Single item of the structure that track the state of the current algorithm. This structure contains a polygon stored as a list of point and edges. It also embbed information about neighbor edge, neighbor face, and if the current point is a point of the polyhedron.

| integer | point_id = 0 | 
|  | Corresponding point number in the polyhedron structure. 0 if the point is not on the polyhedron.

|  | 
| integer | edge = 0 | 
|  | If point_id == 0, contains the edge number in the polyhedron structure. edge = 0 if point_id ≠ 0. 
 | 
|  | 
| integer | face = 0 | 
|  | Contains the face number in the polyhedron structure that lies between this item and the next.
