Spectra

Category: Objects Tags: 3d, glass, dispersion, crystal, refraction, rainbow, raymarched

Refractive glass-crystal with true continuous chromatic dispersion — a spinning rainbow diamond of stacked slabs, switchable to tori, faceted gem, or a clone lattice. Two-sided refraction, Beer-Lambert tint, Fresnel rainbow edges, and optional thin-film iridescence.
