[vtkusers] How to programatically force a redraw after changing my vtkPlaneSource's centre?

[Sean McBride]

Hi all,

Easy newbie question. :)

I have a vtkPlaneSource and I want to move it in response to user
input.  vtkPlaneSource's SetCenter is perfect and indeed works.  The
only problem is that the change is not visible until i use the mouse to
(slightly) rotate my scene.  How do I programatically tell the vtk
system that it needs to redraw?  I have tried calling Update() on the
vtkPlaneSource and its associated vtkPolyDataMapper, but that does not help.

Thanks!
