CGAL 5.6 - 3D Spherical Geometry Kernel
AlgebraicKernelForSpheres::CompareXY Concept Reference

Definition

Operations

A model of this concept must provide:

CGAL::Comparison_result operator() (const AlgebraicKernelForSpheres::Root_for_spheres_2_3 &r1, const AlgebraicKernelForSpheres::Root_for_spheres_2_3 &r2)
 Compares the x and y (the two first) variables of two Root_for_spheres_2_3 lexicographically.
