Detailed Description

vtkWidgetRepresentation base class for a widget that represents an curve that connects control points.

Base class for widgets used to define curves from points, such as vtkPolyLineRepresentation and vtkSplineRepresentation. This class uses handles, the number of which can be changed, to represent the points that define the curve. The handles can be picked can be picked on the curve itself to translate or rotate it in the scene.
