Hi Thorsten,
You need to have tensor data, e.g. curvature tensors or whatever...
for your grid or image, you would call:
grid->GetPointData()->SetTensors(data)
where data is a vtkDataArray, e.g. of type double, with 9 components (
the three rows of the 3x3 tensor). I don't know what happens if there
are fewer components.
There is an example data set in the VTK Data called "tensors.vtk".
http://www.vtk.org/files/release/5.4/vtkdata-5.4.2.tar.gz
Or my own simple data here:

Cheers

Thank you very much, this sounds like what I need.
The code compiles and runs fine (which means, it doesnt
crash ParaView upon loading). The remaining question
is, what would the correct input data be?
Best regards,
Thorsten
