<div>Hello guys,</div>
<div> </div>
<div>I am using the vtkCurvatures of VTK 5.0. I notice that it calculate the mean curvature by dividing the sum of weighted edges with the number of neighboring edges around current vertex. But according to the papers: N. Dyn, etc's "Optimizing 3d triangulations using discrete curvature analysis" and Gady Agam etc's "A sampling framework for accurate curvature estimation in discrete surfaces", the sum should be only divided by a constant of 4. Can anyone give me any explanation for that? I am very new to this field.
