Please point me to references that deal with line clipping in three dimensions. I have the standard references to Cohen-Sutherland, and Liang- Barsky. What I need are papers that go beyond "our 2-d line clipping algorithm can be easily extended to clip lines in three dimensions". Thanks very much Swami Manohar

You just have to do a little work. Think about what the outcodes mean and make them handle the 3D case. There may be better solutions, but 3D cohen-sutherland is quite straight forward, and still fast. ______________________________________________________________________________ Steven Hayes | steveh@goanna.cs.rmit.oz.au Royal Melbourne Institute of Technology (RMIT) | rcssjh@minyos.xx.rmit.oz.au ______________________________________________________________________________
