@JacquesOlivierLachaud there is an issue with tangent_explorer due to a deprecated API use. Could you please have a look?

I don't know if this is related to this PR but dgtalCalcuus-halfsphere only returns a zero value map.

Apparently, polyscope SurfaceMesh does not expose any more faces and edges (when I look at surface_mesh.h). So the only way to correct the code is to memorise the vector of faces of the primal surface at construction.

Self-merging this one.
