Description copied from interface: PointI

Returns the Y coordinate.

Specified by:

y in interface PointI

z

public double z()

Description copied from interface: PointI

Returns the z coordinate.

Specified by:

z in interface PointI

getCoordinate

public double getCoordinate(int i)

Description copied from interface: PointI

Returns individual coordinates by ordinality.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

getDirectionTo

public double getDirectionTo(PointI point)

Description copied from interface: PointI

Returns the direction to the argument. The return value is in the range -PI to +PI.

directionTo

public double directionTo(PointI point)

Returns the direction to the argument. The return value is in the range -PI to +PI and is measured in the xy-plane and in the direction of the positive x-axis. If angle is positive if 'point' is counterclockwise and negative if it is clockwise.

Specified by:

directionTo in interface PointI

distanceProxyTo

public double distanceProxyTo(PointI point)

Returns an easily computable proxy that can be used to compare the distance between two points.

Returns:

the square of the distance.

distanceTo
