Comparing Microfacet Multiple Scattering with Real-Life Measurements
Microfacet multiple scattering approximations change content authoring – both for good (energy conservation) and for not so good (saturation changes with roughness). I was curious how current microfacet multiple scattering techniques compare against a measured real-life reference. After all, real-life surfaces … Continue reading
