I tried using these filters but for some reason I am not getting any change 
in the output, my code is:

vtkSmoothPolyDataFilter *Smooth = vtkSmoothPolyDataFilter::New();

Then I tried :
vtkWindowedSincPolyDataFilter *Smooth=vtkWindowedSincPolyDataFilter::New();

And still no change, Any Ideas why this is happening??
Thanks in Advance...

P.S Thanks Mathieu
