Use a DEF to name the Shape nodes in the VRML file. Then use
VrmlScene.getNamedObjects() to get a reference to the Java3D implementation for
the Shape. This will be a Link to a SharedGroup containing the Shape3D. You
can either use the Link or follow the link to the SharedGroup and detach the
Shape3D from the SharedGroup (assuming the scene is not live).
You get a Link to the node instead of a reference to the Shape3D because the
VRML loader is returning a new instance of the implementation of the VRML node
for you to use. Since the VRML Java3D tree is already has a reference to the
Shape3D, we need to use a Link/SharedGroup to allow multiple uses of the
Shape3D.
