Operations  
X_monotone_curve_2  operator() (const Point_2 &p, const Point_2 &q) 
Construct the minor geodesic arc from two endpoints. More...  
X_monotone_curve_2  operator() (const Direction_3 &normal) 
Construct a full great circle from a normal to a plane. More...  
X_monotone_curve_2  operator() (const Point_2 &p, const Point_2 &q, const Direction_3 &normal) 
Construct a geodesic arc from two endpoints and a normal to the plane containing the arc. More...  
X_monotone_curve_2 CGAL::Arr_geodesic_arc_on_sphere_traits_2< Kernel, X, Y >::Construct_x_monotone_curve_2::operator()  (  const Point_2 &  p, 
const Point_2 &  q  
) 
Construct the minor geodesic arc from two endpoints.
The minor arc is the one with the smaller angle among the two geodesic arcs with the given endpoints.
An arc is vertical, iff
[in]  p  the first endpoint. 
[in]  q  the second endpoint. 
X_monotone_curve_2 CGAL::Arr_geodesic_arc_on_sphere_traits_2< Kernel, X, Y >::Construct_x_monotone_curve_2::operator()  (  const Direction_3 &  normal  ) 
Construct a full great circle from a normal to a plane.
Observe that the constrcted arc has one endpoint that lies on the identification curve. This point is considered both the source and target (and also the left and right) point of the arc.
normal  the normal to the plane containing the great circle. 
X_monotone_curve_2 CGAL::Arr_geodesic_arc_on_sphere_traits_2< Kernel, X, Y >::Construct_x_monotone_curve_2::operator()  (  const Point_2 &  p, 
const Point_2 &  q,  
const Direction_3 &  normal  
) 
Construct a geodesic arc from two endpoints and a normal to the plane containing the arc.
The two endpoints determine the plane. The normal determines the orientation of the plane and the final arc (whether its the minor arc or the major arc). The righthand rule can be used to select the appropriate normal.
[in]  p  the first endpoint. 
[in]  q  the second endpoint. 
[in]  normal  the normal to the oriented plane containing the arc.
