Detailed Description

Static class containing source for vertex programs for extruding shadow volumes.

Remarks:

This exists so we don't have to be dependent on an external media files. Assembler is used so we don't have to rely on particular plugins. The assembler contents of this file were generated from the following Cg:

        // Point light shadow volume extrude
