Bounded_side  operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r, const Kernel::Point_3 &s) 
returns the bounded side of the circle defined by p , q , and r on which s lies. More...  
Bounded_side Kernel::CoplanarSideOfBoundedCircle_3::operator()  (  const Kernel::Point_3 &  p, 
const Kernel::Point_3 &  q,  
const Kernel::Point_3 &  r,  
const Kernel::Point_3 &  s  
) 
returns the bounded side of the circle defined by p
, q
, and r
on which s
lies.
p
, q
, r
, and s
are coplanar and p
, q
, and r
are not collinear.
