|
|
*
|
|
* The vtkDistanceRepresentation2D is a representation for the
|
|
* vtkDistanceWidget. This representation consists of a measuring line (axis)
|
|
* and two vtkHandleWidgets to place the end points of the line. Note that
|
|
* this particular widget draws its representation in the overlay plane, and
|
|
* the handles also operate in the 2D overlay plane. (If you desire to use
|
|
* the distance widget for 3D measurements, use the
|
|
* vtkDistanceRepresentation3D.)
