Hi Erik,

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
