You can use the range provided by halfedges_around_faces():

Hi,

I need the edges info for specific faces. How I can iterate over edges of
the faces. Like here it can iterate over vertices of the faces.

int i=0;
BOOST_FOREACH(face_descriptor f, faces(surface_mesh)){
int j=0;
CGAL::Vertex_around_face_iterator<Surface_mesh> vbegin, vend;
for(boost::tie(vbegin, vend) =
vertices_around_face(surface_mesh.halfedge(f), surface_mesh);
vbegin != vend;
++vbegin){
j++;
std::cout << j << "th index of " << i << "th face: "<< *vbegin <<
std::endl;
}
i++;
}

how to iterate over edges?

Shrabani Ghosh
