Method Detail

xCompare

public int xCompare(BoundingBox box)

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

Parameters:

box - a BoundingBox

Returns:

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

public boolean isIntersecting(BoundingBox box)

Parameters:

box - a BoundingBox

Returns:

true if this BoundingBox and the box have an intersection

isStrictlyIntersecting

public boolean isStrictlyIntersecting(BoundingBox box)

Parameters:

box - a BoundingBox

Returns:

true if this BoundingBox and the box have a strict intersection

getBoundingBox
