Is anyone aware of any utility to generate and dump Principal, Gaussian and Mean Curvatures for a 3D Model or a set of points? I have reserched following tools -

meshlab cloudcompare They are able to compute the curvatures, but they do not have the option to dump it.

I need to get this information for my dataset which consists of like 200 models and would need to dump the curvature info for the same.

I would appreciate if anyone can help me on this.

    See (117884), (127975) -- is this even a question about the software product, Wolfram Mathematica? – Michael E2 Aug 13 '20 at 02:54
  • Welcome to Mathematica.SE. Are you sure you are posting on the right site? There is nothing in your question making it clear that it is concerned with Mathematica software. – m_goldberg Aug 13 '20 at 03:26
  • @m_goldberg - I am not sure if I am asking the question in write forum. I am have posted the same question in the main stackoverflow site, but haven't received any response.

    I posted here, thinking there might be any mathematical library or software, which can help me dump the curvatures at each point of a 3D mesh.

    I am all for making the comunity better, so let me know if I should take down the question from here.

  • Try ResourceFunction["GaussianCurvature"][surf[u, v], {u, v}] with 3D-surface surf[u,v] . – Ulrich Neumann Aug 13 '20 at 07:24
  • ResourceFunction["MeanCurvature"][surf[u, v], {u, v}] with 3D-surface surf[u,v] – Ulrich Neumann Aug 13 '20 at 07:31
