template<class OutputIterator >

OutputIterator SphericalKernel::Intersect_3::operator()	(	const Type1 &	obj1,
		const Type2 &	obj2,
		OutputIterator	intersections
	)

Copies in the output iterator the intersection elements between the two objects.

intersections iterates on elements of type CGAL::Object, in lexicographic order when this ordering is defined on the computed objects.

Type1 and Type2 can both be either:

depending on the types Type1 and Type2, the computed CGAL::Object's can be assigned to

std::pair< SphericalKernel::Circular_arc_point_3, unsigned>, where the unsigned integer is the multiplicity of the corresponding intersection point between obj_1 and obj_2,
Type1, when Type1 and Type2 are equal, and if the two objects obj1 and obj2 are equal,
SphericalKernel::Line_3 or SphericalKernel::Circle_3 when Type1 and Type2 are two-dimensional objects intersecting along a curve (2 planes, or 2 spheres, or one plane and one sphere),
SphericalKernel::Circular_arc_3 in case of an overlap of two circular arcs or
SphericalKernel::Line_arc_3 in case of an overlap of two line segments.

template<class OutputIterator >

OutputIterator SphericalKernel::Intersect_3::operator()	(	const Type1 &	obj1,
		const Type2 &	obj2,
		const Type3 &	obj3,
		OutputIterator	intersections
	)

Copies in the output iterator the intersection elements between the three objects.

intersections iterates on elements of type CGAL::Object, in lexicographic order when this ordering is defined on the computed objects.

Type1, Type2 and Type3 can be either:

and depending of these types, the computed CGAL::Object's can be assigned to

std::pair< SphericalKernel::Circular_arc_point_3, unsigned>, where the unsigned integer is the multiplicity of the corresponding intersection point,
SphericalKernel::Circle_3 or
Type1, when Type1, Type2 and Type3 are equal, and if the three objects obj1 and obj2 and obj3 are equal.
