Detailed Description

Contour interpolator for placing points on an image.

vtkDijkstraImageContourLineInterpolator interpolates and places contour points on images. The class interpolates nodes by computing a graph laying on the image data. By graph, we mean that the line interpolating the two end points traverses along pixels so as to form a shortest path. A Dijkstra algorithm is used to compute the path.

The class is meant to be used in conjunction with vtkImageActorPointPlacer. One reason for this coupling is a performance issue: both classes need to perform a cell pick, and coupling avoids multiple cell picks (cell picks are slow). Another issue is that the interpolator may need to set the image input to its vtkDijkstraImageGeodesicPath ivar.

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkContourLineInterpolator.

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 vtkContourLineInterpolator.

◆ InterpolateLine()

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

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.

◆ SetCostImage()

virtual void vtkDijkstraImageContourLineInterpolator::SetCostImage ( vtkImageData * )

virtual

Set the image data for the vtkDijkstraImageGeodesicPath. If not set, the interpolator uses the image data input to the image actor. The image actor is obtained from the expected vtkImageActorPointPlacer.

◆ GetCostImage()
