[vtkusers] vtkSmoothPolyDataFilter doesn't smooth much

[Fernando Pérez-García]

Dear VTK experts,

This is my first post here. I'm trying to smooth a mesh created from a
mask. I've tried different parameters but I don't get the result I want,
some vertices don't move at all!

I attach
​snaps from the
 original
​ mesh​
, the poor result I get from VTK and the one that's looks good, which I got
using the Laplacian filter in MeshLab.


This is my code:

reader = vtk.vtkPolyDataReader()

reader.SetFileName(meshInputPath)

reader.Update()


mesh = reader.GetOutput()


smoothFilter = vtk.vtkSmoothPolyDataFilter()

smoothFilter.SetNumberOfIterations(500)

smoothFilter.SetInput(mesh)

smoothFilter.Update()


writer = vtk.vtkPolyDataWriter()

writer.SetInput(smoothFilter.GetOutput())

writer.SetFileName(meshOutputPath)

writer.Write()


Do you know what I'm doing wrong?


Thank you,

Fernando
