A Multi-Platform Physics Solution

The NVIDIA PhysX SDK is a scalable multi-platform physics solution supporting a wide range of devices, from smartphones to high-end multicore CPUs and GPUs. PhysX is already integrated into some of the most popular game engines, including Unreal Engine, and Unity3D.

The PhysX SDK is now open source, available under a BSD 3 license. With access to the source code, developers can debug, customize and extend the PhysX SDK as they see fit.
