SIMD Matters :: Box2D
SIMD in game development Often in game development we talk about SIMD. It is the holy grail of CPU performance, often out of reach. The conventional wisdom is that it is difficult to achieve real gains from SIMD. It is tempting to build a math library around SIMD hoping to get some performance gains. However, it often has no proven benefit. It just feels good to be using something we know can improve performance.
Releasing Box2D 3.0 :: Box2D
Over 18 months ago I announced that I was working on Box2D version 3.0 (v3 for short). And it has finally arrived! It has been a long journey and I've learned a lot. There is more work to do, but the library is ready to be used for game development. I'd like to thank the Box2D users who tested v3 during the alpha and beta. Their feedback and bug reports have been super helpful!

Simulation Islands :: Box2D
Island management is a fundamental low level feature of physics engines and can have a big impact on solver design and performance. This was one of the first problems I decided to work on for Box2D version 3 (v3). Since I began working on v3 I've been comparing several algorithms for island management. My goal has been to make island building scale better with multiple CPU cores. Here are the three approaches I've considered:
