Abstract
A system and method for environment mapping determines a computer-generated object's reflective appearance, based upon position and orientation of a camera with respect to the object's location. The present invention is implemented as a real-time environment mapping for polygon rendering, however, the scope of the invention covers other rendering schemes. According to one embodiment of the present invention, a vector processing unit (VPU) uses a modified reflection formula to compute reflective properties of an object. The modified reflection formula is:
