pmwx_cn.add_edge ( |
Traits::X_curve cv,
Planar_map::Halfedge_handle e,
bool original_direction,
bool overlap) |
|
| |
called each time a pair of twin halfedges is added to the planar map.
cv is the curve of the added halfedges.
e is one of the new halfedges.
original_direction is true iff e is directed the same as the
original curve inserted into the map.
overlap is true iff the added halfedges overlap halfedges already in the
map.

pmwx_cn.split_edge ( |
Planar_map::Halfedge_handle orig_edge,
Planar_map::Halfedge_handle new_edge,
Traits::X_curve c1,
Traits::X_curve c2) |
|
| |
called each time a pair of twin halfedges is split into two
pairs. The split operation creates a new pair of twin halfedges
(new_edge and its twin) and modifies the original
pair (orig_edge an its twin).
c1 and c2 are the curves after the split.

void
|
|
pmwx_cn.split_face ( |
Planar_map::Face_handle orig_face,
Planar_map::Face_handle new_face) |
|
| |
called each time a face of the planar map is being split by
the inserted curve into two faces: orig_face is the
original face and new_face is the new face.

|
void
|
|
pmwx_cn.add_hole ( |
Planar_map::Face_handle in_face,
Planar_map::Halfedge_handle new_hole) |
|
| |
called each time a hole is added to a face in_face.
new_hole is a halfedge on the new hole.
|
|
|
bool
|
pmwx_cn.have_support_curve ()
|
| |
returns true if edge_support_curve function can return the
supporting curve (used by the arrangement class).
|
|
|
Traits::X_curve
|
|
pmwx_cn.edge_support_curve ( |
Planar_map::Halfedge_handle edge) |
|
| |
returns the supporting curve of a edge, if it exists
(used by the arrangement class).
