Procedural HDR environment baked at runtime. Perfect mirror at fresnel center, iridescent rim. The drop that swallows the room.

Spherical harmonics displace the mesh in real time. Standing-wave nodes render as dark valleys, antinodes as gold ridges. Sound rendered as form.

Refractive crystal interior with chromatic dispersion. Inner light fractures along Snell's law per RGB channel — true rainbow refraction.

Cylindrical aurora curtains wrap a planet. Wisps driven by 3-octave fbm with vertical-falloff smoothstep. The substorm visible from space.
