Now that we are able to create models and objects within our 3D space, as well as generate backgrounds, we may want to create a more interesting environment within which to place them.

3D terrain maps provide an elegant way to define very complex landscapes. The terrain is defined using a grayscale image to set the elevation of the land. The following example shows how we can define our own landscape and simulate flying over it, or even walk on its surface:
