This report describes the results of the second phase of a three-phase program to develop innovative, high-complexity computer image generation (CIG) system. The foundation of this CIG system is a multi-processor implementation of the z-buffer hidden-surface algorithm. The research program accomplished the following: Real-time special-purpose hardware to render shaded triangles into a displayable image; A non-real-time software simulation of the front-end of a CIG system; Software to construct databases from the Defense Mapping Agency's Digital Terrain Elevation Data tapes and from the output of a general-purpose CAD system; and Software developed to investigate additional topics in computer graphics, such as fractals, curved surfaces, transparencies, texture mapping, and level-of-detail control.
