CGAL 4.7 - 2D and 3D Linear Geometry Kernel

Definition

Refines:: AdaptableFunctor (with three arguments)

See Also: CGAL::left_turn()

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.
