// .NAME vtkPolygonalHandleRepresentation3D - represent a user defined handle geometry in 3D space
// .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.
// .SECTION See Also
// vtkPointHandleRepresentation3D vtkHandleRepresentation vtkHandleWidget
