"RotPosPathInterpolator" is a behavior, subclass it and just create the

This is a very common problem and the answer will not delight you.
I\'m sure you know that you need the Java2 plugin instead of a common
tag.
Additionally, you need even more than a J3D.jar. There are also some dlls
that need to be installed. There is no way to do that automatically. You

Nope, I just like testing in my end-user's environment, since that is
where the rubber meets the road. It's not good housekeeping, it's
thorough testing.

I've worked on Win98 and Win95, and my experiences with ATI have been
different. For the ATI Rage Pro, like you, I had no hardware acceleration
(as you said _very_ slow). However, with the Rage 128, I've had excellent
hardware acceleration on windowed OpenGL, and certainly no errors in
rendering
