[vtkusers] Help for using vtkCurvatures

I want to use vtkCurvatures to get the curvatures of a point cloud for each
point, but this point cloud is not a closed 3D surface, it seems
vtkCurvatures can not be used for the object of this type. Also I tried
vtkCurvatures by other objects, such as a vtkSphereSource, it is usable.

So does someone have any ideas if I want to get the curvatures of a point
cloud which is not a closed 3D surface ?

Thank you very much for your help!
