Kernel::Sphere_3
|
|
| |
introduces a sphere initialized to the sphere with center center,
squared radius squared_radius and orientation
orientation.
|
|
|
Kernel::Sphere_3
|
fo.operator() ( Kernel::Point_3 p, Kernel::Point_3 q, Kernel::Point_3 r, 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. |
|
|
|
Kernel::Sphere_3
|
|
| |
introduces a sphere initialized to the smallest sphere which passes
through the points p, q, and r. The orientation of
the sphere is o.
|
|
|
Kernel::Sphere_3
|
fo.operator() ( Kernel::Point_3 p, Kernel::Point_3 q, Orientation o = COUNTERCLOCKWISE)
|
| |
introduces a sphere initialized to the smallest sphere which passes
through the points p and q. The orientation of
the sphere is o.
|
|
|
Kernel::Sphere_3
|
fo.operator() ( Kernel::Point_3 center, Orientation orientation = COUNTERCLOCKWISE)
|
| |
introduces a sphere s initialized to the sphere with center
center, squared radius zero and orientation orientation.
| Postcondition: | s.is_degenerate() = true. |
|
|
|
Kernel::Sphere_3
|
fo.operator() ( Kernel::Circle_3 c)
|
| |
introduces a sphere initialized to the diametral sphere of
the circle.
