Abstract : The present invention utilizes one hundred and twenty-eight unique coordinate sets to model or represent features such as moving models, projectiles, and universal features. These placeable features are combined by a coordinate set processor unit with fixed environmental features to provide a realistic visual display. Computer image generator systems have traditionally been severely limited in terms of the number of coordinate sets which could be processed. This invention overcomes prior limitations by reorganizing the necessary calculations such that an unreasonable penalty on throughput and/or hardware sizing is not leveled. Instead of transforming all coordinate sets into each display channel (this would require 128 coordinate sets X 10 channels = 1280 transformation matrices to be computed by a processor unit), all coordinate sets are first transformed in the present invention into environment space and then into specific display channels.
