TERRAINS, NORMALS, AND A HEIGHTMAP
Feb 23, 2013
Heightmaps can make our lives a lot easier. When making a terrain, for example, we can use the height map's color to specify the height. If the heightmap is placed on the x-y plane, we can use the RGB values of the image to define a certain height (z) at that point. It makes terrain creation much easier than hard-coding the points in and it's easy to change!
