Function Documentation

template<typename Kernel >
Comparison_result CGAL::compare_lexicographically ( const CGAL::Point_2< Kernel > &  p,
const CGAL::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.

This is the same function as compare_xy and exists for compatibility with Point_d<Kernel>.

template<typename Kernel >
Comparison_result CGAL::compare_lexicographically ( const CGAL::Point_3< Kernel > &  p,

Compares the Cartesian coordinates of points p and 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.

This is the same function as compare_xyz and exists for compatibility with Point_d<Kernel>.
