[vtkusers] display vtkUnstructuredGrid edges as tubes

[Gerd Meiser]

Hello!
I am looking for a simple way to display the edges of a vtkUnstructuredGrid as tubes without iterating over each of the grid lines.

If the grid were not a vtkUnstructuredGrid, but generated by a vtkCubeSource instead, I can get the tubes with the following pyhton code:

CubeModel = vtk.vtkCubeSource()
[...]
Edges = vtk.vtkExtractEdges()
[...]
Edges.SetInputConnection(CubeModel.GetOutputPort())
Tubes = vtk.vtkTubeFilter()
Tubes.SetInputConnection(Edges.GetOutputPort())

Is there a way to use somthing similar to vtkExtractEdges() and vtkTubeFilter() on a vtkUnstructuredGrid?

Thank you
G. Meiser
