Point2d
public Point2d()
Constructs and initializes a Point2d to (0,0).
Point2d
public Point2d(double x,
double y) Constructs and initializes a Point2d from the specified xy coordinates.
x - the x coordinatey - the y coordinate
Point2d
public Point2d(Point2d p1)
Constructs and initializes a Point2d from the specified Point2d.
p1 - the Point2d containing the initialization x y data
Point2d
public Point2d(Point2f p1)
Constructs and initializes a Point2d from the specified Point2f.
p1 - the Point2f containing the initialization x y data
Point2d
public Point2d(Tuple2d t1)
Constructs and initializes a Point2d from the specified Tuple2d.
t1 - the Tuple2d containing the initialization x y data
Point2d
public Point2d(Tuple2f t1)
Constructs and initializes a Point2d from the specified Tuple2f.
t1 - the Tuple2f containing the initialization x y data
Point2d
public Point2d(p[] )
Constructs and initializes a Point2d from the specified array.
distance
public final double distance(Point2d p1)
Computes the distance between this point and point p1.
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).
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)].
distanceSquared
public final double distanceSquared(Point2d p1)
Computes the square of the distance between this point and point p1.
