Fast 4x4 Matrix Inverse with SSE SIMD, Explained

Recommended Posts

Hi guys,

I'm writing my math library and implemented some matrix inverse function I would like to share.

The SIMD version I got is more than twice as fast as non-SIMD version (which is what Unreal is using). It is also faster than some other math libraries like Eigen or DirectX Math.


(result from my test, the first 3 columns are my methods)


If you are interested in either theory or implementation, I put together my math derivation and source code in this post:


I would appreciate any feedback :)
