[vtkusers] Cannot access to functions in vtkCurvatures class!!!

[B. C.]

Good evening everybody.
I'm using vtkCurvatures class to extract curvatures from a polydata object. I'm refering to 'VTK vtkCurvatures Class Reference.mht'
 
When i try to extract maximum curvatures using 'GetMaximumCurvature' , i have this error message:
'GetMaximumCurvature' : is not a member of 'vtkCurvatures'

And, when i try to extract mean curvatures using 'GetMeanCurvature' , i have this error message:
'GetMeanCurvature' : cannot access protected member declared in class 'vtkCurvatures'

What should i do for each case??
 
Thank you so much
