SMERF technology, launched by the Google team, enables real-time rendering of realistic 3D scenes within a 300 square meter room. It supports ordinary smartphones and laptops, offering 60fps real-time rendering and full six degrees of freedom navigation. Utilizing layered models and distillation training strategies, it addresses the performance and quality challenges of large 3D scenes. Users can freely move within the 3D scenes, with generated images approaching photo-realistic fidelity. SMERF technology provides a more realistic and smooth 3D experience without the need for expensive equipment, requiring only standard smartphones and laptops.
