  abstract =   "We introduce a physically plausible mathematical model for a
               large class of BRDFs. The new model can be defined in a
               user-friendly way and it is as simple as the well-known
               Phong model, without any of its disadvantages. It gives a
               good visual approximation of a lot of practical materials:
               metals, plastics, ceramics, retro-reflective paints,
               anisotropic materials, etc. The new model includes the ideal
               diffuse model and ideal mirror as well, reflecting all of
               the incoming energy. Because of its illustrative properties
               it can be used easily in most commercial software and
               because of its low computational cost it is                 
               practical for VR.",
