// .NAME vtkOrientedPolygonalHandleRepresentation3D - represent a user defined handle geometry in 3D while maintaining a fixed orientation w.r.t the camera.
// .SECTION Description
// This class serves as the geometrical representation of a vtkHandleWidget.
// The handle can be represented by an arbitrary polygonal data (vtkPolyData),
// set via SetHandle(vtkPolyData *). The actual position of the handle
// will be initially assumed to be (0,0,0). You can specify an offset from
// this position if desired. This class differs from
// vtkPolygonalHandleRepresentation3D in that the handle will always remain
// front facing, ie it maintains a fixed orientation with respect to the
// camera. This is done by using vtkFollowers internally to render the actors.
// .SECTION See Also
