This program shows one way to make use of pseudo-3D texturing. It shows a landscape scene to which a pseudo-3D texture has been applied. A series of layers are defined in a texture map that describe landscape appearance at difference elevations. A position-based texgen is used with an indirect texture to select the blend of layers that should be applied at any given elevation.
