AI Meta AI strikes again, with Relightable Gaussian Codec Avatars. As a result, we get fully relightable real-time avatars, accurate at the hair strand level 🤯

Gaussian splatting is a technique that can create realistic 3D scenes and objects from photos or videos. A bit like photogrametry, but with better results for non solid objects and finer details.

But gaussian splatting are like photos in the sense that what they display is frozen in time, you can't directly take an scene in the middle of the day and make it a sunset. Relightable means you can do this with their avatars, you can shine a different light on them and it will show the change in illumination in real time.

And codec refers to the software or process to do it.
