ABSTRACT:
A method for displaying terrain features of a topological map incudes the determination of resultant slopes between data points comprising the map. The slopes are represented by different levels of pixel intensity which are displayed upon a raster scan projection device. In an alternate embodiment of the invention, a point source of light is used to illuminate the topological surface. Normals to the surface are determined which indicate how much light would be reflected by the point light source. The amount of light reflected is then determined for each of the points of the map. The different light intensities are graded into various shades or intensities of light and displayed upon a raster display device.
