Abstract
Because of the high complexity of the real world, realisticsimulation of natural scenes is very costly in computation. Thetopographical subtlety of common natural features such as trees andclouds remains a stumbling block to cost-effective computermodeling. A new scene model, composed of quadric surfaces boundedwith planes and overlaid with texturing, provides an efficient andeffective means of representing a wide range, of natural features.The new model provides a compact and functional data base whichminimizes the number of scene elements. Efficient hidden surfacealgorithms for quadric surfaces bounded by planes are included. Amathematical texturing function represents natural surface detailin a statistical manner. Techniques have been developed to simulatenatural scenes with the artistic efficiency of an impressionistpainter.Keywords
