Hi Sukender, :-)
Well, what I want is the ability to have the terrain to "appear" to
remain "still" while I move the camera around on it. The glider example
and the animate example are what I'm basing my research/work on and in
both cases, when the "camera moves" it appears that the object I'm
looking at is actually moving and not the camera.
So, I must be able to "move" through the terrain like the
TrackballManipulator allows but move the camera and leave the terrain
"still."
Is this any clearer? I've looked W the link you provided but I've NO
clue as to how to use what you are suggesting. I'm too much a newbie to
3d Visualization - about 1.5 yrs worth - to understand what you're
referring to. If you know of any example(s) that I could look @ and
copy, that would be awesome!!! Do you know of or have any?

Hi Allen,
Do you mean you want a subgraph to appear as if it was at an infinite distance,
such as for skyboxes?
If so, you can try to create your own transform that removes the translation.
That costs 4 lines of code (See
http://pvle.sourceforge.net/Doc/Html/MoveWithEyePointTransform_8h-source.html
for an example).
You may also create a transform that removes rotation if needed.
Sincerely,
Sukender
