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.
#include <CGAL/Circular_border_parameterizer_3.h>
Model of the BorderParameterizer_3 concept (although you cannot instantiate this class).
BorderParameterizer_3 models are Strategies [GHJV95]: they implement a strategy of border parameterization for models of ParameterizationMesh_3.
The full template declaration is:
template<class ParameterizationMesh_3>
class Circular_border_parameterizer_3;
