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.Additional Files and Images
