EVENT DOSSIER
On September 7, 2026, Xiaobin Huang and others proposed a framework called HoloWorld, which was the first system capable of uniformly generating indoor and outdoor environments. This framework relies on continuously updated cross-scale world context, utilizes user-described initialization information, and generates urban appearances with spatial consistency through autoregressive methods. The appearances are then converted into 3D instances to constrain indoor layouts. Experimental results showed that HoloWorld’s average AQS score increased by 7.68% compared to state-of-the-art methods, achieving the highest RDR score while maintaining architectural-level indoor-outdoor correspondence and cross-block continuity.
Hugging Face HoloWorld 发布统一室内外城市世界生成框架
Xiaobin Huang 等提出 HoloWorld，首个统一室内室外生成框架，实现从城市规划到建筑内外的连贯 3D 世界生成。该框架基于持续更新的跨尺度世界上下文，利用用户描述初始化信息，通过自回归方式生成具有空间一致性的城市外观，并将外观落地为 3D 实例以约束室内布局。实验表明，HoloWorld 平均 AQS 分数较最先进方法提升 7.68%，获得最高 RDR 分数，同时保持了建筑级室内外对应及跨街区连续性。
