  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.
