CGAL 4.3 - Triangulated Surface Mesh Simplification
|
The concept EdgeProfile
describes the requirements for a data structure that caches the local topology and geometry in the surroundings of an undirected edge.
This profile is used by the stop, cost and placement policies.
Types | |

edge_descriptor | v1_v0 () const |
The other directed edge corresponding to the undirected edge being collapsed. | |
Point const & | p0 () const |
The point of vertex v0 . | |
Point const & | p1 () const |
The point of vertex v1 . | |
vertex_descriptor | vL () const |
If v0v1 belongs to a finite face (is not a border edge) the third vertex of that triangular face, a null descriptor otherwise. | |
