- Subject: Indigo XS24 Sphere library z-buffering problems
- Lines: 13
-
- Hi, a program I am developing which uses the sphere library runs just
- fine on an IRIS 4D/220 VGS, but when I run it on a nearby Indigo XS24,
- the SPH_HEMI seems to get set true by default with SPH_ORIENT set to
- FALSE (It draws hemispheres which show up as you rotate objects on
- the screen). If I set SPH_HEMI and SPH_ORIENT to TRUE, this problem
- goes away, but then z-buffering goes away too and the appearance of
- spheres on the screen is as if they all have the same z-coordinate
- and appear in the order in which they are drawn... The Indigo is
- running 4.0.5 and zbuffer is most definitely set to TRUE...
-
- Oh, one more thing, this is in a GLX widget that this is happening...
