WorldClaw: Agentic 3D Open-World Generation at Scale

The paper introduces WorldClaw, a fully agentic, coarse-to-fine framework for open-world 3D scene generation. Planning agents decompose a text prompt into a structured specification of regions, terrain, assets, and materials, ensuring global spatial coherence while maintaining rich local content. The system explicitly generates assets that can be reused or edited, moving beyond monolithic scene outputs. This approach could significantly improve scalability and practicality for virtual world creation in gaming, simulation, and interactive media. The arXiv paper (2608.05248v1) outlines the architecture and preliminary results, but further evaluation and comparisons with existing methods are expected.
