Hi,
I can delete them. You what, the reason is that I forget to set
ALLOW_PICKING_REPORT. The JVM does't report any capability error, so I had
no way to know that I didn't set ALLOW_PICKING_REPORT. After I read the doc,
I found that by accident.

Subject: [JAVA3D] How do I pick and delete objects? Any example?
Hi,
I have some trouble in picking and removing the object. My structure is
simple - a TransformGroup node, under which I have many BranchGroup nodes.
I want to pick and delete one BrachGroup node one time. I can not get access
to BrachGroup node, so I can not use removeChild() and detach().
My code is as following:
BranchGroup pickBG =
(BranchGroup) pickResult.getNode (PickResult.BRANCH_GROUP);
Shape3D shape = (Shape3D) pickResult.getNode (PickResult.SHAPE3D);
if (pickBG != null)
{ pickTG.removeChild (1);
System.out.println("Brach");
}
if (shape != null) {
System.out.println("Shape");
}
The problem here is that I alway got a null of 'pickBG' while 'shape' is
not null.
Why? Any comments?
Any similar example?
