Method Summary

Modifier and Type	Method	Description
static boolean	encroachesEdge(Point_2 p, Point_2[] e)	Tests whether point p lies in the diametral circle of edge e
private static Point_2[]	intersectSegmentWithCircle(Point_2 a, Point_2 b, Point_2 center, double radius)	This function is used by midpointOnUnitCircle(); it returns the intersection points between segment [a,b] and circle (center, radius), if they exist
static Point_2	midpointOnUnitCircle(Point_2[] e)	Computes the points of the bisector of edge e that lie on the unit circle, and returns the one closest to e
