Heightmap

Description

Base class for all heightmaps.

A heightmap is a raster that stores geodata (e.g. elevation and/or diffuse color). The raster can be of rectangular or cubemap type. The maximum size of a heightmap (i.e. width/height, cubemap edge length) is 1.073.741.825 (i.e. 2^30+1). So a heightmap of maximum size can store up to 1.152.921.506.754.330.625 (i.e. (2^30+1)^2 = 2^60+2^31+1) geodata samples per cubemap face (rectangular type heightmaps only have one face).
