Hi All,
I've hit what may be a lighting bug, and I wonder if someone could try to
confirm my results on their system please.
The testcase is based on one of Florin's performance tests, and displays a
number of cubes.
Each cube is in its own TransformGroup. Each TransformGroup has a yellow point

All,
Thanks for your quick feedback. If anyone can try this with a *non*-T&L card,
I'd appreciate it, to eliminate the possibility that it's a problem with the
non-T&L path of Java3D. (Alessandro - I'm unfamiliar with the Savage 4, but I

The
easiest and best approach (in my opinion) with nvidia is to set antialiasing at
driver level, not opengl/java3d/application level. Of course, I suppose you're
using winnt/2k/xp. For linux/unix I don't know.
So in
the case of windoze, just go to control panel / display / settings / GeFo
You can write a loader for your file format, or if you don't want to bother

Also,
What exactly is the front clip plane distance? This may sound like a
stupid question, but I am seeing clipping of objects before I even reach
this distance. I tested with a front clip distance of 0.05 but before I
even go 0.2 away from the object, the object got clipped. And YES,
Multiply your clip values by 7 to get the actual distances the clipping
occurs at. I've got this documented on my website page of notes (as
I've posted to the list before).

Ok, I think I figured out (problem #1) the front clip distance issue.
Basically, it's a matter of which POLICY you use for the
