|
|
*
|
|
* The vtkAngleRepresentation3D is a representation for the
|
|
* vtkAngleWidget. This representation consists of two rays and three
|
|
* vtkHandleRepresentations to place and manipulate the three points defining
|
|
* the angle representation. (Note: the three points are referred to as Point1,
|
|
* Center, and Point2, at the two end points (Point1 and Point2) and Center
|
|
* (around which the angle is measured). This particular implementation is a
|
|
* 3D representation, meaning that it draws in the overlay plane.
