Abstract The optical reflectance behavior of materials and surfaces is of great importance for the perception of a scene. The specific gloss and the texture of a surface give valuable hints on properties of the material it is made of; like if it is smooth or porous, soft or firm or even, in the case of a textile, if it is made from cotton- or synthetic fibers. During the early years of Computer Graphics these aspects have been slightly overlooked and materials were modeled based on quite simple assumptions about reflectance and texture appearance. Maybe this can be appointed to the fact that at that time the community had not realized the importance of surface appearance in its full extent. Another reason certainly was that materials are just particularly difficult to model due the involved micro- and mesoscopic structures which have non-trivial influence on the reflectance behavior and appearance. The standard models that have been used for surface appearance during the first two decades of computer graphics were clearly not sufficient to model this complexity in an effective and intuitive way. more...
