vtkOrientedPolygonalHandleRepresentation3D

Section: Visualization Toolkit Widget Classes

# Usage

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.

To create an instance of class vtkOrientedPolygonalHandleRepresentation3D, simply invoke its constructor as follows

      obj = vtkOrientedPolygonalHandleRepresentation3D
