[vtkusers] cellClipping for vtkGeometryFilter

[Pan, Tony C (CRD)]

Marc,
SetCellClipping takes a boolean value (in the case of C++, 0 for false and 1 for true), not a cell
id.  It has the same function as CellClippingOn and CellClippingOff.  So, in your code, you've turned
cell clipping off, then back on.  If you want to prevent the cell from being clipped, then removing
the line CellClippingOn should do the trick.

This kind of syntax is prevalent in vtk API.  There are a lot of functions that have the On/Off form
with a corresponding Set form which takes a boolean argument.

Subject: [vtkusers] cellClipping for vtkGeometryFilter


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.
