probably true that my application is badly coded but given the lack of info
out there
on java3d, it's the best I can do...actually, from looking at my code and
comparing to
some examples I can't see much difference but I could be wrong. Anyway,
where can I get
a profile to use?
And, I don't believe the issue you described is the issue I'm having. I
simply have an
overall slowdown in everything...from rotation, zooming, panning, animation
and even
simply using the swing portion. It's like everything went to crap. And I
don't even
have anything running to take away memory or anything like that....it gets
really frustrating
to code anything when you spend 90% of the time waiting for the program to
come up and
run and only 10% coding. Grant it my computer is hardly a "power pc" but I
don't think that's
the issue I have
thanks for the input.

Well that contradicts just about everyone else's experience. I'd say you
badly coded your application in the first place. Time to pull out the
profiler and see what you are doing wrong.

Does it happen only when you drag the mouse, or at all times that the
mouse is over the window? I've come across a very annoying bug in the
combination of Swing and Java3D that exhibits this problem.
Unfortunately, I can't replicate it in a small enough test application
to actually submit it as a bug. To summarise, Java3D's renderer is
failing to grab the lock from the swing thread and then proceeds to not
update the canvas. All the behaviour loops still run at full speed, just
no pixel blitting takes place. From what I can tell, this only happens
on the mouse drag case. That is, each time the system issues a mouse
drag event, it prevents the screen from redrawing. It is proportional to
the number of drag events too. If the mouse does not move, but the
button is down, there's no problems, and the faster I move the mouse,
the longer the delay before it gets back to repainting the screen. The
visual effect is that it locks up the rendering, but the reality is that
it just skips the rendering cycle altogether.
