Let hnew be h->next()->opposite() after the split, i.e., a halfedge of the new edge. The split regroups the halfedges around the two vertices.

WebA silhouette edge (in your context) is defined by its neighboring facets having one upwards and one downwards normal (i.e., one positive normal z-coordinate and one negative). This can be checked using Polyhedron_traits_with_normals_3 or you can compute the normals yourself on-the-fly.

The edges are traversed … Webhalfedges is a border halfedge. A surface is closedif it contains no border halfedges. A closed surface is a boundary representation for polyhedrons in three dimensions. The convention is that the halfedges are oriented counterclockwise around facets as seen from the outside of the polyhedron. An implication is that the
