An Extension of the Combinatorial Geometry Technique for Modeling Vegetation and Terrain Features

Abstract : An extended version of the MAGI (Mathematical Applications Group, Inc.) Combinatorial Geometry technique has been developed which is capable of realistic modeling of trees and bushes. The method has been demonstrated photographically using the SYNTHAVISION process developed by MAGI. Although the basic modeling techniques are those of the standard Combinatorial Geometry method, major extensions have been introduced to reduce the strains on computer memory and computer time that are inherent in a complex description. The method will eventually be capable of integrating the tree and bush model with models of terrain features, camouflage nets and BRL-COMGEOM descriptions of vehicles. These features of the program are in progress but not yet complete.
