Multiple-scattering BRDF

With rombo Reflect shaders, – we’re introducing microfacet multiple-scattering. The microfaceting theory that is the fundation of the BRDF implementations out there is actually single-scattering. Microfacet models assume that the true physical surface is offset from a geometric surface in the form of a collection of microfacets called microsurface. Microfacet theory is a statistical model[…]
