Abstract

For many years, appearance models in computer graphics focused on general models for reflectance functions coupled with texture maps. Recently, it has been recognized that even very common materials such as hair, skin, fabric, and rusting metal require more sophisticated models to appear realistic. This course begins with a brief review of basic reflectance models and the use of texture maps. It describes common approaches in advanced material models such as combining the effects of layers, groups of particles, and/or fibers. It surveys the detailed models needed for a wide range of materials such as plants, hair, skin, plants, inks, gems, and automotive paints, and summarizes modeling of complex appearance due to aging and weathering processes.
