[vtkusers] Using vtkXMLStructuredGridReader to read only part of a data file

[Favre Jean]

I believe It is possible to select which array to load or skip over, before executing Update().

You must execute UpdateInformation() first, and then set or unset the arrays of your choice. Here is the example python code

reader = vtkXMLUnstructuredGridReader()
reader.SetFileName("/local/data/slice.vtu")
reader.UpdateInformation()

print reader.GetPointDataArraySelection()

reader.SetPointArrayStatus('Temperature', 0)
reader.GetPointArrayStatus('Temperature')

reader.Update()
