Do this:
DisplayImplJ3D display = ...
DisplayRendererJ3D dr
(DisplayRendererJ3D) display.getDisplayRenderer();
BranchGroup root = dr.getRoot();
Then you can add Java3D lights as children of root. If you want
lights that rotate, pan and zoom with the data, then use:
TransformGroup trans = dr.getTrans();
and add lights to trans.
Good luck,
Bill
