CGAL 5.1 - 2D and 3D Linear Geometry Kernel

Definition

Operations

A model of this concept must provide:

Comparison_result operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &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.
