Method Summary | |
---|---|
float | distance(Point4f p1)
Returns the distance between this point and point p1. |
float | distanceL1(Point4f p1)
Computes the L-1 (Manhattan) distance between this point and point p1.
|
float | distanceLinf(Point4f p1)
Computes the L-infinite distance between this point and point p1.
