Sorry to using confusing terms, we used Performer when we switched to
OSG; I am not very much into 3D programming, our main 3D programmer is
on vacation ...
We run one display per computer with the visualization running in full
screen mode. The full screen image displays the view as seen from the
driver's position (it's a driving simulator). A back mirror is
implemented as a separate camera that draws an image on a part of the

When it comes to details about how the Camera and the GraphichsContext
is set up, I think I have to leave this problem until our visual
programmer is back from vacation. I was just looking for an "easy" way
to try to fix a big problem ...
I appreciate very much your effort!
