Functions used by corefine() when edges are split or created | |

called before the edge of h in tm is split. More... | |

Functions used by Boolean operations functions using corefinement. | |
These functions are not needed if you only call | |
void | before_face_copy (face_descriptor f_src, const Triangle_mesh &tm_src, Triangle_mesh &tm_tgt) |
called before importing the face f_src of tm_src in tm_tgt | |
void | after_face_copy (face_descriptor f_src, const Triangle_mesh &tm_src, face_descriptor f_tgt, Triangle_mesh &tm_tgt) |

void | before_edge_copy (halfedge_descriptor h_src/, const TriangleMesh &tm_src, TriangleMesh &tm_tgt) |
called before importing the edge of h_src of tm_src in tm_tgt . There is one call per edge. | |
void | after_edge_copy (halfedge_descriptor h_src, const TriangleMesh &tm_src, halfedge_descriptor h_tgt, TriangleMesh &tm_tgt) |
called after importing the edge of h_src of tm_src in tm_tgt . More... | |
void | before_edge_duplicated (halfedge_descriptor h, TriangleMesh &tm) |
called before a patch boundary edge is duplicated to disconnect patches of tm (When an in-place operation and an out-of-place are both requested). More... | |
void | after_edge_duplicated (halfedge_descriptor h_src, halfedge_descriptor h_new, TriangleMesh &tm) |
called when the edge of h_src has been duplicated into h_new in tm (When an in-place operation and an out-of-place are both requested). More... | |
void | intersection_edge_copy (halfedge_descriptor h_src1, const TriangleMesh &tm_src1, halfedge_descriptor h_src2, const TriangleMesh &tm_src2, halfedge_descriptor h_tgt, TriangleMesh &tm_tgt) |
called when an intersection edge (represented in input meshes tm_src1 and tm_src2 by h_src1 and h_src2 , respectively) is imported in tm_tgt as h_tgt . More... | |
void PMPCorefinementVisitor::add_retriangulation_edge | ( | halfedge_descriptor | h, |
TriangleMesh & | tm | ||
) |
called when a new edge has been added to triangulate a face.
The face triangulated is f_split
in the last call to before_subface_creations(f_split, tm)
. There is only one call per edge.
void PMPCorefinementVisitor::after_edge_copy | ( | halfedge_descriptor | h_src, |
const TriangleMesh & | tm_src, | ||
halfedge_descriptor | h_tgt, | ||
TriangleMesh & | tm_tgt | ||
) |
called after importing the edge of h_src
of tm_src
in tm_tgt
.
The corresponding new halfedge is h_tgt
. There is only one call per edge.
void PMPCorefinementVisitor::after_edge_duplicated | ( | halfedge_descriptor | h_src, |
halfedge_descriptor | h_new, | ||
TriangleMesh & | tm | ||
) |
called when the edge of h_src
has been duplicated into h_new
in tm
(When an in-place operation and an out-of-place are both requested).
void PMPCorefinementVisitor::after_face_copy | ( | face_descriptor | f_src, |
const Triangle_mesh & | tm_src, | ||
face_descriptor | f_tgt, | ||
Triangle_mesh & | tm_tgt | ||
) |
called after importing the face f_src
of tm_src
in tm_tgt
.
The new face is f_tgt
. Note that the call is placed just after a call to add_face()
so the halfedge pointer is not set yet.
void PMPCorefinementVisitor::after_subface_created | ( | face_descriptor | f_new, |
Triangle_mesh & | tm | ||
) |
called after creating a new triangle face f_new
in tm
to triangulate the face passed to before_subface_creations()
.
Note that the call is placed just after a call to add_face()
so the halfedge pointer is not set yet.
void PMPCorefinementVisitor::before_edge_duplicated | ( | halfedge_descriptor | h, |
TriangleMesh & | tm | ||
) |
called before a patch boundary edge is duplicated to disconnect patches of tm
(When an in-place operation and an out-of-place are both requested).
void PMPCorefinementVisitor::before_edge_split | ( | halfedge_descriptor | h, |
TriangleMesh & | tm | ||
) |
called before the edge of h
in tm
is split.
Each subsequent call to edge_split()
until the call to after_edge_split()
will correspond to the split of that edge. If edge_split(h_i, tm)
is called for i=1
to n
, h_1
, h_2
, ... ,h_n
, h
is the sequence of halfedges representing the edge split (with the same initial orientation). There is only one call per edge.
void PMPCorefinementVisitor::before_subface_creations | ( | face_descriptor | f_split, |
Triangle_mesh & | tm | ||
) |
called before the triangulation of f_split
in tm
.
Note that f_split
will be one of the faces of the triangulation. Each subsequent call to before_subface_created()
/after_subface_created()
will correspond to the creation of a new face of the triangulation of f_split
.
void PMPCorefinementVisitor::intersection_edge_copy | ( | halfedge_descriptor | h_src1, |
const TriangleMesh & | tm_src1, | ||
halfedge_descriptor | h_src2, | ||
const TriangleMesh & | tm_src2, | ||
halfedge_descriptor | h_tgt, | ||
TriangleMesh & | tm_tgt | ||
) |
called when an intersection edge (represented in input meshes tm_src1
and tm_src2
by h_src1
and h_src2
, respectively) is imported in tm_tgt
as h_tgt
.
There is only one call per edge. (Called only when an out-of-place operation is requested)
