NVIDIA Makes PhysX & Flow GPU Code Open-Source. (github.com)

Since the release of PhysX SDK 4.0 in December 2018, NVIDIA PhysX has been available as open source under the BSD-3 license—with one key exception: the GPU simulation kernel source code was not included.

That changes today.

We’re excited to share that the latest update to the PhysX SDK now includes all the GPU source code, fully licensed under BSD-3!

With over 500 CUDA kernels powering features such as rigid body dynamics, fluid simulation, and deformable objects, GPU PhysX represents one of the most advanced real-time simulation use cases of CUDA and GPU programming. We hope this release will be a valuable resource for learning, experimentation, and development across the community.

In addition, we’re also open-sourcing the full GPU compute shader implementation of the Flow SDK, our real-time, sparse grid–based fluid simulation library.

If only, this is "modern" PhysX, we'd need the source to the original Ageia PhysX 2.X branch to fix it properly.
