I am recursively setting the Appearance to new Apearance() now for all my
shape nodes:
/**
* Sets the appearance of every shape to a new appearance so they
* can release shared items and be garbage collected
*/
private void resetAppearance( Node node ) {
if (node instanceof Group) {
Group g = (Group)node;
for (int i=0;i<g.numChildren();i++) {
Node n = g.getChild(i);
resetAppearance(n);
}
} else if (node instanceof Shape3D) {
Shape3D s = (Shape3D)node;
s.setAppearance(new Appearance());
}
}
It helped but not enough. Here is more info:

Note that item 4 was allocated 3582 times, with only 2271 remaining.
Clearly its being deallocated. But item 2 was allocated 3582 times and is
never being allocated.
Item 4 is:
TRACE 5959:

The above is my code call to make the shape, this makes sense.

Looks like setLive is allocated a Shape3DRetained for every Shape3d I make.
Is this a compiled geometry? I don't know, but its NEVER going away.
Any help is appreciated.

Subject: [JAVA3D] Memory Leak?
It looks like my shapes are not being released to garbage collection after a
detach:

Notice that there are as may live objects as were ever alocated? This means
that never, in the course of my run, did one Shape3DRetained get released.
I am dropping my reference to them after detaching, so I would expect them
to go away. I know there is a bug with Shapes not being released with
shared Appearance (4182781 Shape3D memory not freed when unassigned if
associated appearance object isalive ). But I assumed that was a shared
Appearance() object, not a sub object. All my shapes share material and
texture objects, which is necessary and correct that they do so. Don't I
just detach branchgroups and let them die? or do I need to make them
"unalive" somehow?
By the way... when is the next version of Java3d going to be made available?
