That's what I'd like to do, but I'm not sure what would be the correct
syntax in this case. There is an example of using a polyline as sharp
feature for 3D mesh, but no example for surface mesh. Also, is it
possible to use the detect_features() for a surface mesh just like it
was used for 3D mesh in mesh_polyhedral_domain_with_features.cpp
example, particularly when the surface is defined by an implicit
function? Thanks for any help!
