CircularKernel::Circular_arc_2

fo (
CircularKernel::Circle_2 c
)

Constructs an arc from a full circle.


CircularKernel::Circular_arc_2


 
Construct the circular arc supported by c, whose source is
p1 and whose target is p2 when traversing the circle in
counterclockwise direction.
Precondition:  p1 and p2 lie on c. 


CircularKernel::Circular_arc_2


 
Constructs the unique circular arc whose supporting circle is
c, and whose source is the intersection of c
and c1 with index $$b_{1}, and whose target is the intersection
of c and c2 of index $$b_{2}, where intersections are
ordered lexicographically, and when traversing the circle in
counterclockwise direction.
Precondition:  c intersects both c1 and c2, and the arc
defined by the intersections has nonzero length. 


CircularKernel::Circular_arc_2


 
Same, for intersections defined by lines instead of circles.


CircularKernel::Circular_arc_2

fo (
CircularKernel::Point_2 p
,
CircularKernel::Point_2 q
,
CircularKernel::Point_2 r
)

 
Constructs an arc that is supported by the circle of type
CircularKernel::Circle_2 passing through the points p,
q and r. The source and target are respectively p
and r, when traversing the supporting circle in the
counterclockwise direction.
Note that, depending on the orientation of the point triple
(p,q,r), q may not lie on the arc.
Precondition:  p, q, and r are not collinear.
