Hi Ricky, I'm not sure how to answer your question because I'm not sure what your actually asking as you mixed various different concepts up.
The osgGA camera manipulators automatically center on scenes that are loaded by taking the center and radius of the bounding sphere of the loaded model. If you don't use a camera manipulator with the viewer then you'll need to set the viewer Camera ViewMatrix directly yourself on each frame. Does this go anyway to answer your question? I'm only guess to what you might mean. Robert.
