<br>
Is there something like vtkPolyDataToGraph which does the inverse of vtkGraphToPolyData?<br>
If not, how could this be implemented for vtkPolyData that represents a graph/tree (e.g. vtkPolyData that resulted from vtkGraphToPolyData)?<br>
Is there already some iterator that could be used to iterate over the points in a back-tracking fashion?<br>
<br>
Many thanks for any help or hints<br>
