looks like the scalar values of the cells changes once you pass the data
through vtkThreshold. following might work. code is in java.
say "scalarValue" is the scalar values of the cells that were not removed.
vtkPolyData data = vtkthreshold.GetOutput();
vtkDataArray dataArray = data.GetCellData().GetScalars();
ask me if I am not clear

Subject: [vtkusers] vtkThreshold
I have been using a vtkThreshold filter to remove cells based upon their
cell data Scalars. When I do this the color mapping changes, more
specifically, if I remove cells < a value the cells with values = value
are now blue, I would like the cells that were not removed to maintain the
color mapping before the filter was used, is this possible/simple?
Thanks for your time,
