World Labs Open-Sources Spark 2.0: Browser-Based Rendering of 100M+ 3D Gaussian Points

World Labs·medium signal

Fei-Fei Li's World Labs released Spark 2.0, an open-source 3D Gaussian Splatting rendering engine that streams large 3D worlds directly in web browsers including mobile and VR. The engine integrates with THREE.js and uses WebGL2 to render over 100 million Gaussian points on any device without specialized hardware. For builders, this unlocks real-time 3D scene streaming at a scale previously impossible outside dedicated native applications.
