The camera is your eye, when you move around the object you are looking at the camera is moving, not the object. The object has a position in the 3D space, its coordinates are relative to an origin.
The bindings are the default VTK behaviour, see below how you can interact with the scene depending on the mode you have. The default mode is the Trackball Camera mode (note that all other modes are unactivated in this CGNS.NAV version).
