[vtkusers] vtkTubeFilter question

[Hal Schwab]

Hi All,
I have a vtkPolyData that contains a polyline. Each line
segment (cell) has scalar data attached. This is the
input to a vtkTubeFilter. How can I have the cell scalar data
of the input copied to the output cells. I tried CopyScalarsOn(),
but it had no effect. Thank you.
