Karthik,
This simply means that you've added this object to another parent
already.
For example, if you have:
TransformGroup tgA = new TransformGroup();
BranchGroup bgA = new BranchGroup();
BranchGroup bgB = new BranchGroup();
bgA.addChild( tgA );
bgB.addChild( tgA);
The last line will throw the exception you've indicated.
This is indicating that you've attached something to two parents.
Example of BAD code snippet:
Shape3D s3d = new Shape3D();
TransformGroup tgA = new TransformGroup();
TransformGroup tgB = new TransformGroup();
tgA.addChild(s3d);
tgB.addChild(s3d); // <- BAD! s3d already has a parent!
You can NOT clone Shape3Ds like this. What you want for something like
this is to put the Shape3D in a SharedGroup and then make links.
