[osg-users] camera node in osg file

[Erik Sundnes Løvlie]

Yes, I need to control the camera view and animation path, and I would like
to be able to set up the complete scene (or "level" if you will, in game
terms) in blender and export it (meshes, cameras, lights, etc) to a single
file (.osg would be simplest I guess). In the code I imagine I can then
simply use the camera (or cameras) in the scene graph, with the stored
position and orientation.
