Overview
Imagine transforming a single photograph, sketch, or text description into a fully navigable, persistent 3D world that you can revisit, edit, and expand indefinitely. Marble by World Labs makes this vision achievable, powered by a sophisticated multimodal world model that accepts diverse creative inputs—images, videos, text prompts, 3D layouts, and panoramic photographs—to generate spatially consistent, high-fidelity 3D environments. Founded by AI pioneer [translate:Fei-Fei Li] and developed by spatial intelligence researchers, Marble democratizes complex 3D world creation, making advanced environment generation accessible to creators, developers, game studios, and visual effects professionals without requiring expertise in traditional 3D modeling tools.
Key Features
Marble integrates cutting-edge world modeling with creator-focused workflows to deliver comprehensive 3D world-building capabilities.
- Massively Multimodal World Model: Accept diverse creative inputs including text prompts, single or multiple images, video clips, 3D layout sketches, and 360-degree panoramic photographs, offering unprecedented flexibility in how you initiate world creation.
- Persistent, High-Fidelity 3D Worlds: Generate detailed, spatially consistent 3D environments that maintain coherence and can be revisited, edited, expanded, and refined over time, supporting iterative creative development rather than one-off generation.
- Chisel AI-Native Editing Tool: An experimental 3D editor enabling users to sketch rough spatial structures using basic shapes (boxes, planes) or imported 3D assets, then supply text descriptions of visual style—allowing Marble to complete scenes by separating structural control from visual detail generation.
- Composition and Expansion Capabilities: Combine multiple worlds together through Composer mode to build expansive environments, or use Click and Expand to grow existing worlds seamlessly beyond their original boundaries.
- Professional Export Formats: Download generated worlds as Gaussian splats (full-resolution 2-million-splat or lightweight 500k versions), standard polygon meshes with collision geometry, or video files for seamless integration with game engines (Unity, Unreal), 3D software (Blender, Houdini), or web viewers.
- VR and Immersive Display Integration: Experience generated 3D worlds immediately in VR through Apple Vision Pro or Meta Quest 3, making Marble one of the first commercial world model products bridging AI generation directly to immersive display.

How It Works
Marble operates through an intuitive creation and refinement workflow designed for both rapid exploration and precise control. Users begin by providing a creative seed—a reference image capturing mood and setting, a short video depicting an environment from multiple angles, a text prompt describing desired features, a coarse 3D layout sketch, or a panoramic photograph. Marble’s multimodal world model processes this input, intelligently inferring structural elements, spatial relationships, visual appearance, lighting characteristics, and intricate environmental details. The system generates a complete, navigable 3D environment rendered as Gaussian splats—a neural representation that balances visual quality with interactive performance. Critically, this generated world persists: you can navigate through it, examine details from different angles, and return to it in future sessions. For users requiring precise creative control, the Chisel tool enables structural direction—users define coarse spatial layouts using basic geometric shapes or imported 3D assets, then supply text prompts specifying visual style and additional elements. Marble then completes the scene while respecting the structural framework. Once satisfied with an environment, users can expand specific regions to increase detail, combine multiple worlds into larger landscapes, and export results as Gaussian splats, polygon meshes, or videos for immediate integration into game engines, web viewers, or custom development pipelines.
