![]() ![]() On December 3, 2018, PhysX was made open source under a 3-clause BSD license, but this change applied only to computer and mobile platforms. The proprietary SDK was provided to developers for free for both commercial and non-commercial use on Windows, Linux, macOS, iOS and Android platforms. Īt GDC 2015, Nvidia made the source code for PhysX available on GitHub, but required registration at. PhysX SDK 3.0 was released in May 2011 and represented a significant rewrite of the SDK, bringing improvements such as more efficient multithreading and a unified code base for all supported platforms. Nvidia started enabling PhysX hardware acceleration on its line of GeForce graphics cards and eventually dropped support for Ageia PPUs. In 2008, Ageia was itself acquired by graphics technology manufacturer Nvidia. The first game to use PhysX was Bet On Soldier: Blood Sport (2005). Ageia called the technology PhysX, the SDK was renamed from NovodeX to PhysX, and the accelerator cards were dubbed PPUs (Physics Processing Units). In 2004, Ageia acquired NovodeX AG and began developing a hardware technology that could accelerate physics calculations, aiding the CPU. ![]() The engine was developed by Swiss company NovodeX AG, an ETH Zurich spin-off. What is known today as PhysX originated as a physics simulation engine called NovodeX. PhysX and other middleware physics engines are used in a large majority of today's video games because they free game developers from having to write their own code that implements classical mechanics (Newtonian physics) to do, for example, soft body dynamics. In both cases, hardware acceleration allowed for the offloading of physics calculations from the CPU, allowing it to perform other tasks instead. However, after Ageia's acquisition by Nvidia, dedicated PhysX cards have been discontinued in favor of the API being run on CUDA-enabled GeForce GPUs. ![]() Initially, video games supporting PhysX were meant to be accelerated by PhysX PPU ( expansion cards designed by Ageia). PhysX is an open-source realtime physics engine middleware SDK developed by Nvidia as a part of Nvidia GameWorks software suite.
