// .NAME vtkSplineRepresentation - representation for a spline.
// .SECTION Description
// vtkSplineRepresentation is a vtkWidgetRepresentation for a spline.
// This 3D widget defines a spline that can be interactively placed in a
// scene. The spline has handles, the number of which can be changed, plus it
// can be picked on the spline itself to translate or rotate it in the scene.
// This is based on vtkSplineWidget.
// .SECTION See Also
// vtkSplineWidget, vtkSplineWidget2

// Grab the polydata (including points) that defines the spline. The
// polydata consists of points and line segments numbering Resolution + 1
// and Resolution, respectively. Points are guaranteed to be up-to-date when
// either the InteractionEvent or EndInteraction events are invoked. The

// Set the parametric spline object. Through vtkParametricSpline's API, the
// user can supply and configure one of two types of spline:
// vtkCardinalSpline, vtkKochanekSpline. The widget controls the open
// or closed configuration of the spline.

// Closed to the on InteractionState and disregards the last point, otherwise Closed
// remains unchanged.
