Just to let you know...here is my system:
Pentium 2 450 Mhz.
512 MB memory
TNT 1 Graphics card
Windows 2000 (and Max OS X :)
JDK 1.4.1_01
Java3D 1.3.1 beta1
For scenes of similar complexity I get roughly 30-60 FPS. (nothing scientific,
but suffice it to say that it can be 'smooth', even on old computers).
I think that you must be using some terribly large textures or super-super
acurate spheres or something. Also I look at the small model...I suspect it
was exported from a CAD tool or something with LOTS of polys. Exporters can be
pure evil :)
With a computer as fast as yours...you should be able to get 40-60 FPS out of
something like that, easy. Scale your models accuracy and texture size down.
I bet you'll be surprised how fast you can make it.

Hi,
I have a program (picture attached) which has a canvas3d and couple of
canvas2d's and a swing interface.
When I run this program (with the canvas3d animation running) on a Pentium
3, 900 Mhz, 128Mb Ram, Nvidia TNT2,
I get pretty crappy frame rate and graphical update. I'm talking about 5
frames/second. This includes the
animation of the mercator projection and the plot which are at the bottom of
the display.
What I want to know is do any of you have any suggestions for how to improve
the frame rate. Could my
code be so badly written? I try to minimize the number of Transforms and
Groups as possible. I did notice
that having my sliders be updated by my animation slows me down some so I'm
going to have flag to not
have them get updated if the computer is too slow. But I'd still appreciate
any other advice...and
also, is there any code out there that one could run and have it output the
framerate....so that I could
use that code and test the machines out to see what framerates are possible?
I know there is a Java3D FAQ regarding speed up and I've read it. The thing
that worries me about my code
being slow is that I know people are making Java3D games and I imagine they
must be fast enough to play
so they must be doing something right.
