Abstract
In this paper we discuss an approach for solving the problem of rendering a shaded sequence of views of a polyhedral scene with shadows and with hidden surfaces removed. We concentrate specifically on the hidden surface problem, the computational of shadow regions, and video-rate display. The method relies on a precomputation phase which constructs the aspect representation, a representation which encodes visibility information for each face in the model. The method exploits the frame-to-frame coherence present in such a sequence by deriving from the aspect representation only the changes in appearance with respect to viewpoint. The primary off-line cost of the shaded display is the cost associated with constructing the aspect representation. The primary online cost is the scan-conversion of the visible surfaces and shadow polygons.
