Visible surface determination system & methodology in computer graphics using interval analysis

摘要

A method of photorealistic image synthesis utilizing interval-based techniques for integrating digital scene information comprises: a) executing an interval analysis upon input parameters of an image frame so as to compute a visible solution set of an area not exceeding a pixel dimension for a pixel of an array of pixels that form the image frame; b) computing the visible solution set of the area not exceeding the pixel dimension for the pixel of the array of pixels that form the image frame and c) inputting the visible solution set of the area not exceeding the pixel dimension for the pixel of the array of pixels that form the image frame to a user defined shading function in furtherance of quantitatively assigning a character to the pixel.
