Real-time 3D rendering is entering a new era! The latest research by Google's team, SMERF, can achieve real-time rendering of large 3D scenes on mobile devices and computers. Large scene rendering in 3D can now be done with just one computer or even a mobile phone. From the living room to the master bedroom, storage room, kitchen, and even the bathroom's corners, all can be rendered realistically on a computer, just like filming an actual video. SMERF is a method based on NeRFs, relying on a memory-efficient MERF. Researchers from Google and others have combined a hierarchical model partitioning scheme.
