Re: cutaway view for 3D rendering

If you can do your cutaway view by planes, then you can set clipping
planes by the DisplayRendererJ3D.setClip() method, as illustrated
in visad/examples/

However, the wedge cliiped out of a cylinder in your JPEG cannot be
done by clipping planes. You might to this a ScalarMap to SelectRange,
of the angle coordinate of cylidrical coordinates of you cylinder.
SelectRange is illustrated in visad/examples/ Your data
would need to include a RealType with values at each point for the
angle coordinate.

Good luck,
