## 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

  success | `true` 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

  success | `true` 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

  n | the 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

  n | the upperbound on the number of steps
