[vtkusers] question on vtkPolydataNormals

[niccolo.camarlinghi at pi.infn.it]

Dear all,

I'm a not a good vtk user so please forgive me if i'm asking a stupid
question.
I'm trying to use the normals computed by vtkPolydataNormals.

My aim is to obtain a correspondence between the coordinates of a  point
and its normal , i.e. point x,y,z normal nx,ny,nz and so on.. 
I was able to access to all the normals  using
GetPointData()->GetNormals() but i cannot figure out how to access to
the corresponding point coordinates.  
 
Best Regards
