PanoWorld: A Generative Spatial World Model for Consistent Whole-House Panorama Synthesis

Researchers introduced PanoWorld, a generative spatial world model for consistent whole-house panorama and VR tour creation.

It synthesizes multi-room 360-degree views in sequence using floorplan-derived 3D geometry and dynamic visual memory.

The system uses room-aware group attention and topology-aware caching to preserve layout, materials, and cross-room consistency.

PanoWorld aims to make AI-generated virtual tours more realistic, coherent, and practically usable.
