## CGAL::Regular_triangulation_euclidean_traits_3<R,Weight>

### Definition

The class Regular_triangulation_euclidean_traits_3<R,Weight> is designed as a default traits class for the class Regular_triangulation_3<RegularTriangulationTraits_3,TriangulationDataStructure_3>. It provides Weighted_point_3, a class for weighted points, which derives from the three dimensional point class R::Point_3.

The first argument R must be a model of the Kernel concept.

The second argument Weight of the class Regular_triangulation_euclidean_traits_3<R,Weight> is in fact optional: if is it not provided, R::RT will be used.

Note that this template class is specialized for CGAL::Exact_predicates_inexact_constructions_kernel, so that it is as if Regular_triangulation_filtered_traits_3 was used, i.e. you get filtered predicates automatically.

#include <CGAL/Regular_triangulation_euclidean_traits_3.h>

### Is Model for the Concept

RegularTriangulationTraits_3

### Inherits From

R

### Types

typedef R::Point_3 | Bare_point; | The type for point p of a weighted point p(w)=(p,wp).
typedef Weighted_point <Bare_point, Weight>
| Weighted_point_3;
