Member Function Documentation

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.
