Hi there,
I'm getting this error which is a huge problem as it completely kills my
application and I don't know what to do. Submission deadline for my work
is in just under 2 weeks and this is the last major problem I have. I
can greatly limit my program to 4 internal frames to avoid this bug, but
this is not at all desirable.

INFO / BACKGROUND
This part of my program is in the form of MDI application with MenuBar
and ToolBar with a JDesktopPane for a load of JInternalFrames which
contain a canvas 3D.
I find that is I add more than 4 internal frames, the entire application
crashes / locks up giving that stacktrace with no reason I can find.. I
guess that it might be a bug in java3d as a result of me approchign the
problem in the wrong way.
For each JInternalFrame I have added a Canvas3D. Each Canvas3D has a
separate SimpleUniverse associated with it and the MouseBehaviors for
rotate and zoom are attached to the single main BranchGroup. Onto each
branchgroup I draw "myObject".
This is where the problem arises by adding my complicated object into
the universe on the canvas.
I've done some testingon the content of the JinternalFrames
If I just create them and add a simple JLabel to the frames.. I can keep
creating > 50 frames ad inifintum*
If I do frame.getContentPane().add(new
javax.media.j3d.Canvas3D(null)); blank canvas3d I can open 32frames
and I get error on the 33rd frame. The following also happens when I
add a canvas3d with a simple universe.
Exception occurred during event dispatching:

NEXT !!!
I create JInternalFrames, with universe, with 1 default sphere (new
Sphere()) in the main BranchGroup
Again I can only get 32 internalFrames before the crash.
FINALLY!!!
If I create my full objects as shown in the *picture attached* I get a
crash after only 4 frames
SPECS:
Hardware: 512Mb, 650MHz Athlon, 40Gb Hard Drive, 32Mb GeForce 256
(Asus),
Software: Detonator drivers v 5.13.01.1241, Java3D (OpenGL) v1.2.1_01,
JDK 1.3.0_01, Windows2000 v5.00.2195 Pro (SP2)
SOME CODE:
private void createOrganix(Group objRoot) { // test organix
Transform3D transform = new Transform3D();
Appearance app = createAppearance();
for (int i=0, total = 100; i < total; i++) {
transform.setTranslation(new Vector3f(
(float)Math.sin(i*4*Math.PI / total),
(float)Math.cos(i*4*Math.PI / (total)),
(float)Math.cos(i*2*Math.PI / (total))));
TransformGroup transGroup = new TransformGroup(transform);
Sphere blob = new Sphere(0.3f, Sphere.GENERATE_TEXTURE_COORDS
|
Sphere.GENERATE_NORMALS, 20, app);
transGroup.addChild(blob);
objRoot.addChild(transGroup);
}
}
If anyone could shed any light on what is going wrong as I haven't a
clue, I'd be very grateful. If you want to help and need more code I
can always email more. Thanks
In complete despair,
Spencer Goh
