[vtkusers] Cell Data

[Benjamin Schindler]

Hi 

I've got an unstructured grid and I would like to extract the data
inside a given box using vtkUnstructuredGridGeometryFilter. However, no
data is coming out, because the ensight readers don't produce cell
data. 

So, why does the ensight reader not produce cell data and is there some
filter to produce it?

Thanks
