| Title: | SYSTEM AND METHOD OF VISIBLE SURFACE DETERMINATION IN COMPUTER GRAPHICS USING INTERVAL ANALYSIS | ||||||||||||||||||
| Abstract: | A system (40) is provided for visible surface determination in furtherance of photorealistic rendering in a computer graphics environment. The system includes a scene database (42) and a processor, visual characteristics of objects (64) of an image frame (44) of a scene of the scene database (42) 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 (50) of an array (62) of pixels (50) that form said image frame (44). Hierarchical occlusion buffering, in combination with an interleaved interval contraction are advantageously utilized to greatly reduce processing time. | ||||||||||||||||||
