction, throughput, and accumulated radiance.
