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 of an image frame ( 44 ) of a scene of the scene database ( 42 ) are delimited as geometric primitive. 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 ( 50 ) that form said image frame ( 44 ). |
