Broad-phase collision detection methods?
I'm building a 2D physics engine and I want to add broad-phase collision detection, though I only know of 2 or 3 types:
Check everything against everything else (O(n^2) complexity)
Sweep and Prune (sort and sweep)
something about Binary Space…

What technique should be used to prune 2d collision checks?
From the outset, collision detection feels like it is an O(n^2) problem.
You have a bunch of objects and you need to check if each object is colliding with any of the other objects. However, I know that it is wildly ineffecient to check each…

Broad Phase Collision Detection - Methods In Comparison
First hey and thanks to everyone who views my question,
Im building a 3D-Physics engine for witch i need a broad phase collision detection system. The world i need this for is very specific and i compared some approaches and i'm still unsure what's…

Performance problems in sort and sweep pair reporting
I'm trying to write a sort and sweep broadphase system, and I've run into some performance problems, during the overlap reporting stage.
My pair reporting code is where the bottleneck is:
The basic Idea, is to generate a temporary list of overlap…
