Collision detection (part 2): Box intersection

Posted on January 18, 2015 by mikolalysenko

Last time, we discussed collision detection in general and surveyed some techniques for narrow phase collision detection.  In this article we will go into more detail on broad phase collision detection for closed axis-aligned boxes.  This was a big problem in the 1970’s … Continue reading →
