Efficient representation of measured BRDF data using Lafortune model

The bi-directional reflectance distribution function (BRDF) describes the appearance of a material by its interaction with light. In this study, Lafortune BRDF model is fitted to densely sampled measured BRDF data by using Levenberg — Marquardt Algorithm. The obtained results are visualised by a physically based ray tracing software and the proposed method is analysed.
