Abstract
A look-ahead image is employed during ray tracing of the image rendering process to eliminate the processing of pixels which are of no interest within a given boundary of the ray. During rendering, ray tracing is carried out by jumping over the pixels of no interest to thereby enhance the rendering speed.
