In this paper we propose a new physically plausible, anisotropic Bidirectional Reflectance Distribution Function (BRDF) for fitting and for importance … WebA Bidirectional Reflectance Distribution Function (BRDF) is a function that describes the reflectance of a surface. There are several different BRDF models/algorithms, many of which are not physically based algorithms. For a BRDF to be considered physically based, it must be energy conserving.
