[Paraview] xmdf question, vector and raw binary data

[David E DeMarle]

I think the JOIN function is supposed to allow that:
From:http://www.xdmf.org/index.php/XDMF_Model_and_Format
See:
    <DataItem ItemType="Function"
        Function="JOIN($0 , $1, $2)">
        <DataItem Reference="/Xdmf/DataItem[1]" />
        <DataItem Reference="/Xdmf/DataItem[2]" />
        <DataItem Reference="/Xdmf/DataItem[3]" />
    </DataItem>

But I had trouble using that when I tried long ago and resorted to
using the calculator filter to do the corresponding thing after the
read. (field1*iHat+field2*jHat+field3*kHat).
