Method Details

intersectCircleCircleEx

public static IntersectionResultEx intersectCircleCircleEx(Point2D c1,
 double r1,
 Point2D c2,
 double r2)

Computes the intersection between circle 1 and circle 2.

Parameters:

intersectCircleCircleEx

public static IntersectionResultEx intersectCircleCircleEx(double c1x,
 double c1y,
 double r1,
 double c2x,
 double c2y,
 double r2,
 double epsilon)

Computes the intersection between the given circles 1 and 2.

Parameters:

c1x - the center of circle 1

c1y - the center of circle 1

r1 - the radius of circle 1

c2x - the center of circle 2

c2y - the center of circle 2

r2 - the radius of circle 2

intersectCircleCircle

public static IntersectionResult intersectCircleCircle(double c1x,
 double c1y,
 double r1,
 double c2x,
 double c2y,
 double r2,
 double epsilon)

Computes the intersection between the given circles 1 and 2.

This method can produce the following IntersectionStatus codes:

IntersectionStatus.INTERSECTION

The circles intersect at the IntersectionPoints given in the result.

IntersectionStatus.NO_INTERSECTION_INSIDE

Circle 1 is inside circle 2.

IntersectionStatus.NO_INTERSECTION_OUTSIDE

Circle 1 is outside circle 2.

IntersectionStatus.NO_INTERSECTION_COINCIDENT

Circle 1 is same as circle 2 up to the given epsilon.

Parameters:

c1x - the center of circle 1

c1y - the center of circle 1

r1 - the radius of circle 1

c2x - the center of circle 2

c2y - the center of circle 2

r2 - the radius of circle 2

Returns:

computed intersection with parameters of circle 1 at the intersection point
