Real-time simulation of a point system having textured areas as viewed by a moving observer

Abstract From the Canadian patent

A night visual aircraft system for receiving flight data from an aircraft simulator, and terrain data from the gaming area data base, includes a computer which organizes this image data by frame in a buffer memory according to a particular format of addresses, sequences and bit places The, image data includes texture data for defining areas to be activated on the CRT such as runways, horizon glow and faces, of structures. An image processor receives the light source portion of the formatted image data to translate the data into the aircraft coordinate system, rotate the data in accordance with the attitude of the aircraft, and project the data in two-dimension display coordinates. A texture …
