Paper Abstract

Many surfaces scatter light in an anisotropic way, that is, for a normally incident beam, the distribution of scattered light varies as a function of the azimuthal angle of the scattered direction. Examples of surfaces with anisotropic scattering characteristics are brushed metal reflectors and certain types of diffusers. A model, based on an anisotropic scatter model proposed by Ward is introduced. The ability to fit this model to various sets of measured BSDF data is investigated. Raytracing simulations are performed using the fitted parameters, and the results are compared with experiments.
