[vtkusers] vtkGraphToTable

[Wylie, Brian]

Hi JB,

I think you could do something like...

vtkRandomGraphSource->vtkGraphLayout->vtkDataObjectToTable->vtkDelimitedTextWriter


Parameters to vtkDataObjectToTable allow you to specify if you want to make a table off edges, vertices, or whatever...

# Cleave off part of the graph
vertexDataTable = vtkDataObjectToTable()
vertexDataTable.SetInputConnection(graphLayout.GetOutputPort())
vertexDataTable.SetFieldType(3) # Vertex data

Greetings,

May I have your advice in best approach for a use case of converting GraphLayout coordinates to a vtkTable.  For example,

vtkRandomGraphSource->vtkGraphLayout->vtkTable

where vtkTable is based on four columns  (id and 3d coordinates):

vertexId, X, Y, Z

I would be very appreciative for any suggestions to create this "vtkGraphToTable" functionality.

Cheers,

JB
