Abstract
A three-dimensional, texture mapping display system for displaying three-dimensional projected polygons with texture map on a two-dimensional raster display screen includes a host processor and a graphics co-processor. The host processor is responsive to input data from a host memory defining an overall image that is to be displayed on a three-dimensional form on a raster display device for generating command signals, screen coordinates on the display device, and corresponding texture space coordinates on a texture memory. The graphics co-processor is responsive to the command signals, screen coordinates, and corresponding screen space coordinates for determining destination addresses for each pixel on the screen space of the display device and for determining a corresponding source address applying surface texture data to the image for each destination address. The graphics co-processor includes a look-up table for storing Z-mapping function values so as to provide delta and acceleration values in texture space which can be used to determine the source addresses.
