Hi Marco,

You can create a 2-D display in Java3D using:
new DisplayImplJ3D("display", new TwoDDisplayRendererJ3D())
Then you can create a visad.bom.RubberBandBoxRendererJ3D
for a RealTuple in this display. See the main() method of
visad/bom/RubberBandBoxRendererJ3D.java for an example.
Note in the CellImpl of that example, you'd call something
like:
xmap.setRange(samples[0][0], samples[0][1]);
ymap.setRange(samples[1][0], samples[1][1]);
where xmap and ymap are your ScalarMaps to XAxis and YAxis.
This would rescale the display to the bounds selected by
the rubber band box.
Good luck,
Bill
