Detailed Description

Doubly connected triangle list.

DList is used to implement:

  • the stack S of triangles to flip in insert()
  • the queue Q of intersected edges in detect_intersected_edges() and constrain_edges()
  • the list N of new edges in constrain_edges() Everything is stored in CDBase vectors Tnext_, Tprev_ and Tflags_. As a consequence, the same triangle can be only in a single DList at the same time.

Constructor & Destructor Documentation

◆ DList() [1/2]

GEO::CDTBase2d::DList::DList ( CDTBase2d &  cdt,
index_t  list_id 
)
inline

Constructs an empty DList.

Parameters
[in]cdta reference to the CDTBase2d
[in]list_idthe DList id, in 0..DLIST_NB-1

Definition at line 424 of file CDT_2d.h.

◆ DList() [2/2]

GEO::CDTBase2d::DList::DList ( CDTBase2d &  cdt)
inline

Creates an uninitialized DList.

One cannot do anything with an uninitialized Dlist, except:
