NVIDIA Makes The PhysX 5.1 SDK Open-Source

Written by Michael Larabel in NVIDIA on 8 November 2022 at 10:17 AM EST. 46 Comments
Back in 2019 NVIDIA open-sourced the PhysX 4.1 SDK and was working on a PhysX 5.0 open-source code drop while we haven't heard anything more on the matter in the past two years. Coming out this morning as a surprise is the NVIDIA PhysX 5.1 SDK open-source release.

More than a decade ago NVIDIA bought Ageia as the company behind PhysX and at the time focused on trying to push physics accelerator cards for gaming. Since NVIDIA's acquisition, PhysX has been focused on GPU acceleration and for the once-proprietary SDK, more than a half-decade ago NVIDIA began open-sourcing it as far as the SDK and CPU paths are concerned.

Released today is the PhysX 104.0 / PhysX SDK 5.1 release. This amounts to a big 662k lines drop of code, documentation, and related assets.

For those interested in the NVIDIA PhysX SDK, the newly open-sourced code can be found via this GitHub repository.
