vtkInteractorStyle - provide event-driven interface to the rendering window
vtkInteractorStyle is a base class implementing the majority of motion control routines and defines an event driven interface to support vtkRenderWindowInteractor. vtkRenderWindowInteractor implements platform dependent key/mouse routing and timer control, which forwards events in a neutral form to vtkInteractorStyle.
vtkInteractorStyle can be subclassed to provide new interaction styles and a facility to override any of the default mouse/key operations which currently handle trackball or joystick styles is provided. Note that this class will fire a variety of events that can be watched using an observer, such as AnimationEvent, MouseMoveEvent, LeftButtonPressEvent, LeftButtonReleaseEvent, MiddleButtonPressEvent, MiddleButtonReleaseEvent, RightButtonPressEvent, RightButtonReleaseEvent, KeyPressEvent, KeyUpEvent,
vtkInteractorStyle subclasses may implement various styles of interaction. Some common controls are
Keypress r: reset the camera view along the current view
direction. Centers the actors and moves the camera so that all actors are visible.
Keypress s: modify the representation of all actors so that they are
Keypress w: modify the representation of all actors so that they are
