CGAL 5.1.1  dD Geometry Kernel

#include <CGAL/Cartesian_d.h>
A model for Kernel_d
(and even KernelWithLifting_d
) that uses Cartesian coordinates to represent the geometric objects.
In order for Cartesian_d
to model Euclidean geometry in \( E^d\) , for some mathematical field \( E\) (e.g., the rationals \(\mathbb{Q}\) or the reals \(\mathbb{R}\)), the template parameter FieldNumberType
must model the mathematical field \( E\). That is, the field operations on this number type must compute the mathematically correct results. If the number type provided as a model for FieldNumberType
is only an approximation of a field (such as the builtin type double
), then the geometry provided by the kernel is only an approximation of Euclidean geometry.
