Oriented_side
|
|
gt.side_of_oriented_circle ( |
Point p0,
Point p1,
Point p2,
Point test) |
|
| |
Gives the Oriented_side of point test with respect to
the oriented circumscribing circle of points p0, p1 and p2.
This answers the in_circle test if the Orientation
of Points p0, p1 and p2 is known,
which is the case for the points associated with the three
vertices of a triangulation face.

Point
|
gt.circumcenter ( Point p, Point q, Point r)
|
| |
Returns the center point equidistant from p, q and
r. This method is required only if the duality functions are called.
|
|
|
Line
|
gt.bisector ( Segment s)
|
| |
Returns the bisector line of segment s. This method is required only if duality functions
are called.
