Define Documentation

#define forall_face_adj	(	adj,
		f		)	for((adj)=(f)->firstAdj(); (adj); (adj)=(f)->nextFaceEdge(adj))

Iteration over all adjacency entries adj of the face f.

A faster version for this iteration demonstrates the following code snippet:

   adjEntry adj1 = f->firstAdj(), adj = adj1;
   do {
       ...
       adj = adj->faceCycleSucc();
   } while (adj != adj1);

#define forall_faces	(	f,
		E		)	for((f)=(E).firstFace(); (f); (f)=(f)->succ())

Iteration over all faces f of the combinatorial embedding E.

#define forall_rev_faces	(	f,
		E		)	for((f)=(E).lastFace(); (f); (f)=(f)->pred())

Iteration over all faces f of the combinatorial embedding E (in reverse order).
