To See a World in a Living Context: Unified Indoor-Outdoor Urban World Generation
HoloWorld ties generated building interiors to the specific exteriors and footprints they belong to.
The paper describes a text-driven 3D generation framework that keeps a continuously updated world context from city layout down to individual buildings. It generates exterior blocks autoregressively, using neighboring blocks to preserve spatial organization and visual identity. Those exteriors are grounded in 3D building instances and footprints, which then constrain the corresponding indoor layouts and appearance. The authors report better exterior generation scores than prior systems, including a 7.68% average AQS gain over the cited state of the art. HF Daily Papers' note
