\begin{ccRefFunction}{compare_xyz}

Depending on which \cgal\ \ccHtmlNoLinksFrom{kernel} is used,
|
|
different versions of this global function are available. This is
|
|
described below.
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
\paragraph{With the basic 3D Kernel} (see Chapter~\ref{chapter-kernel-23})
|
|
|
|
\ccFunction{Comparison_result
|
|
compare_xyz(const Point_3<Kernel>& p, const Point_3<Kernel>& q);}
|
|
{Compares the Cartesian coordinates of points \ccStyle{p} and
|
|
\ccStyle{q} lexicographically in $xyz$ order: first
|
|
$x$-coordinates are compared, if they are equal, $y$-coordinates
|
|
are compared, and if both $x$- and $y$- coordinate are equal,
|
|
$z$-coordinates are compared.}
|
|
|
|
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
|
|
\paragraph{With the 3D Spherical Kernel} (see Chapter~\ref{chapter-spherical-kernel})
|
|
|
|
\ccInclude{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.
|
|
|
|
\ccFunction{Comparison_result
|
|
compare_xyz(const Circular_arc_point_3<SphericalKernel> &p,
|
|
const Circular_arc_point_3<SphericalKernel> &q);}
|
|
{Compares the Cartesian coordinates of points \ccStyle{p} and
|
|
\ccStyle{q} lexicographically.}
|
|
|
|
\ccFunction{Comparison_result
|
|
compare_xyz(const Circular_arc_point_3<SphericalKernel> &p,
|
|
const Point_3<SphericalKernel> &q);}
|
|
{Compares the Cartesian coordinates of points \ccStyle{p} and
|
|
\ccStyle{q} lexicographically.}
