[Paraview] (no subject)

[Sebastien Jourdain]

Here is the script that you should run

from paraview.simple import *

data = XMLPolyDataReader( FileName=['/.../file.vtp'] )

smooth = Smooth(data)
smooth.NumberofIterations = 200

writer = CreateWriter("foo.ply", smooth)
writer.FileType = 'Ascii'
writer.UpdatePipeline()
