[vtkusers] UnstructuredGrid to Graph

[David Doria]

I am trying to convert all of the edges in an vtkUnstructuredGrid to a vtkGraph.

Here is what I have come up with:
http://www.rpi.edu/~doriad/VTK_List/UnstructuredGridToGraph/

It seems to be horribly slow. Can anyone recommend a faster way to do this?

Thanks,

David
