This script "CalculCurvature.py" is a deduction of Rusinkiewicz's paper for curvature estimation . In our case we don't go far to derivatives.
Paper : Estimation of curvatures and their derivatives on triangle Meshes by Rusinkiewicz
You need only numpy module to run the script "CalculCurvature.py", while to run examples, you need also trimesh to work with triangular meshes and matplotlib to do the Delaunay triangulation.
Trimesh is an open source python module dedicated to general mesh processing using only triangular mesh : https://github.com/mikedh/trimesh
Requirements :
Trimesh
User installation
If you already have a working installation of trimesh ,
the easiest way to install trimesh is using pip
::
pip install trimesh
or conda
::
conda install trimesh
The documentation includes more detailed installation instructions <https://trimsh.org/trimesh.html>
