Anyone have a nice method to determine if two rectangles in 2D overlap? I actually want this for 3-D boxes, but I figure the 2D case will generalize. I currently determine the rectangle of intersection. If it exists then there is overlap. This doesn't seem elegant, and is pretty slow. Thanks, pete shirley shirley@m.cs.uiuc.edu
