Do you want your camera views to appear on screen, or is it purely for the purposes of snapping images? Do you just want to snap and image once or once per frame?
I'm afraid I know nothing of opencv IPLImages. Could you elaborate?

1.) I would like to place multiple cameras (>4) manually, so the cameras
are evenly distributed in space and pointing to a center point where an
Cal3D character stands.
2.) Then render to an image from each camera. So I can create opencv
IPLImages....
I have allready done 1.), but I used Producer::Camera (I'm new in OSG)
Thx,
Goran
