Operations

A model of this concept must provide:

bool operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q, const Kernel::Point_2 &r)
 returns true iff the three points p, q and r form a left turn or if they are collinear and the distance of q to p is larger than the distance of r to p, where p is the point passed to the object at construction. More...

◆ operator()()

bool Kernel::LessRotateCCW_2::operator() ( const Kernel::Point_2 p,
const Kernel::Point_2 q,
const Kernel::Point_2 r 
)

returns true iff the three points p, q and r form a left turn or if they are collinear and the distance of q to p is larger than the distance of r to p, where p is the point passed to the object at construction.

Precondition
p does not lie in the interior of the segment rq, i.e. p is an extreme point with respect to \( \{p,q,r\}\).
