Detailed Description

abstract representation for a spline.

vtkAbstractSplineRepresentation is a vtkWidgetRepresentation for an abstract spline. This 3D widget defines a spline that can be accessed, set and configured. Deriving classes are then able to combine their own handles using this class.

PrintSelf()

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

overridevirtual

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 vtkObjectBase.

Reimplemented in vtkCameraPathRepresentation, and vtkSplineRepresentation.

GetPolyData()

void vtkAbstractSplineRepresentation::GetPolyData ( vtkPolyData *  pd )

overridevirtual

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 user provides the vtkPolyData and the points and polyline are added to it.

Implements vtkCurveRepresentation.

SetResolution()

void vtkAbstractSplineRepresentation::SetResolution

(

int

resolution

)

Set/Get the number of line segments representing the spline for this widget.

The default value is 499.

GetResolution()

virtual int vtkAbstractSplineRepresentation::GetResolution ( )

virtual

Set/Get the number of line segments representing the spline for this widget.

The default value is 499.

GetParametricSpline()

virtual vtkParametricSpline * vtkAbstractSplineRepresentation::GetParametricSpline ( )

virtual

Set the parametric spline object.

Can be redefined in the child classes for further updates when a spline is set. The default value is nullptr.

SetParametricSpline()

virtual void vtkAbstractSplineRepresentation::SetParametricSpline ( vtkParametricSpline *  spline )

virtual

Set the parametric spline object.

Can be redefined in the child classes for further updates when a spline is set. The default value is nullptr.

Reimplemented in vtkCameraPathRepresentation, and vtkSplineRepresentation.

GetHandlePositions()

vtkDoubleArray * vtkAbstractSplineRepresentation::GetHandlePositions ( )

overridevirtual

Get the position of the spline handles.

Implements vtkCurveRepresentation.

GetSummedLength()

double vtkAbstractSplineRepresentation::GetSummedLength ( )

overridevirtual

Get the approximate vs.

the true arc length of the spline. Calculated as the summed lengths of the individual straight line segments. Use SetResolution to control the accuracy.

Implements vtkCurveRepresentation.
