Method Detail

closer

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

Specified by:

closer in interface GeomSelector2D

Following copied from interface: jdsl.geomobj.api.GeomSelector2D

                       Point2D q2,
                       Point2D p)

Specified by:

farther in interface GeomSelector2D

Following copied from interface: jdsl.geomobj.api.GeomSelector2D

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)
