刚刚，李飞飞发布世界模型新成果！一张图生成3D世界，现在就能玩

Core Viewpoint - World Labs, founded by Stanford professor Fei-Fei Li, has launched a beta version of its platform Marble, which allows users to create and explore 3D worlds using advanced AI technology [5][7]. Group 1: Technology and Features - Marble utilizes a 3D world generation model that can create vast and detailed environments based on a single photo, estimating depth maps and geometric boundaries [11][12]. - The generated 3D worlds are permanent, consistent, and feature clearer geometric structures compared to previous technologies [14]. - Users can export their created worlds as Gaussian splats and integrate them into web-based 3D experiences using the open-source rendering library Spark [14][16]. Group 2: User Experience - Users can navigate the AI-generated 3D spaces using keyboard and mouse controls, similar to first-person gaming experiences [16]. - The platform currently offers various demo scenes that showcase different indoor and outdoor environments, with impressive detail and realism in lighting and textures [17]. Group 3: Market Position and Future Potential - While Marble has made significant advancements, it is still in the early stages of commercial application, focusing primarily on 3D environments without the capability to generate characters or animals [19]. - The emergence of Marble coincides with a growing interest in AI gaming, as other companies like xAI are also venturing into AI-driven game development [26]. - The overall trend indicates a shift towards enabling users to easily create complex virtual worlds and gaming experiences, positioning AI as a tool for personal creativity and exploration [28][29].
