- I tried this on my Indigo Elan (running IRIX 4.0.2) with a simple scene made
- up of two depthcued polygons that rotate around the scene with parts of each
- polygon being cut out by the front, back, left, and right clipping planes as
- they go, and I don't see any problems with the depthcueing of the remaining
- portions of the polygons. What machine are you seeing this problem on?
