...ng, wouldn't a sweep and prune algorithm work better? the balls are moving fast, so any partitioning will have to be updated frequently, incurring overhead. A sweep and prune could find all colliding pairs in O(n log n), without any transient data structures. Here is a good tutorial for the basics
