[vtkusers] Transforming Data but not vtkActors ... (Please help !)

[Sebastien Auclair]

Hi !
This is really simple.

How are we suppose to modify something without operating on the vtkActor
?(i.e. Modifying the original data..polydata...)

Let say i wish to scale a previously created cube.(i.e. Created using
vtkCubeSource... to vtkActor3D)
I kept all the vtk instances as member variable of a CUBE class i made. (In
C++)
Now comes the scaling action...

How can i modify the dataSet (or PolyData) and update the drawing
accordingly. (Without recreating the pipeline of course !)

Thanks !
