[ITK] [ITK-users] itkSmoothingQuadEdgeMeshFilter Help!!

[Mallikarjun K]

Hi Bill,
Thanks for the replay.

Yes,I built both ITK and my app with Release ,I forgot to mention it in the
previous post.Actually the data set is the output of
vtkDiscreteMarchingCubes algorithm(around 5MB) and need to smooth .I saved
this marching cube's output as .vtk file and read it
using itkVTKPolyDataReader and then I am giving this reader's output to
itkSmoothingQuadEdgeMeshFilter's input.

I checked the execution time of each step in the pipeline ,after
SmothingQEMeshFilter has got it's input ,it is taking time to process the
data.

Thank you
