AMD has announced a multithreaded CPU library for deformable material physics, using the Finite Element Method (FEM), called FEMFX. The model supports a wide range of materials and interactions between materials. Moreover, this CPU library is currently available for download.
According to the red team, the library uses extensive multithreading to utilize multicore CPUs and benefit from the trend of increasing CPU core counts. The system is also designed with the following considerations:
- Fidelity: realistic-looking wood, metal, plastic, even glass, because they bend and break according to stress as real materials do.
- Deformation effects: non-rigid use cases such as soft-body objects, bending or warping objects. It is not just a visual effect, but materials will resist or push back on other objects.
- Changing material on the fly: you can change the settings to make the same object behave very differently, e.g., turn gelatinous or melt.
- Interesting physics interactions for gameplay or puzzles.
Here are the key features of FEMFX:
- Elastic and plastic deformation
- Implicit integration for stability with stiff materials
- Kinematic control of mesh vertices
- Fracture between tetrahedral faces
- Non-fracturing faces to control shape of cracks and pieces
- Continuous collision detection (CCD) for fast-moving objects
- Constraints for contact resolution and to link objects together
- Constraints to limit deformation
- Dynamic control of tetrahedron material parameters
- Support for deforming a render mesh using the tetrahedral mesh
Developers can download the FEMFX library and sample code from here. The Unreal Engine plugin is also available here.

Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2.

that is excellent
Next month MS will release final version of DXR 1.1 SDK in Windows 2020 with support of physics. It is really nice that RT cores will be used not only for ray tracing but also for physics and other scenarios with lots of “ray collisions:. Can’t wait for DXR Havok

A solution that doesn’t need dedicated hardware is nice for the industry as a whole.
Oh yes more software rendering is good for the industry so that your CPU has more tasks to handle on top of Denuvo and other threads. Why use hardware rendering on GPUs when we can centralize and have everything being handled by the CPU?
Actually a good question as in gaming the GPU is already busier then anything and in the newer consoles they are going to FINALLY have CPU’s worth talking about something that hasn’t happen in like….ever
It’s 2019 – of course it’s called FEMFX 😉
if it would be called MANFX it would work better
Great!
Looks really cool and runs on CPU only…Im sure Ryzen 3000 series CPUs would handle the multithreading like a champ!
soooo non devs have no use of this? Right?
Anyone download it and try?!?
Going to attempt to today. Already have been jamming on UE4 to try and get an understanding of it. Hopefully I can get this to work…
