Suppose you have one BranchGroup object. All the objects in the scene
are attached to this object. This Object is
attached to the Universe object(usually SimpleUniverse).
And you want to display this BranchGroup object in several different
windows?
How do you open a new instance?
You create new Frame or Panel or JFrame or JPanel and add the
Canvas3D object that is already displayed in another Frame or Panel, suppose?
Remember:
When you attach the BranchGroup object to the SimpleUniverse, this
object becomes live and compiled. And it no longer can be modified.
In order to modify the BranchGroup object, before adding this object to a universe
branchGroup.setCapability(ALLOW_DETACH) must be set. So you will be
able to detach the branchGroup (branchGroup.detach()) and ONLY THEN
modify it.
