Depending on which Cgal kernel is used, different versions of this global function are available. This is described below.
With the basic 2D and 3D Kernel (see Chapter 11)
Comparison_result | compare_xy ( Point_2<Kernel> p, Point_2<Kernel> q) | |
Compares the Cartesian coordinates of points p and q lexicographically in xy order: first x-coordinates are compared, if they are equal, y-coordinates are compared. | ||
Comparison_result | compare_xy ( Point_3<Kernel> p, Point_3<Kernel> q) | |
Compares the Cartesian coordinates of points p and q lexicographically in xy order: first x-coordinates are compared, if they are equal, y-coordinates are compared. |
With the 2D Circular Kernel (see Chapter 13)
#include <CGAL/global_functions_circular_kernel_2.h>
If this kernel is used, in addition to the function and the combination of 2D types described above, another version of the function is provided.
Comparison_result | compare_xy ( Circular_arc_point_2<CircularKernel> p, Circular_arc_point_2<CircularKernel> q) | |
Compares the x and y Cartesian coordinates of points p and q lexicographically. | ||
Comparison_result | compare_xy ( Circular_arc_point_2<CircularKernel> p, Point_2<CircularKernel> q) | |
Compares the x and y Cartesian coordinates of points p and q lexicographically. |
With the 3D Spherical Kernel (see Chapter 14)
#include <CGAL/global_functions_spherical_kernel_3.h>
If this kernel is used, in addition to the function and the combination of 2D types described above, another version of the function is provided.
Comparison_result | compare_xy ( Circular_arc_point_3<SphericalKernel> p, Circular_arc_point_3<SphericalKernel> q) | |
Compares the x and y Cartesian coordinates of points p and q lexicographically. | ||
Comparison_result | compare_xy ( Circular_arc_point_3<SphericalKernel> p, Point_3<SphericalKernel> q) | |
Compares the x and y Cartesian coordinates of points p and q lexicographically. |
