## CGAL::side_of_oriented_sphere

#include <CGAL/predicates_d.h>

template <class ForwardIterator>
Oriented_side |
side_of_oriented_sphere ( | ForwardIterator first, ForwardIterator last, Point_d<R> p)
|  | returns the relative position of point p to the oriented sphere defined by the points in A = tuple [first,last) The order of the points in A is important, since it determines the orientation of the implicitly constructed sphere. If the points in A are positively oriented, the positive side is the bounded interior of the sphere. Precondition: A contains d+1 points in d-space. Requirement: The value type of ForwardIterator is Point_d<R>.
