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.
