Camera::setViewMatrix*(..) affects the position of the view. Camera::setProjectionMatrix*(..) has no effect whatsoever on the position of the view, it only affects the field of view. I sounds like you are confusing various concepts, I've done by best to clear, but in the end I can't teach you basics of 3D graphics, I would suggest you spend some time learning about the topic from books and various online resources. The naming conventions used by the OSG are the same as OpenGL so general docs on 3D graphics and OpenGL will help you along your way.
