Comment on Show HN: HTML5 Bird Flocks Simulation in CoffeeScriptparentComments−chris_pOP13yIt's the number of neighbors each boid considers to calculate its velocity. There's also an option that defines the maximum distance for collision detection, but it's not accessible through the UI.−hythloday13yThanks! The canonical data structure to avoid the O(n^2) lookup is a kdtree, which I think is reasonably easy to implement in coffeescript.
