ABSTRACT:
A visual display system of the computer generated image type, for a ground based flight-simulator having a rectangular raster-scanned display and having a surface detail information store for providing a visual display of textured surfaces in perspective during simulated flight. The system includes a surface detail generator comprising a perspective transformation computer and a surface detail store. The perspective transformation computer is organized as a pipeline processor to computete in real time the perspective transformation from the textured surface (ground) plane to the display plane. Scanning of the surface detail store is controlled in a manner comparable with a trapezium scan of a photographic image, for the purpose of the perspective transformation.
