[vtkusers] cellClipping for vtkGeometryFilter

[Marc Niethammer]

Hi,

I am trying to prevent the GeometryFilter from converting
individual cells by using SetCellClipping cellID.
However, the following code seems to have no effect at all.
(sPts are vtkStructuredPoints here).

vtkGeometryFilter gf
gf SetCellClipping 0
gf CellClippingOn
gf SetInput sPts

Does anybody have an idea what that is?
(Did I misunderstand the meaning of SetCellClipping?)

Thanks.
