<p>A night visual aircraft system receives flight data from an aircraft simulator, and ground light data from the gaming area data base. A computer within the night visual system organizes this image data by frame in a buffer memory according to a particular format of addresses, sequences, and bit places. The following types of image data are uniquely positioned in the format: A position vector (Vp), defining the changing position of the aircraft with respect to the terrain data origin. Rotational matrix data defining the changing attitude of the aircraft with respect to the axes of the terrain coordinate system. Light source position data defining the position of terrain lights with respect to the origin of the terrain data. CIF data, defining the direction, color, intensity, option code, and defocus (size) of individual lights. An image processor receives the formatted image data and translates and rotates to correspond to the perspective of the simulated pilot view, maintaining the directional aspect of the lights. The data is then projected into two-dimension display vectors. An image generator receives the display vectors and other image data to provide analog inputs to a CRT device mounted as a window display in the simulated aircraft.</p> |
