Research overview
From sensing the physical world to building intelligent, interactive digital worlds.
At a high level, our work asks one question: how can machines faithfully understand, reconstruct and generate people and environments across space and time? We connect computer vision, computer graphics, generative AI and numerical optimization to transform images, videos, audio and geometric observations into structured, controllable 3D/4D representations.
Our vision
We envision world models that are geometrically grounded, physically plausible and human-aware—systems that can perceive the real world, imagine how it may evolve, and create digital experiences in which people can naturally interact, communicate and explore.
研究简介
从感知真实世界，到构建智能、可交互的数字世界
从更高层面看，我们关注一个核心问题：如何让机器跨越空间与时间，真实地理解、重建并生成“人”与“环境”？我们融合计算机视觉、计算机图形学、生成式人工智能与数值优化，将图像、视频、语音和几何观测转化为结构化、可控制的三维/四维表达。
我们的愿景
构建具有几何基础、符合物理规律并能理解人的世界模型：它既能感知现实、推演世界如何变化，也能创造让人自然交流、互动和探索的数字体验。
