/**
* @class vtkInteractorStyle3D
* @brief extends interaction to support 3D input
*
* vtkInteractorStyle3D allows the user to interact with (rotate,
* pan, etc.) objects in the scene indendent of each other. It is designed
* to use 3d positions and orientations instead of 2D.
*
* The following interactions are specified by default.
*
* A click and hold in 3D within the bounding box of a prop
* will pick up that prop allowing you to translate and
* orient that prop as desired with the 3D controller.
*
* Click/dragging two controllers and pulling them apart or
* pushing them together will initial a scale gesture
* that will scale the world larger or smaller.
*
* Click/dragging two controllers and translating them in the same
* direction will translate the camera/world
* pushing them together will initial a scale gesture
* that will scale the world larger or smaller.
*
* If a controller is right clicked (push touchpad on Vive)
* then it starts a fly motion where the camer moves in the
* direction the controller is pointing. It moves at a speed
* scaled by the position of your thumb on the trackpad.
* Higher moves faster forward. Lower moves faster backwards.
*
* For the Vive left click is mapped to the trigger and right
* click is mapped to pushing the trackpad down.
