Hi, Jana Sefcikova :<br><br>Thank you for your advice !<br><br>But I need to get the exact Gauss or Mean curvature. what do you think if I convert point cloud to a mesh, then use vtkCurvatures to get the curvature for each point ?<br>
<br>Also, I have another question. If I can get the curvatures, but how to get the curvature value for each point from vtkCurvatures ? Though I know some method like "curv->GetOutput()->GetPointData()->GetScalars()" to get the curvature values, but how can I know the coordinate (x, y, z) of that curvature value at the same time ?<br>

Hi , vtkCurvatures works with triangulated mesh, and ignores points and lines.<div>If you do not need exactly Gauss or Mean curvature, you could use vtkPointSetCurvatureEstimation algorithm presented here <a href="http://www.insight-journal.org/browse/publication/708/" target="_blank">http://www.insight-journal.org/browse/publication/708/</a> </div>
