The class Ridge_line<TriangulatedSurfaceMesh> stores the description of a ridge line. The list of halfedges defines a connected sequence of edges (but not as oriented halfedges). The scalar b paired with a halfedge pq is the barycentric coordinate of the crossing point r with the ridge : r = b × p + (1-b) × q.
