<DIV>I post you the code i used:</DIV>
<DIV> </DIV>
<DIV>vtkCurvatures *curve = vtkCurvatures::New();</DIV>
<DIV>curve->SetInput(cleaner->GetOutput());<BR>curve->SetCurvatureTypeToMaximum();<BR>curve->Update();</DIV>
<DIV> </DIV>
<DIV>vtkPolyDataMapper *maxMapper = vtkPolyDataMapper::New();<BR>maxMapper->SetInput(curve->GetOutput());<BR> <BR>vtkActor *maxCurve = vtkActor::New();<BR>maxCurve->SetMapper(maxMapper);<BR>maxCurve->SetPosition(0.0,0.0,0.0);<BR>myRender->AddActor(maxCurve);<BR>myRenderWindow->Render();</DIV>
<DIV> </DIV>
<DIV>Please, tell me where to add the code you sent to me to display the maximum curvatures>0.5</DIV>
<DIV> </DIV>
<DIV>Thank you for your help!!!</DIV>

Then pass the output of that filter to a vtkThreshold, using the
ThresholdByUpper method to indicate the values to keep. Example c++ code
is shown below.
vtkCurvatures *curv = vtkCurvatures::New();
curv->SetCurvatureTypeToMaximum();
vtkThreshold *thresh = vtkThreshold::New();
thresh->SetInputConnection(curv->GetOutputPort());
thresh->ThresholdByUpper(0.5); // using the example value you provided.
Online documentation for vtkCurvatures is here:

Online documentation for vtkThreshold is here:
