virtual int vtkPolyDataContourLineInterpolator::InterpolateLine	(	vtkRenderer *	ren,
		vtkContourRepresentation *	rep,
		int	idx1,
		int	idx2
	)

pure virtual

Subclasses that wish to interpolate a line segment must implement this.

For instance vtkBezierContourLineInterpolator adds nodes between idx1 and idx2, that allow the contour to adhere to a bezier curve.

Implements vtkContourLineInterpolator.

Implemented in vtkPolygonalSurfaceContourLineInterpolator.

virtual int vtkPolyDataContourLineInterpolator::UpdateNode	(	vtkRenderer *	,
		vtkContourRepresentation *	,
		double *	vtkNotUsednode,
		int	vtkNotUsedidx
	)

pure virtual

The interpolator is given a chance to update the node.

vtkImageContourLineInterpolator updates the idx'th node in the contour, so it automatically sticks to edges in the vicinity as the user constructs the contour. Returns 0 if the node (world position) is unchanged.

Reimplemented from vtkContourLineInterpolator.

Implemented in vtkPolygonalSurfaceContourLineInterpolator.

virtual vtkPolyDataCollection* vtkPolyDataContourLineInterpolator::GetPolys ( )
