Constructor Detail

Point2d

public Point2d(double x,
       double y)

Constructs and initializes a Point2d from the specified xy coordinates.

Parameters:

x - the x coordinate

y - the y coordinate

Point2d

public Point2d(double[] p)

Constructs and initializes a Point2d from the specified array.

Parameters:

p - the array of length 2 containing xy in order

Point2d

public Point2d(Point2d p1)

Constructs and initializes a Point2d from the specified Point2d.

Parameters:

p1 - the Point2d containing the initialization x y data

Method Detail

distanceSquared

public final double distanceSquared(Point2d p1)

Computes the square of the distance between this point and point p1.

Parameters:

p1 - the other point

distance

public final double distance(Point2d p1)

Computes the distance between this point and point p1.

Parameters:

p1 - the other point

distanceL1

public final double distanceL1(Point2d p1)

Computes the L-1 (Manhattan) distance between this point and point p1. The L-1 distance is equal to abs(x1-x2) + abs(y1-y2).

Parameters:

p1 - the other point

distanceLinf

public final double distanceLinf(Point2d p1)

Computes the L-infinite distance between this point and point p1. The L-infinite distance is equal to MAX[abs(x1-x2), abs(y1-y2)].

Parameters:

p1 - the other point
