According to God of Prompt on Twitter, Huawei and Shanghai Jiao Tong University (SJTU) have introduced WorldGrow, an advanced AI system capable of generating infinite, seamless 3D environments from a single seed. Unlike traditional methods that rely on loops or stitching, WorldGrow uses a coarse-to-fine generation approach to maintain logical global layouts while preserving crisp local details. Its integrated 3D inpainting module ensures any missing regions are contextually filled, enabling AI agents to freely explore and interact within these dynamically created spaces. This technology opens up significant business opportunities for game development, virtual reality, autonomous robotics, and digital twin industries by enabling scalable, realistic world-building with minimal manual design.
