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

void vtkPolyLineRepresentation::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

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 ( )

virtual

Get the positions of the handles.

Implements vtkCurveRepresentation.

double vtkPolyLineRepresentation::GetSummedLength ( )

virtual

Get the true length of the poly line. Calculated as the summed lengths of the individual straight line segments.

Implements vtkCurveRepresentation.

virtual void vtkPolyLineRepresentation::InitializeHandles ( vtkPoints * points )

virtual

Convenience method to allocate and set the handles from a vtkPoints instance. If the first and last points are the same, the poly line sets Closed to on and disregards the last point, otherwise Closed remains unchanged.

Implements vtkCurveRepresentation.

virtual void vtkPolyLineRepresentation::BuildRepresentation ( )

virtual

Build the representation for the poly line.

Implements vtkCurveRepresentation.
