## At a glance

- Spark 2.0 supports streaming 3D scenes with over 100 million splats to multiple devices via WebGL2
- Uses continuous LoD trees and virtual memory to solve pain points in large-scale real-time web rendering

## The update

World Labs, founded by Fei-Fei Li, has officially open-sourced Spark 2.0, a next-generation 3D Gaussian Splatting rendering engine. Built on Three.js, its core breakthrough lies in supporting the real-time streaming of massive 3D worlds containing over 100 million splats to desktops, smartphones, and VR headsets via WebGL2. To address pain points of traditional engines, such as single-object limitations, lack of dynamic animation, and poor device compatibility, Spark 2.0 introduces advanced technologies including continuous LoD Gaussian Splatting trees, progressive streaming loading, and virtual memory. These innovations enable efficient, real-time rendering of ultra-large-scale scenes in web browsers, significantly enhancing the expressiveness and usability of 3D content in web environments.
