Does a java3d program automatically use hardware acceleration
(openGL/direct3d) of the user?  I have a simple program that loads a
large vrml object (5megs) and allow the user to simply walk around
(using javas navigation behaviours).  However, I find that it is
incredibly choppy.  Im using an ATI9500 (64megs) so I wasn't exactly
expecting to have any choppiness.

Is there something I have to declare for the program to use hardware
acceleration or is it just that my model is rather large?
