[vtkusers] two scalars for a single unstructured grid??

[Berk Geveci]

You can simply add another scalar array with

foo->SetName("my scalar");
uGrid->GetPointData()->AddArray(foo);

The attributes are merely for convenience - they are treated like any other
array. Most filters have methods to select any arbitrary array by name. It
is usually something like SetInputArrayToProces(...) for filters.
