vertex_descriptor

ep.v0 ()

One of vertices of the edge to be collapsed.

vertex_descriptor

ep.v1 ()

The other vertex of the edge to be collapsed.

edge_descriptor

ep.v0v1 ()

One of the directed edges corresponding to the undirected
edge being collapsed.

edge_descriptor

ep.v1v0 ()

The other directed edge corresponding to the undirected
edge being collapsed.

Point

ep.p0 ()

The point of vertex $$v0.

Point

ep.p1 ()

The point of vertex $$v1.

vertex_descriptor

ep.vL ()

If $$v0v1 belongs to a finite face (is not a border edge)
the third vertex of that triangular face, a null descriptor otherwise.

edge_descriptor

ep.v1vL ()

If $$v0v1 belongs to a finite face (is not a border edge)
the directed edge from $$v1 to $$vL, a null descriptor otherwise.

edge_descriptor

ep.vLv0 ()

If $$v0v1 belongs to a finite face (is not a border edge)
the directed edge from $$vL to $$v0, a null descriptor otherwise.

vertex_descriptor

ep.vR ()

If $$v1v0 belongs to a finite face (is not a border edge)
the third vertex of that triangular face, a null descriptor otherwise.

edge_descriptor

ep.v0vR ()

If $$v1v0 belongs to a finite face (is not a border edge)
the directed edge from $$v0 to $$vR, a null descriptor otherwise.

edge_descriptor

ep.vRv1 ()

If $$v1v0 belongs to a finite face (is not a border edge)
the directed edge from $$vR to $$v1, a null descriptor otherwise.

std::vector<vertex_descriptor>

ep.link ()

The unique sequence of the vertices
around $$v0v1 in topological order (ccw or ccw depending
on the relative ordering of v0 and v1 in the profile).

std::vector<edge_descriptor>

ep.border_edges ()

The unique collection of the border directed edges incident upon $$v0 and $$v1.

bool

ep.left_face_exits ()

Indicates if v0v1 belongs to a finite face of the mesh (i.e, v0v1 is not a border edge).

bool

ep.right_face_exits ()

Indicates if v0v1 belongs to a finite face of the mesh (i.e, v1v0 is not a border edge).
