static int [] shapes3d.utils.Util.box_box_p	(	int	ax0,
		int	ay0,
		int	ax1,
		int	ay1,
		int	bx0,
		int	by0,
		int	bx1,
		int	by1
	)

static

If two boxes overlap then the overlap region is another box. This method is used to calculate the coordinates of the overlap.
The boxes are represented by the top-left and bottom-right corner coordinates. If the returned array has a length: 0 then they do not overlap
4 then these are the coordinates of the top-left and bottom-right corners of the overlap region.

Parameters

ax0	top-left corner of rectangle A
ay0	top-left corner of rectangle A
ax1	bottom-right corner of rectangle A
ay1	bottom-right corner of rectangle A
bx0	top-left corner of rectangle B
by0	top-left corner of rectangle B
bx1	bottom-right corner of rectangle B
by1	bottom-right corner of rectangle B

Returns: an array with the overlap box coordinates (if any)
