[vtkusers] curvature

[<bourouis.sami@voila.fr]

 I have an polydata surface 
 How can I compute the curvature for each point (triangle vertex) from
 the polydata ?
 Curvature means min and max curvature and /or gaussian curvature.
 
 the problem is:
 I started by using this,
 this is a pseudo code :
vtkCleanPolyData *cleaner=vtkCleanPolyData::New();
vtkCurvatures *curve1=vtkCurvatures::New();
     curve1->SetInput(cleaner->GetOutput());
     curve1->SetCurvatureTypeToGaussian();
vtkCurvatures *curve2=vtkCurvatures::New();
     curve2->SetInput(cleaner->GetOutput());
     curve2->SetCurvatureTypeToMean();


How can I save each point in the polydata and its values of curvatures ( curve1 and curve2 ) in any file ( eg. *.txt)



Thanks,
