Method Detail

leftRightTurn

public int leftRightTurn(Point2D p1,
                         Point2D q,
                         Point2D p2)

Specified by:

leftRightTurn in interface ThreeArgsGeomTests2D

Following copied from interface: jdsl.geomobj.api.ThreeArgsGeomTests2D

Parameters:

p1 - a point

q - a point

p2 - a point

Returns:

whether (p1,q,p2) form a GeomTester2D.LEFT_TURN, are GeomTester2D.COLLINEAR, or form a GeomTester2D.RIGHT_TURN

Throws:

InvalidPointException - if either p1, or q, or p2 is Point2D.INFINITE

compareDistances

public int compareDistances(Point2D q,
                            Point2D p1,
                            Point2D p2)

Specified by:

compareDistances in interface ThreeArgsGeomTests2D

Following copied from interface: jdsl.geomobj.api.ThreeArgsGeomTests2D

Parameters:

q - a point

p1 - a point

p2 - a point

Returns:

whether the distance between q and p1 is GeomTester2D.LESSER than, GeomTester2D.EQUAL to, or GeomTester2D.GREATER than the distance between q and p2

Throws:

InvalidPointException - if q is Point2D.INFINITE
