◆ are_ordered_along_line() [1/2]

template<typename Kernel >
bool CGAL::are_ordered_along_line ( const CGAL::Point_2< Kernel > &  p,
const CGAL::Point_2< Kernel > &  q,
const CGAL::Point_2< Kernel > &  r 
)

#include <CGAL/Kernel/global_functions.h>

returns true, iff the three points are collinear and q lies between p and r.

Note that true is returned, if q==p or q==r.

◆ are_ordered_along_line() [2/2]

template<typename Kernel >
bool CGAL::are_ordered_along_line ( const CGAL::Point_3< Kernel > &  p,
const CGAL::Point_3< Kernel > &  q,
const CGAL::Point_3< Kernel > &  r 
)

#include <CGAL/Kernel/global_functions.h>

returns true, iff the three points are collinear and q lies between p and r.

Note that true is returned, if q==p or q==r.
