[vtkusers] vtkLinearFilter doesn't work with the output of vtkWindowedSincPolyDataFilter

[Jothy]

Thanks, but I really don't understand why it does not work. Anyway, will
this dataSetSurfaceFilter preserve the holes inside the mesh. For instance,
if the mesh has a empty volume inside it (lung tumor which is not part of
the lung ).

I will try this and let you know.

Thanks again

Jothy
