Constructors

o 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
o 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
o Point2d 
 public Point2d(javax.vecmath.Point2d p1)
Constructs and initializes a Point2d from the specified Point2d.

Parameters:
p1 - the Point2d containing the initialization x y data
o Point2d 
 public Point2d(javax.vecmath.Point2f p1)
Constructs and initializes a Point2d from the specified Point2f.

Parameters:
p1 - the Point2f containing the initialization x y data
o Point2d 
 public Point2d(javax.vecmath.Tuple2d t1)
Constructs and initializes a Point2d from the specified Tuple2d.

Parameters:
t1 - the Tuple2d containing the initialization x y data
o Point2d 
 public Point2d(javax.vecmath.Tuple2f t1)
Constructs and initializes a Point2d from the specified Tuple2f.

Parameters:
t1 - the Tuple2f containing the initialization x y data

Methods

o distanceSquared 
 public final double distanceSquared(javax.vecmath.Point2d p1)
Computes the square of the distance between this point and point p1.

Parameters:
p1 - the other point
o distance 
 public final double distance(javax.vecmath.Point2d p1)
Computes the distance between this point and point p1.

Parameters:
p1 - the other point
o distanceL1 
 public final double distanceL1(javax.vecmath.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
o distanceLinf 
 public final double distanceLinf(javax.vecmath.Point2d p1)
