There are several overloaded function templates called Oriented_side() that compute the relative position of either (i) two polygons or (ii) a point and a polygon. This group of function templates is divided into two subgroups.

Oriented Side of two Polygons

Every function template in the first subgroup accepts two polygons pgn1 and pgn2. It returns ON_POSITIVE_SIDE if the two given polygons pgn1 and pgn2 intersect in their interiors, ON_NEGATIVE_SIDE if pgn1 and pgn2 do not intersect at all, and ON_ORIENTED_BOUNDARY if pgn1 and pgn2 intersect only in their boundaries.

A function template in this subgroup has one of the two following signatures:

1.1.	`Oriented_side oriented_side(const Type1& pgn1, const Type2& pgn2, UsePolylines = Tag_true());`
1.2.	`Oriented_side oriented_side(const Type1& pgn1, const Type2& pgn2);`
2.	`Oriented_side oriented_side(const Type1& pgn1, const Type2& pgn2, const GpsTraits& traits);`

Oriented Side of a Point and a Polygon

The functions in the second group accept a point p and a polygon pgn. Each function in this group returns ON_POSITIVE_SIDE if the point p is in the interior of pgn, ON_NEGATIVE_SIDE if p is in the exterior of pgn, and ON_ORIENTED_BOUNDARY if p is on the boundary of pgn.

A function in this subgroup has one of the following signatures:

3.1.	`Oriented_side oriented_side(const Point_2& p, const Type& pgn, UsePolylines = Tag_true());`
3.2.	`Oriented_side oriented_side(const Point_2& p, const Type& pgn);`
4.	`Oriented_side oriented_side(const Point_2& p, const Type& pgn, const GpsTraits& traits);`

Template Parameters

UsePolylines determines whether the boundaries of the input polygons are treated as cyclic sequences of single ( \(x\)-monotone) segments or as cyclic sequences of ( \(x\)-monotone) polylines. If substituted with CGAL::Tag_true, which is the default, the input polygons are converted to general polygons bounded by polylines before the operation is actually performed. If substituted with CGAL::Tag_false, the input polygons are used as is. Refer to Traits Selection for more information.

The types Type1 and Type2 of the parameters must be convertible to the types specified in a row in the following table, respectively.
The types that apply to signature (1.1.) above are restricted to those listed in rows 1–4 in the table below.
The types that apply to signature (1.2.) above are restricted to those listed in rows 5–8 in the table below.

	Type1	Type2
1	`Polygon_2`	`Polygon_2`
2	`Polygon_2`	`Polygon_with_holes_2`
3	`Polygon_with_holes_2`	`Polygon_2`
4	`Polygon_with_holes_2`	`Polygon_with_holes_2`
5	`General_polygon_2`	`General_polygon_2`
6	`General_polygon_2`	`General_polygon_with_holes_2`
7	`General_polygon_with_holes_2`	`General_polygon_2`
8	`General_polygon_with_holes_2`	`General_polygon_with_holes_2`

In (3.1.) Type must be convertible to either Polygon_2 or Polygon_with_holes_2.
In (3.2.) Type must be convertible to either General_polygon_2 or General_polygon_with_holes_2.
In (4.) Type must be convertible to any of the four types above.

Parameters

p	the input point.
pgn	the input polygon.
pgn1,pgn2	the input polygons.
traits	an optional traits object.
