Smoothing poly data in VTK

Question

I have a poly data that looks like this:

What I want to obtain is something that would be smoother, something like this (edited in paint for demonstration purpose):

So far I've tried the following filters:

• vtkWindowedSincPolyDataFilter
• vtkSmoothPolyDataFilter

However, the closest I got was with the first one, with a result like this:

Is there any filter or strategy in VTK that would allow me to reach something really close to the second picture?

Thanks in advance.

Answer 1

I suggest you play with the convergence and iterations parameter of vtkSmoothPolyDataFilter to achieve the optimal result for a single application of that filter. If this is not satisfying, why don't you go ahead and apply it multiple times, one after the other? This is what I would do if I had this problem at my hands.
