A present novel and non-trivial system, apparatus, and method for presenting a monochrome, three-dimensional image of terrain on a Head-Up Display (“HUD”) unit is disclosed. Based upon aircraft navigation and terrain data, an image data set representative of a lighted solid image of terrain comprised of a plurality of intensities of one color may be generated. The image data set may be determined as a function of terrain data and color intensity data, where the color intensity data could be comprised of one or more shading effects, one or more texturing ...
A present novel and non-trivial system, apparatus, and method for presenting a monochrome, three-dimensional image of terrain on a Head-Up Display (“HUD”) unit is disclosed. Based upon aircraft navigation and terrain data, an image data set representative of a lighted solid image of terrain comprised of a plurality of intensities of one color may be generated. The image data set may be determined as a function of terrain data and color intensity data, where the color intensity data could be comprised of one or more shading effects, one or more texturing effects, or a combination of both. Based upon the image data set, a three-dimensional perspective of a terrain scene outside the aircraft may be presented to the pilot.
