[vtkusers] How to delete cells from vtkPolyData

[Hualiang Zhong]

Hi all,

I am wondering anybody know how to delete a cell from vtkPolyData?
Its DeleteCell(i) method only marks the cell type as VTK_EMPTY_CELL, but I still don't know how to really remove the cell from the polydata before I visualize it.

Thanks for all sugestions!
