Hi.

From the CGAL manual about 3D triangulation, it said

"Each cell gives access to its four incident vertices and to its four adjacent cells. Each vertex gives direct access to one of its incident cells, which is sufficient to retrieve all the incident cells when needed."

"Edges ($$1-faces) and facets ($$2-faces) are not explicitly represented: a facet is given by a cell and an index (the facet i of a cell c is the facet of c that is opposite to the vertex of index i) and an edge is given by a cell and two indices (the edge (i,j) of a cell c is the edge whose endpoints are the vertices of indices i and j of c)."

May I ask if it is possible to get a facet handle from a cell handle? (i.e. the handle of the facet making up the cell)

From the CGAL manual, I can only find vertex handle from cell handle

Thanks
