Jay,
These are the "strange rendering results" that I just told Mohammed about.
Because your front clipping plane is so near you have lost resolution in the
Z buffer and Java 3D is not distinguishing properly between the back of your
sphere and the front. Modify the distance to the back plane so that it is
not more than 1000 times bigger than the front distance and you should be
fine.
Sounds like a cool application - what is it?
Sincerely,
Daniel Selman
