## Kernel::HasOnPositiveSide_3

A model for this must provide:

bool

fo.operator() ( | Kernel::Plane_3 h, Kernel::Point_3 p)

|  | returns true iff p lies on the positive side of h (h is considered a halfspace).

bool

fo.operator() ( | Kernel::Sphere_3 s, Kernel::Point_3 p)

|  | returns true iff p lies on the positive side of s.

bool

fo.operator() ( | Kernel::Tetrahedron_3 t, Kernel::Point_3 p)

|  | returns true iff p lies on the positive side of t.
