Which basis to choose

[smoothclear]

Hi,

Could I ask a question about the local orthogonal reference system for each triangle? I noticed that in the main.cpp, "igl::local_basis" is used to compute the basis for each triangle mesh. In the tutorial_nrosy.cpp, the local system is computed directly from the edge of the mesh. So a little bit confused which method we should use or both are OK?

Thanks a lot.

Hi,

As long as there's a basis, it's fine. So both method would work and I think they should have implemented the same thing.

Got that. Thanks.
