View source for Height map

A height map is a grayscale texture used as a displacement map to define the topography of the polygons. 

Usually the brighter pixels make higher elevations, and the darker pixels make lower elevations, and 50% gray pixels make no change. Often the [[AlphaChannel|alpha channel]] of an object's texture is used for the height map. [[Landscape]]s often use height maps.
