[vtkusers] Extract cells that contain all of selected points

[soheilghafurian]

Hi everyone!

I am extracting a part of a mesh by selecting the points I want and using
vtkSelectionNode. The problem is that I want only those cells in which all
of the points are selected, but selectionNode returns also cells which have
at least one of the selected points, because I use

selectionNode->GetProperties()->Set(vtkSelectionNode::CONTAINING_CELLS(),
1);

If I don't use this line, the cells are not extracted and I will have only
points, however I want a surface.

Does anyone know how I should extract the cells in which all of the points
are selected?

Thanks a lot
