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 , and whose target is the intersection
of c and c2 of index , 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 non-zero 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. |
