Method Details

distance

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

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).
Parameters:
p1 - the other point

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)].
Parameters:
p1 - the other point

distanceSquared

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