PMPHolefillingVisitor Concept Reference

Definition

The concept PMPHolefillingVisitor defines the requirements for the visitor used in hole-filling-related functions . The hole filling may use a 2D constrained triangulation for almost planar holes (planar phase). If that is not appropriate or fails it may use an algorithm with a quadratic running time relying on the 3D Delaunay triangulation (quadratic phase). If that fails, it uses an algorithm with cubic running time (cubic phase).

Member Function Documentation

◆ end_planar_phase()

void PMPHolefillingVisitor::end_planar_phase ( bool  success) const

called when the planar hole filling algorithm stops.

Parameters
successtrue when the hole could be filled in this phase.

◆ end_quadratic_phase()

void PMPHolefillingVisitor::end_quadratic_phase ( bool  success) const

called when the algorithm with quadratic running time ends.

Parameters
successtrue when the hole could be filled in this phase.

◆ quadratic_step()

void PMPHolefillingVisitor::quadratic_step ( ) const

called at each step.

There may be less than n calls as this is an upperbound.

◆ start_cubic_phase()

void PMPHolefillingVisitor::start_cubic_phase ( std::size_t  n) const

called when the algorithm with cubic running time starts.

Parameters
nthe upperbound on the number of steps

◆ start_quadratic_phase()

void PMPHolefillingVisitor::start_quadratic_phase ( std::size_t  n) const

called when the algorithm with quadratic running time starts.

Parameters
nthe upperbound on the number of steps
