public class Point2f
extends Tuple2f
A 2 element point that is represented by single precision floating point x,y coordinates.

Constructor Index

o Point2f()
Constructs and initializes a Point2f to (0,0).
o Point2f(float, float)
Constructs and initializes a Point2f from the specified xy coordinates.
o Point2f(float[])
Constructs and initializes a Point2f from the specified array.
o Point2f(Point2f)
Constructs and initializes a Point2f from the specified Point2f.

Method Index

o distance(Point2f)
Computes the distance between this point and point p1.
o distanceL1(Point2f)
Computes the L-1 (Manhattan) distance between this point and point p1.
o distanceLinf(Point2f)
Computes the L-infinite distance between this point and point p1.
o distanceSquared(Point2f)
Computes the square of the distance between this point and point p1.

Constructors

o Point2f 
 public Point2f(float x,
                float y)
Constructs and initializes a Point2f from the specified xy coordinates.

Parameters:
x - the x coordinate
y - the y coordinate
o Point2f 
 public Point2f(float p[])
Constructs and initializes a Point2f from the specified array.

Parameters:
p - the array of length 2 containing xy in order
o Point2f 
 public Point2f(Point2f p1)
Constructs and initializes a Point2f from the specified Point2f.

Parameters:
p1 - the Point2f containing the initialization x y data
o Point2f 
 public Point2f()
Constructs and initializes a Point2f to (0,0).

Methods

o distanceSquared 
 public final float distanceSquared(Point2f p1)
Computes the square of the distance between this point and point p1.

Parameters:
p1 - the other point
o distance 
 public final float distance(Point2f p1)
Computes the distance between this point and point p1.

Parameters:
p1 - the other point
o distanceL1 
 public final float distanceL1(Point2f 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).

o distanceLinf 
 public final float distanceLinf(Point2f 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)].
