Height maps are used to store values such as terrain elevation for the use in 3D computer graphics and/or game development (bump mapping, displacement mapping, cloud opacity, fractal noise, etc.). Heightmaps come in two forms: grayscale and color. Grayscale heightmap's are visualized as luma of grayscale (black to white) with black representing the lowest elevations of the terrain and white the highest elevations (peaks). Color height map's are visualized through a color gradient (blue to whi
