CGAL 6.0 - 2D and 3D Linear Geometry Kernel
|
#include <CGAL/Cartesian_converter.h>
Cartesian_converter converts objects from the kernel traits K1 to the kernel traits K2 using NTConverter to do the conversion.
Those traits must be of the form Cartesian<FT1> and Cartesian<FT2> (or the equivalent with Simple_cartesian). It then provides the following operators to convert objects from K1 to K2.
The third template parameter NTConverter is a function object that must provide K2::FT operator()(K1::FT n) that converts n to an K2::FT which has the same value.
The default value of this parameter is CGAL::NT_converter<K1::FT, K2::FT>.
Example
In the following example, we compute exactly the intersection point between a line and a triangle, and we then create a double approximation of this point.

Operations | |
Similar operators are defined for the other kernel traits types | |
| K2::Point_2 | operator() (const K1::Point_2 &p) |
returns a K2::Point_2 which coordinates are those of p, converted by NTConverter. | |
