<p>A system is provided for visible surface determination in furtherance of photorealistic rendering in a computer graphics environment. The system includes a scene database and a processor, visual characteristics of objects of an image frame of a scene of the scene database are delimited as geometric primitives, more particularly, non linear functions. The processor, for executing an interval analysis, to a user degree of certainty, accurately and deterministically ascertains a visible solution set of an area not exceeding a pixel dimension for a pixel of an array of pixels that form said image frame. Hierarchical occlusion buffering, in combination with an interleaved interval contraction are advantageously utilized to greatly reduce processing time.</p> |
