[vtkusers] Fwd: Choose the second component in vtkDataArray without copy

[mirko heuegger]

Hello!

A Other Question, how are you trying to read the vectorData?

And what is the return from reader->GetNumberOfVectorsInFile() (the
reader-object should be something like a vtkDataSetReader)?


regards

mirko
