Rubber band at desired height

[Antonio Benvenuti]

Hi

following the RubberBandBoxRendererJ3D.java example, I have implemented a
simple zoom function for maps plotted on a 2D display. Now I am trying to
extend the function to a 3D display, but I am not able to set the altitude
of the box. I always get the box at altitude 0, which means it is rendered
mostly under the terrain map.

Could you help me with a hint?

Thanks.
