/**
* @class vtkInteractorStyleRubberBand3D
* @brief A rubber band interactor for a 3D view
*
*
* vtkInteractorStyleRubberBand3D manages interaction in a 3D view.
* The style also allows draws a rubber band using the left button.
* All camera changes invoke StartInteractionEvent when the button
* is pressed, InteractionEvent when the mouse (or wheel) is moved,
* and EndInteractionEvent when the button is released. The bindings
* are as follows:
* Left mouse - Select (invokes a SelectionChangedEvent).
* Right mouse - Rotate.
* Shift + right mouse - Zoom.
* Middle mouse - Pan.
* Scroll wheel - Zoom.
