" 构建世界模型，为什么不能只靠「炼丹」？ " 作者丨吴彤 编辑丨 林觉民 在香港中文大学（深圳），助理教授韩晓光的实验室名为GAP，意为"像素、点与多边形的生成与分析"。 现在看来，这个名字，也隐喻着他希望弥合真实世界和虚拟世界之间的"鸿沟"的意思。 2018年，韩晓光加入这所大学时，是当时唯一专注于计算机图形学研究的教师。2024年，他尝试从三维 重建拓展至具身智能与世界模型，又一次如入无人之境。 在小红书上，他的账号@韩晓光，简介仅有两行：港中深理工学院助理教授、图形学与三维视觉。他将小 红书视为传播平台，也视为个人思考的整理场所，会公开讨论"显式3D是否还有必要"、"世界模型为何需 要可解释性"等专业问题，也会记录与学生讨论时获得的启发。 这种直接、平实的分享，吸引了一批对技术本质感兴趣的读者，也代表了韩晓光这类青年教师群体打破学 术边界的自觉实践。从某一种角度看，构建世界模型需要理解真实世界的运行逻辑，而他的线上互动，本 身就是一场持续进行的、小规模的"世界模拟"。 在韩晓光的叙述中，他研究演进是自然发生的。从三维重建到动态生成，再到服务于机器人的虚拟环境构 建，核心始终是"三维内容的生成与理解"。 ...
