World Labs, a company founded by Fei-Fei Li, has open-sourced Spark 2.0, a 3D Gaussian sputtering rendering engine.

World Labs, under Fei-Fei Li's company, has open-sourced Spark 2.0, a 3D Gaussian sputtering rendering engine that supports streaming over 100 million splats of 3D worlds to desktops, mobile phones, and VR devices via WebGL2. Built on Three.js, the engine employs continuous LoD Gaussian sputtering trees, progressive streaming, and virtual memory technologies to achieve real-time rendering of ultra-large-scale scenes on web pages, addressing the pain points of traditional engines such as supporting only single objects, lack of dynamic animation, and poor device compatibility.
