[vtkusers] principal directions of curvature

[Syrkina Ekaterina]

Hello,

what is the easiest way to access curvature tensor for 3d triangular
mesh surface? I need principal directions and curvatures plus normal
calculated for every point. I found some old message about
vtkCurvatureTensor class:
http://www.vtk.org/pipermail/vtkusers/2005-July/080632.html -- is it
maybe already available in VTK as a part of some other class?
vtkCurvatures doesn't seem to provide this functionality.

Thanks. Best,
Katya
