[vtkusers] Nonlinear scaling of vtkPolyData

Hello,
I need to apply a nolinear scaling to my polydata.
Like in a *Fig. B* ,instead of Fig.A 
(Sorry, I am not that good at drawing, but let's presume that these figures
are cylinders and a cone)

What is the best VTK way to achieve that?

*What I have tried:*
 I tried to break my data into strips using vtkStripper and then to apply a
different scale value to each strip, and then apply a new points' values to
an original polydata.

It was not smooth and very slow. 
If it matters, my polydata  will always have between 10,000 to 20,000
vertices, it will never be larger.
Thanks,
AC
