Abstract
A method for computer image generation simulated visual scenes for applications such as flight training. The processing to generate the image takes place in three sequential stages: Controller, Geometry Processor, and Display Processor. At any point in time, the stages are processing data for three consecutive scenes. Each scene is comprised of a plurality of faces. Processing prior to the Display Processor accomplishes clipping and perspective transformation of faces. The Display Processor then generates the scene with pipeline processing accomplishing four major tasks: span detection or windowing, span sequencing, mask processing, and color processing. The improved realism of the computer generated image includes application of area-times-color smoothing, using fractional face areas to improve scene quality and reduce quantizing artifacts.
