## Modules
| CGAL::natural_neighbor_coordinates_2()
| The functions `natural_neighbor_coordinates_2()` compute natural neighbor coordinates, also called Sibson's coordinates, for `2D` points provided a two-dimensional triangulation and a query point in the convex hull of the vertices of the triangulation.
| CGAL::regular_neighbor_coordinates_2()
| The functions `regular_neighbor_coordinates_2()` compute natural neighbor coordinates, also called Sibson's coordinates, for weighted `2D` points provided a two-dimensional regular triangulation and a (weighted) query point inside the convex hull of the vertices of the triangulation.
