Depending on which Cgal kernel is used, different versions of this global function are available. This is described below.
With the basic 3D Kernel (see Chapter 11)
| Comparison_result | compare_z ( Point_3<Kernel> p, Point_3<Kernel> q) | |
| compares the z-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_z ( Circular_arc_point_3<SphericalKernel> p, Circular_arc_point_3<SphericalKernel> q) | |
| compares the z-coordinates of p and q. | ||
| Comparison_result | compare_z ( Circular_arc_point_3<SphericalKernel> p, Point_3<SphericalKernel> q) | |
| compares the z-coordinates of p and q. | ||
