CGAL::Homogeneous_converter< K1, K2, RTConverter, FTConverter > Class Template Reference

#include <CGAL/Homogeneous_converter.h>

Definition

template<typename K1, typename K2, typename RTConverter, typename FTConverter>
class CGAL::Homogeneous_converter< K1, K2, RTConverter, FTConverter >

Homogeneous_converter converts objects from the kernel traits K1 to the kernel traits K2. Those traits must be of the form Homogeneous<RT1> and Homogeneous<RT2> (or the equivalent with Simple_homogeneous). It then provides the following operators to convert objects from K1 to K2.

The third template parameter RTConverter is a function object that must provide K2::RT operator()(const K1::RT &n); that converts n to an K2::RT that has the same value.

The default value of this parameter is CGAL::NT_converter<K1::RT, K2::RT>, which uses the conversion operator from K1::RT to K2::RT.

Similarly, the fourth template parameter must provide K2::FT operator()(const K1::FT &n); that converts n to an K2::FT that has the same value. Its default value is CGAL::NT_converter<K1::FT, K2::FT>.
