Fresnel Microfacet BRDF: Unification of Polari-Radiometric Surface-Body Reflection

Observation Lambertian [15] + T-S [26] Ours Intensity Figure 1. We derive Fresnel Microfacet BRDF, a novel physically-based BRDF model which consolidates radiometric (left) and polarimetric (right) reflection as well as body and surface reflections of surface microgeometry in a single model. The model outperforms past physically-based models (e.g., Lambertian [15] plus Torrance-Sparrow [26] and pBRDF [2]) in accuracy and generality.
