Detailed Description

vtkWidgetRepresentation for a poly line.

vtkPolyLineRepresentation is a vtkCurveRepresentation for a poly line. This 3D widget defines a poly line that can be interactively placed in a scene. The poly line has handles, the number of which can be changed, plus the widget can be picked on the poly line itself to translate or rotate it in the scene. Based on vtkCurveRepresentation

virtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkCurveRepresentation.

void vtkPolyLineRepresentation::GetPolyData ( vtkPolyData * pd )

virtual

Grab the polydata (including points) that defines the poly line.

polydata consists of points and line segments between consecutive points. Points are guaranteed to be up-to-date when either the InteractionEvent or EndInteraction events are invoked. The user provides the vtkPolyData and the points and polyline are added to it.

Implements vtkCurveRepresentation.

virtual void vtkPolyLineRepresentation::SetNumberOfHandles ( int npts )

virtual

Set the number of handles for this widget.

Implements vtkCurveRepresentation.

virtual vtkDoubleArray* vtkPolyLineRepresentation::GetHandlePositions ( )

double vtkPolyLineRepresentation::GetSummedLength ( )

virtual

Get the true length of the poly line.
