calculate angle between the gradient of the Fielder vector and the principal directions of curvatures
Fielder vector is the first non constatn eigen-function of the Laplace Beltrami operator applied to the mesh
angle distribution comparison to uniform angle distribution using KullBack Lieber divergence
Remarks from @JulienLefevreMars :
We should be careful about what is the reference uniform angle distribution over a mesh.
Hence, we could consider doing random rotations over the mesh to see how the angles evolves
On a different level, we should spent extra care about the citations and authors involved.
Aim
We could include the Principal Directions of Curvatures Analysis Framework introduced in https://www.nature.com/articles/s41598-021-87124-y.
Framework in a nutshell:
