Abstract

Recent measurement devices for the Bidirectional Texture Function (BTF) offer high parallel capture of the spatial varying reflectance data for material samples. We present an approach to use measurement data from homogenous materials or materials with stochastical mesostructure to obtain data samples for the fitting of BRDF models like Cook-Torrance. We applied this approach to measured samples of metallic car paint and present a novel BRDF model that enables simple editing of the car paint’s color by dividing the BTF into a model-based part, a direction-dependent color table and the spatial varying glitter effects from the effect flakes in modern car paints.
