Abstract
An image generator system for producing real time imagery from a digital database includes processors performing in sequence: scene data management, geometry processing, and video processing. The scene data management processor selects and organizes the data base objects, modeled with polygons, and distributes polygons to parallel geometry processing modules. Geometry processing modules convert the images from 3-D to 2-D coordinates and divide the polygons into two-pixel-high scanline-aligned 'spans'. Spans are collected and sorted in a region buffer associated with each channel of a scene. Occlusion is done hierarchically to conserve time and bandwidth, and antialiasing is performed recursively for the same reasons.
