Texture Based Clipping
User defined clipping planes allow the clipping of geometry to arbitrary planes. While up to six planes may be defined when using software vertex processing, many drivers do not support user defined clipping planes in conjunction with hardware vertex processing; one major vendor even removed support from the latest versions of their drivers. This article shows an alternative method that allows clipping to user defined planes, while still realizing the performance gains of hardware transformation and lighting, without requiring explicit driver support. Demo application and source code provided.
