[vtkusers] Point data with vtkUnstructuredGridReader

[Berk Geveci]

You need something like:

    reader->ReadAllScalarsOn();
    reader->ReadAllVectorsOn();
    reader->ReadAllNormalsOn();
    reader->ReadAllTensorsOn();
    reader->ReadAllColorScalarsOn();
    reader->ReadAllTCoordsOn();
    reader->ReadAllFieldsOn();

Translate to Python and adjust to taste.
