Hi there Kent, thanks for answering!

I should have shown more of the VTI file:
     <PointData Vectors="velocity">
        <DataArray type="Float32" Name="velocity"
NumberOfComponents="3" format="appended" offset="0"           />
      </PointData>

That's very definitely point data.   As far as the ParaView interface
is concerned, it also seems to be point data: when I select this
dataset, the "Cell data to point data" filter is DISABLED and the
"Point data to cell data" is ENABLED.

Any other ideas?

Thanks,
Charl
