Kernel::Sphere_3 Kernel::ConstructSphere_3::operator() ( const Kernel::Point_3 center,
const Kernel::FT squared_radius,
const Orientation orientation = COUNTERCLOCKWISE 
)

introduces a sphere initialized to the sphere with center center, squared radius squared_radius and orientation orientation.

Precondition
orientation \( \neq\) CGAL::COPLANAR, and furthermore, squared_radius \( \geq\) 0.

◆ operator()() [2/5]

Kernel::Sphere_3 Kernel::ConstructSphere_3::operator() ( const Kernel::Point_3 p,
const Kernel::Point_3 q,
const Kernel::Point_3 r,
const Kernel::Point_3 s 
)

introduces a sphere initialized to the unique sphere which passes through the points p, q, r and s.

The orientation of the sphere is the orientation of the point quadruple p, q, r, s.

Precondition
p, q, r, and s are not coplanar.
