Newton Game Dynamics
Newton Game Dynamics is an open-source physics engine for realistically simulating rigid bodies in games and other real-time applications. Its solver is deterministic and not based on traditional LCP or iterative methods. Newton Game Dynamics is actively developed by Julio Jerez. Currently a new version which will take advantage of multi-core CPUs and GPUs is being developed. Games that used Newton
