Perhaps an easier solution woult be to get the coordinates of the box
(which are printed out in the main() of RubberBandBoxRendererJ3D.java)
and construct a new 2D set (in the doAction() of Cell), with these
coordinates as nodes on a path. Then add this set to the display. When
doAction() is triggered again, destroy the old 2D set and construct a
new one, add it to the display and keep doing it while(
userIsUnhappyWithSelection ;-)

Cheers,

Ugo
