CircularKernel::Circular_arc_2 CircularKernel::ConstructCircularArc_2::operator() | ( | const CircularKernel::Circle_2 & | c | ) |
Constructs an arc from a full circle.

Constructs the unique circular arc whose supporting circle is c
, and whose source is the intersection of c
and c1
with index b1
, and whose target is the intersection of c
and c2
of index b2
, where intersections are ordered lexicographically, and when traversing the circle in counterclockwise direction.
c
intersects both c1
and c2
, and the arc defined by the intersections has non-zero length. CircularKernel::Circular_arc_2 CircularKernel::ConstructCircularArc_2::operator() | ( | const CircularKernel::Circle_2 & | c, |
const CircularKernel::Circular_arc_point_2 & | p1, | ||
const CircularKernel::Circular_arc_point_2 & | p2 | ||
) |
Construct the circular arc supported by c
, whose source is p1
and whose target is p2
when traversing the circle in counterclockwise direction.
p1
and p2
lie on c
. CircularKernel::Circular_arc_2 CircularKernel::ConstructCircularArc_2::operator() | ( | const CircularKernel::Circle_2 & | c, |

Same, for intersections defined by lines instead of circles.
CircularKernel::Circular_arc_2 CircularKernel::ConstructCircularArc_2::operator() | ( | const CircularKernel::Point_2 & | p, |
const CircularKernel::Point_2 & | q, | ||
const 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.
p
, q
, and r
are not collinear.
