WebA Minimal Halfedge Data Structure. The following program defines a minimal halfedge data structure using the minimal items class CGAL:: HalfedgeDS_min_items and a list-based halfedge data structure. The result is a data structure maintaining only halfedges with next and opposite pointers. No vertices or faces are stored.
