CGAL 5.6.1 - 2D and 3D Linear Geometry Kernel



A model of this concept must provide:

Kernel::Point_2 operator() (const CGAL::Origin &CGAL::ORIGIN)
 introduces a variable with Cartesian coordinates \( (0,0)\).
Kernel::Point_2 operator() (const Kernel::Point_2 &p)
 returns p. More...
Kernel::Point_2 operator() (const Kernel::Weighted_point_2 &wp)
 extracts the bare point from the weighted point.

◆ operator()()

Kernel::Point_2 Kernel::ConstructPoint_2::operator() ( const Kernel::Point_2 p)

returns p.

It is advised to return a const reference to p to avoid useless copies.
This peculiar requirement is necessary because some CGAL structures such as triangulations internally manipulate points whose type might be Point_2 or Weighted_point_2.
