[vtkusers] Is It Possible to Provide Only Data for A Part of Grid

[tdexplorer]

I have a relatively large unstructured grid which VTK renders slowly.  So I
decided to use vtkThreshold to extract a small portion of the grid and then
render only this part.  To speedup my program, I would also hope to provide
only cell attributte data to the extracted portion of the grid.  Is it
possible to do so. Thanks.
