## Functions

template<typename Kernel >
Comparison_result CGAL::compare_signed_distance_to_plane (const CGAL::Plane_3< Kernel > &h, const CGAL::Point_3< Kernel > &p, const CGAL::Point_3< Kernel > &q)
returns CGAL::LARGER iff the signed distance of p and h is larger than the signed distance of q and h, CGAL::SMALLER, iff it is smaller, and CGAL::EQUAL iff both are equal.

template<typename Kernel >
Comparison_result CGAL::compare_signed_distance_to_plane (const CGAL::Point_3< Kernel > &p, const CGAL::Point_3< Kernel > &q, const CGAL::Point_3< Kernel > &r, const CGAL::Point_3< Kernel > &s, const CGAL::Point_3< Kernel > &t)
returns CGAL::LARGER iff the signed distance of s and h is larger than the signed distance of t and h, CGAL::SMALLER, iff it is smaller, and CGAL::EQUAL iff both are equal, where h is the oriented plane through p, q and r.
