Objects and Operators

The face methods are:

Hedge* Face::hedge(int i) // returns the i-th half-edge
Vertex* Face::vertex(int i) // returns the i-th vertex
Hedge* Face::split_hedge() // returns the split half-edge
Vertex* Face::weld_vertex() // returns the welding vertex
boolean Face::is_inbase() // returns true if the face is on the base mesh

The edge methods are:

 Hedge Edge::hedge(int i) // returns the i-th half-edge
 boolean Edge::is_boundary() // returns true if on boundary
 boolean Edge::is_split() // returns true if it is a split edge

The half-edge methods are:

 Vertex* Hedge::org() // returns the origin vertex
 Vertex* Hedge::dst() // returns the destination vertex
 Face* Hedge::face() // returns the incident face
 Edge* Hedge::edge() // returns the parent edge
 Hedge* Hedge::sym() // returns the mate half-edge
 Hedge* Hedge::prev() // returns the previous half-edge
 Hedge* Hedge::next() // returns the next half-edge

The vertex methods are:

 Hedge* Vertex::star_first() // first incident half-edge
 Hedge* Vertex::star_next(Hedge *e) // iterates to get the next half-edge
 Point* Vertex::level() // returns the level of the vertex

In addition to the mesh adaptation functions, the library also provides iterators for accessing the mesh elements:

 Iterator Mesh::face_iter() // returns face container iterator
 Iterator Mesh::edge_iter() // returns edge container iterator
 Iterator Mesh::vertex_iter() // returns vertex container iterator
