This is amazing! Do you think it would be possible to integrate the full PhysX and add it as a second option to Ammo? This could be super useful to many.

Very nice work, many thanks for sharing! Did you run any performance comparison with Ammo.js for large dynamic scenes?

@pixelpros right, that may be done at some point in the future. We need to wait for better bindings coverage, at least to match the Ammo functionality.
@Leonidas thanks! The bindings are quite limited for now, so many features are simply lacking en emscripten bind. It would take some effort to expose additional bindings, so perhaps at some point later. Nevertheless, here is a stress test for comparison Ammo vs Cannon vs PhysX made by https://github.com/prestomation from Amazon team:

Unfortunately, the demo no longer seems to function properly.
I’m on Windows 10 and using Firefox.
It’s possible that the issue is because my Firefox version is a bit outdated.
My computer has enabled PhysX.

The project itself doesn’t work for me, but the live demo from the twitter link does work (https://twitter.com/xik_le/status/1330332234230927361).
What is the issue? I really like this to work.
The issue is that the project was using private engine API that has been changed since then. The project will need to be updated.
I’ve made a fix to this in a fork: https://playcanvas.com/project/837719/overview/playcanvas-with-nvidia-physx

hi yaustar,
i try your last physX project, but i’ve got this error message 
thank u for your help
I believe kinematics weren’t supported in the original project that LeXXik did.
The demo has a very limited feature set and was more of a tech demo by LeXXik. If you need more features, you will have to look at developing it further yourself unfortunately.
