1 if box is on the right, -1 if on the left and 0 if nothing.

yCompare

public int yCompare(BoundingBox box)

Get the relative y-position of this bounding-box and of the box

Parameters:

box - a BoundingBox

Returns:

1 if box is on the bottom, -1 if on the top and 0 if nothing.

zCompare

public int zCompare(BoundingBox box)

Get the relative z-position of this bounding-box and of the box

Parameters:

box - a BoundingBox

Returns:

1 if box is on the front, -1 if behind and 0 if nothing.

isIntersecting
