The cube mapping object allows six different materials to be associated with an object - one for each side of the cube. This is particularly useful when setting up environment maps.
A cube mapping has the following object specific controls:
Volumetric Map: This cube mapping type uses 6 pyramid maps, one from each face of the cube into the center point of the cube.
Environment Map: The material is chosen using the reflected ray direction. This mapping can be used to simulate reflective surfaces inside a room interior.
Surface Normal Map: The material is chosen according to the surface normal direction.
Front, Back, Top, Bottom, Left, Right Material: The six materials, from which one is chosen for the examined point using the selection rules (Volumetric/Environment/Normal) described above.
The geometric properties of a cube map are the same as those defined by the cube geometry object.
