Public Types
typedef unspecified_type	face_descriptor
	Face descriptor type.

Functions used by triangulate_face() and triangulate_faces()
void	before_subface_creations (face_descriptor f_split)
	called before the triangulation of f_split.
void	after_subface_creations ()
	called when the triangulation of a face in tm is finished.
void	after_subface_created (face_descriptor f_new)
	called after creating a new triangle face f_new to triangulate the face passed to before_subface_creations().
bool	accept_face (face_descriptor f, vertex_descriptor v0, vertex_descriptor v1, vertex_descriptor v2)
	called before considering a triangle made of vertices (v0,v1,v2) to triangulate f.

Member Function Documentation

accept_face()

bool PMPTriangulateFaceVisitor::accept_face	(	face_descriptor	f,
		vertex_descriptor	v0,
		vertex_descriptor	v1,
		vertex_descriptor	v2
	)

called before considering a triangle made of vertices (v0,v1,v2) to triangulate f.

If false is returned, the triangle will not be used. If true is returned, the triangle will be added to the candidate triangles.

after_subface_created()

void PMPTriangulateFaceVisitor::after_subface_created

(

face_descriptor

f_new

)

called after creating a new triangle face f_new 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.

before_subface_creations()

void PMPTriangulateFaceVisitor::before_subface_creations

(

face_descriptor

f_split

)

called before the triangulation of f_split.

Note that f_split will be one of the faces of the triangulation. Each subsequent call to after_subface_created() will correspond to the creation of a new face of the triangulation of f_split.
