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_y ( Point_2<Kernel> p, Point_2<Kernel> q) | |
| compares Cartesian y-coordinates of p and q. | ||
| Comparison_result | compare_y ( Point_3<Kernel> p, Point_3<Kernel> q) | |
| compares Cartesian y-coordinates of p and q. | ||
| Comparison_result | compare_y ( Point_2<Kernel> p, Line_2<Kernel> l1, Line_2<Kernel> l2) | |
| compares the y-coordinates of p and the intersection of lines l1 and l2, see (a) in the figure above. | ||
| Comparison_result | compare_y ( Line_2<Kernel> l, Line_2<Kernel> h1, Line_2<Kernel> h2) | |
| compares the y-coordinates of the intersection of line l with line h1 and with line h2, see (b) in the figure above. | ||
| Comparison_result | compare_y ( Line_2<Kernel> l1, Line_2<Kernel> l2, Line_2<Kernel> h1, Line_2<Kernel> h2) | |
| compares the y-coordinates of the intersection of lines l1 and l2 and the intersection of lines h1 and h2 , see (c) in the figure above. | ||
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_y ( Circular_arc_point_2<CircularKernel> p, Circular_arc_point_2<CircularKernel> q) | |
| compares the y-coordinates of p and q. | ||
| Comparison_result | compare_y ( Circular_arc_point_2<CircularKernel> p, Point_2<CircularKernel> q) | |
| compares the y-coordinates of p and q. | ||
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_y ( Circular_arc_point_3<SphericalKernel> p, Circular_arc_point_3<SphericalKernel> q) | |
| compares the y-coordinates of p and q. | ||
| Comparison_result | compare_y ( Circular_arc_point_3<SphericalKernel> p, Point_3<SphericalKernel> q) | |
| compares the y-coordinates of p and q. | ||
