Border Parameterization Methods

`#include <CGAL/Circular_border_parameterizer_3.h>`

Inherited by CGAL::Circular_border_arc_length_parameterizer_3< ParameterizationMesh_3 >, and CGAL::Circular_border_uniform_parameterizer_3< ParameterizationMesh_3 >.

## Definition

This is the base class of strategies that parameterize the border of a 3D surface onto a circle.

`Circular_border_parameterizer_3` is a pure virtual class, thus cannot be instantiated. It implements most of the algorithm. Subclasses just have to implement `compute_edge_length()` to compute a segment's length.

Implementation note: To simplify the implementation, `BorderParameterizer_3` models know only the `ParameterizationMesh_3` class. They do not know the parameterization algorithm requirements or the kind of sparse linear system used.

Is Model Of:
  `BorderParameterizer_3`
