Winged-Edge Mesh⇨ The original mesh structure to store connectivityinformation⇨ As the name implies, the focus is the edge Each vertex stores a pointer to one of the edges“radiating” from it Each polygon stores a pointer to one of its edges Each edge has 8 pointers: Pointers to each of its vertices (2) Pointers to each of its polygons (2) Pointers to each of its connecting edges (4)© Copyright Ian D.
