Method Detail

closer

public Point2D closer(Point2D q1,
                      Point2D q2,
                      Point2D p)

Parameters:

q1 - a point

q2 - a point

p - a point

Returns:

the closer point to p between q1 and q2 (either q1 or q2 if they are equidistant from p)

Throws:

InvalidPointException - if either q1 or q2 or p is Point2D.INFINITE

farther

public Point2D farther(Point2D q1,
                       Point2D q2,
                       Point2D p)

Parameters:

q1 - a point

q2 - a point

p - a point

Returns:

the farther point to p between q1 and q2 (either q1 or q2 if they are equidistant from p)

Throws:

InvalidPointException - if either q1 or q2 or p is Point2D.INFINITE
