It didn't do what I expected....
I draw a polyhedron centered at (0,0,0) so that some of the
polyhderon's edges are in the -z region.
I use LineArray to define the edges.
I want to clip everything that is in the -z region.
So I set the back clipping distance by (thanks Barry)(SU = SimpleUniverse)
SU.getViewer().getView().setBackClipDistance(5.0f);
vpTrans = SU.getViewingPlatform().getViewPlatformTransform();
translate.set(0.0f, 0.0f, 5.0f);
T3D.setTranslation(translate);
vpTrans.setTransform(T3D);
When the polyhedron is displayed, it still has its -z edges displayed.
I thought by setting the back clipping distance to be the same as the
ViewingPlatform z-location that lines intersection the z=0 plane would
be cut at z=0 and lines totally beyond z=0 ( -z region) would be erased.
Any thoughts on what I am doing wrong?

Bob,
Use this to set the backClipDistance.
SU.getViewer().getView().setBackClipDistance(float distance);

Subject: [JAVA3D] SimpleUniverse View
I am using a SimpleUniverse and I want to set a back clipping distance.
I thought I would have to first get a View from the SimpleUniverse and then
use the View's methods to set the back clipping distance.
But I can't figure out how to get the View object that the SimpleUniverse
uses.
I can get the ViewPlatform with SU.getViewingPlatform() but I can't figure
out how to get the View object.
Is there any documentation on SimpleUniverse? The Java 3D API specification
does not list SimpleUniverse.
Where is the documentation for com.sun.j3d.utils.universe.*?
