Parallel Mapping

A parallel mapping object uses a cube geometry object to define the material space.

Parallel mapping has one special option: the Roll feature. The roll option rotates the Z axis of the mapping perpendicular to the surface normal, and other axes respectively. The option is most useful when texturing objects that consist of several planar surfaces. For example, one can map one brick pattern to one wall and then spread the pattern over all walls by using the roll option.
