Abstract:
The visual system within an aircraft flight simulation system receives flight data from a flight simulation computer, and terrain data from a gaming area data base. A computer within the visual system organizes this image data in a buffer memory according to a particular format, and forwards the image data to an image processor. The following types of data are formatted and processed:
Position vectors, defining the changing position of the aircraft with respect to the origin of the terrain coordinate system.
Rotational data, defining the changing attitude of the aircraft with respect to the terrain coordinate system.
Initialization vectors, defining the position of the landmark points within the terrain coordinate system. The landmark points are translated into the aircraft coordinate system to form translated vectors.
Delta data, defining the position of other points, lines, and faces with respect to the landmark points.
