NVIDIA PhysX Engine Now is Open-Source
NVIDIA PhysX is going open source. NVIDIA is doing this because physics simulation - long key to immersive games and entertainment - turns out to be more important than we ever thought. Physics simulation dovetails with AI, robotics and computer vision, self-driving vehicles, and high-performance computing.
It’s foundational for so many different things we’ve decided to provide it to the world in an open source fashion. Meanwhile, we’re building on more than a decade of continuous investment in this area to simulate the world with ever greater fidelity, with on-going research and development to meet the needs of those working in robotics and with autonomous vehicles. PhysX will now be the only free, open-source physics solution that takes advantage of GPU acceleration and can handle large virtual environments.
It will be available as open source starting Monday, Dec. 3, under the simple BSD-3 license.
PhysX solves some serious challenges.
- In AI, researchers need synthetic data — artificial representations of the real world — to train data-hungry neural networks.
- In robotics, researchers need to train robotic minds in environments that work like the real one.
- For self-driving cars, PhysX allows vehicles to drive for millions of miles in simulators that duplicate real-world conditions.
- In game development, canned animation doesn’t look organic and is time consuming to produce at a polished level.
- In high-performance computing, physics simulations are being done on ever more powerful machines with ever greater levels of fidelity.
PhysX SDK addresses these challenges with scalable, stable and accurate simulations. It’s widely compatible, and it’s now open source. PhysX SDK is a scalable multi-platform game physics solution supporting a wide range of devices, from smartphones to high-end multicore CPUs and GPUs. It’s already integrated into some of the most popular game engines, including Unreal Engine (versions 3 and 4) and Unity3D.
You can also find the full source code on GitHub. Dig in.

Cool, now I can get rid of my GT1030 (GDDR5) for those few Physx games (Batman games, Borderlands 1 and 2. Can't think of any recent game with it). :p

My opinion is that they are releasing it because they can no longer milk customers with it.

How exactly were they milking customers with it when the SDK & platform has always been free?
Also the source has been available since 2015 via their github - the only difference here is that it's now available via an open license...

@ManofGod This is very likely indeed. It is also possible that other physic engine solutions are used by modern video game titles and upcoming games, so they want to try out if some developers get interested in PhysX again, so any software using PhysX would run smoother on their hardware. This logic also applies on the other mentioned usecases, so Nvidia's hardware would be used in all situations to make PhysX run without major performance penalty or to have easier time when programming PhysX to work with the hardware. The reason for this whole move is to sell their hardware.

I don't want to hear any more excuses from AMD now that it has been open sourced.

The source has been available for three years...
What does this have to do with the software always being free and source being available for three years? lol.. Anyone can write an OpenCompute physics middleware and publish it. Nvidia isn't controlling that.
PhysX is the default physics implementation in Unity & Unreal. It's by far the most popular physics engine. They are releasing 4.0 SDK soon and it seems like the choice to move it to an open license coincides with that. You're kind of right about the hardware though as one of the mean features is BVH support for fast queries - BVH performance is one of the major changes in Turing architecture as part of the RT core.
So yeah I think it's about renewing interest in the new SDK but in reality there isn't much going on here that wasn't already available.

@Denial Did you mean OpenCL/DirectCompute? Anyway, it is not like anyone sane expects any PhysX game to be working well on any platform.

But we're getting a Radeon voice assistant, something we all wanted. /s

i can go on about this open source code being released later than earlier, but 1) it's obvious, and 2) it's a good thing regardless.
kudos to Nvidia

Nice, hopefully AMD will add support to their cards now.
