CGAL 5.3  2D and 3D Linear Geometry Kernel

AdaptableFunctor
(with three arguments)Operations  
bool  operator() (const Kernel::Plane_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r) 
returns true, iff the signed distance from point q to plane p is smaller than the signed distance from point r to p .  
bool  operator() (const Kernel::Point_3 &p1, const Kernel::Point_3 &p2, const Kernel::Point_3 &p3, const Kernel::Point_3 &q, const Kernel::Point_3 &r) 
returns true, iff the signed distance from point q to the plane p defined by p1, p2, p3 is smaller than the signed distance from point r to p . More...  
bool Kernel::LessSignedDistanceToPlane_3::operator()  (  const Kernel::Point_3 &  p1, 
const Kernel::Point_3 &  p2,  
const Kernel::Point_3 &  p3,  
const Kernel::Point_3 &  q,  
const Kernel::Point_3 &  r  
) 
returns true, iff the signed distance from point q
to the plane p
defined by p1, p2, p3
is smaller than the signed distance from point r
to p
.
p, q
, and r
are not collinear.
