Render Cell Scalars from vtkXMLPolyData?

Changed my table code to mimic your C++ example, and still don’t get coloring. :frowning:

    ctf = vtkColorTransferFunction()
    ctf.SetColorSpaceToRGB()
    ctf.AddRGBPoint(0, 1.0, 0.0, 0.0)
    ctf.AddRGBPoint(MAX_RADIANCE, 0.0, 1.0, 1.0)

    lut = vtkLookupTable()
    lut.SetNumberOfTableValues(TABLE_SIZE)
    for i in range(TABLE_SIZE):
        rgb = ctf.GetColor(i/TABLE_SIZE)
        lut.SetTableValue(i, *rgb)
    lut.SetRampToLinear()
    lut.Build()
