When i use an event VTKRenderWindowInteractor EndInteractionEvt,   the ‘actor.GetOrientation();’ returns 0 values for the coordinate. I figured out the reason could be because the camera is rotating and not the actor, for this when I tried to rotating the actor after clicking ‘a’ from the keyboard, it works fine. Can this be made the default behavior? ie. Can the camera be made stationary and the actor is moved.

You need to use vtkInteractorStyleTrackballActor instead of
vtkInteractorStyleTrackballCamera
