## CGAL::Extended_homogeneous<RT>

### Definition

The class Extended_homogeneous<RT> serves as a traits class for the class CGAL::Nef_polyhedron_2<T>. It uses a polynomial component representation based on a Euclidean ring number type RT.

#include <CGAL/Extended_homogeneous.h>

### Is Model for the Concept

ExtendedKernelTraits_2

### Creation

Extended_homogeneous<RT> traits;
| default constructor.

### Requirements

To make an Euclidean ring number type RT_model work with this class the number type must support a gcd computation in namespace CGAL::NTS. CGAL provides a function template for this, which will be used by default when your number type is not one of the built-in number types, one of the number types distrubuted with CGAL or one of the LEDA number types.

### Operations

Fits all operation requirements of the concept.
