Sort, sweep, and prune: Collision detection algorithms The problem of collision detection is pretty common in video game programming. It’s a prerequisite to the implementation of certain game mechanics or simulations. Here I’ll cover several related approaches, starting with the simplest and building up to the sweep-and-prune algorithm. I won’t cover other approaches, such as space partitioning or spatial tree subdivision.
