[vtkusers] about vtkDijkstraGraphGeodesicPath

[Frédéric BRIEND]

Hi,

Sorry for the double post.
Since the old post of Karthik 
<https://public.kitware.com/pipermail/vtkusers/2010-May/060254.html>, is 
there a way with "vtkDijkstraGraphGeodesicPath" to have the distance by 
GetGeodesicLength() ? How to do otherwise?

Thanks in advance!

My python script:

cylinder= vtk.vtkSphereSource()
cylinder.SetCenter(0.0, 0.0, 0.0)
cylinder.SetRadius(0.5)

dijkstra = vtk.vtkDijkstraGraphGeodesicPath()
dijkstra.SetInputConnection(cylinder.GetOutputPort())
dijkstra.SetStartVertex(4)
dijkstra.SetEndVertex(28)
dijkstra.Update()

weights = vtk.vtkDoubleArray()
size=dijkstra.GetCumulativeWeights(weights)

print size

I obtain for size: none
