AbstractParameterized ray tracing is a technique that after the generation of an image by conventional ray tracing, allows changing the optical parameters of the scene and rendering a new image in a fraction of the time taken to synthesize the first one. This paper presents an enhancement to this technique that also enables the modification of two geometric parameters: light source positions and surface normal vectors (bump mapping).
