Abstract

The method of ray tracing with cones is used to area sample objects for properly filtered rendering. Methods for generating anti-aliased reflections and refractions distorted by normal vector perturbation (bump-mapping) are developed to simulate the appearance of rippled water surfaces. The sampling aperture of the cones is distorted to anti-alias the reflections and refractions properly. A calculated texture function is used as a diffusion map for transparent surfaces to simulate the visual effect of diffuse, soft-shadowed cloud layers.
