iterator over vtkLabelHierarchy
virtual void Next()
Advance the iterator.
virtual void SetTraversedBounds(vtkPolyData *)
Sets a polydata to fill with geometry representing the bounding boxes of the traversed octree nodes.
virtual void SetHierarchy(vtkLabelHierarchy *h)
The hierarchy being traversed by this iterator.
virtual void GetPoint(double x[3])
Retrieves the current label location.
virtual void BoxNode()
Add a representation to TraversedBounds for the current octree node.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual vtkStdString GetLabel()
Retrieves the current label string.
virtual void GetNodeGeometry(double ctr[3], double &size)=0
Retrieve the coordinates of the center of the current hierarchy node and the size of the node.
virtual bool IsAtEnd()
