Marble – a 3D world generation platform launched by Fei-Fei Li’s World Labs

What is Marble？

Marble is a 3D world generation platform launched by Fei-Fei Li’s startup World Labs. Built on advanced world model technology, Marble allows users to generate infinitely explorable 3D worlds from just a single image or a text prompt. The generated worlds are persistent, stylistically diverse, and feature clear 3D geometric structures. Users can freely navigate and interact within them, and even export the results as Gaussian splats for downstream projects. Currently in a limited-access beta phase, Marble enables users to create and explore 3D worlds directly on its official website, showcasing powerful spatial intelligence and creative capabilities.

Key Features of Marble

3D World Generation: By uploading an image or entering a text prompt, users can quickly generate a 3D world. The worlds include rich geometric structures and a wide range of styles—from cartoon-like to photorealistic.
Free Navigation & Interaction: Users can move freely and explore generated 3D environments, with 360-degree perspective adjustment directly in the browser, including hidden areas beyond the input viewpoint.
Persistence & Consistency: Generated 3D worlds remain stable and consistent over time without deformation or drift. Users can revisit or share permanent links anytime.
Export Functionality: Worlds can be exported as Gaussian splats and seamlessly integrated into Three.js using World Labs’ open-source rendering library Spark, enabling web-based 3D experiences.
Composing Large Environments: Users can combine multiple generated scenes to build larger, continuous virtual worlds.
Multi-Platform Support: Generated experiences run efficiently across devices, including desktops, laptops, mobile devices, and VR headsets.
Creation & Sharing: Users can create their own 3D worlds and share them via Marble, fostering social interaction and creative exchange.
