Hi-

I've run into a problem using the clipping with Java3D 1.3b1.
A program and associated data files that exibits this behavior
is at:

ftp://ftp.unidata.ucar.edu/pub/dmurray/clip.jar

The problem is as follows:

1) If I have clipping on and the VisAD box visibile while zooming
in, the box and associated data view in the box get larger as
expected.

2) If I have clipping on and turn the VisAD box off and then
zoom,  the view only gets larger inside the area where the
box was when I turned it off (i.e. the non-visible box area
does not get any bigger). (This is best exihited by zooming out
so the box outline is small before turning it off).

3) One more interesting note is that if I add a ConstantMap
to the example and put the map at the top of the display
(1.0 on the Z Axis), if I zoom in so I go through the map
(i.e. break the 1.0 Z plane) and zoom in a little more, then
I loose all clipping and the is really shown if I zoom back
out. If I turn the box back on, then I get clipping again.

This is not a problem with Java3D 1.2.1
