[vtkusers] vtkPolyData

[Christos Panagiotou]

Hi all

I am trying to manipulate a 3D object that has been created by reading 
multiple 2D slices.

The object can be retrieved as a vtkPolyData object. Can someone explain 
to me how this object can be manipulated? Is there anyway to retrieve 
the 3-dimensional matrix with the points of the object and their values?

i would be greatful for any help
thanks
