OpenMesh Random Access

I thought OpenMesh would support random access to faces edges vertices. All I can find are iterators and circulators: for( auto v : mesh->vertices() ) mesh->point(v).data(); How can I do something like this: mesh->vertices(42);

Do OpenMesh circulators guarantee a specific order?

OpenMesh provides circulators to iterate over neighboring elements. The FaceVertex iterator is an example, which iterates over the vertices of a given face. My question is, does this circulator provide a specific, reproducible order of the face's…

Are OpenMesh iterators changed when adding elements?

Do existing OpenMesh iterators change, when I add elements? Example code: auto vh1 = mesh.vertex_handle(0); auto vh2 = mesh.vertex_handle(1); auto vh3 = mesh.vertex_handle(2); for(auto fh: mesh.faces()) { mesh.add_face(vh1, vh2, vh3); } I did…

OpenMesh skipping circulators

OpenMesh has its skipping iterators which skips elements marked for deletion. Is there an equivalent in circulators? I'm thinking circulators which treat mesh elements marked deleted as if they were not there any more. Note that this is not as…
