Class BoundingBox2d

java.lang.Object
org.jzy3d.maths.BoundingBox2d
public class BoundingBox2d extends Object
A BoundingBox2d stores a couple of maximal and minimal limit on each dimension (x, y). It provides functions for enlarging the box by adding coordinates or an other BoundingBox2d (that is equivalent to computing the union of the current BoundingBox and another one).
