OccDirector: Language-Guided Behavior and Interaction Generation in 4D Occupancy Space
arXiv CS.CV

ArXi:2604.22240v1 Announce Type: new Generative world models increasingly rely on 4D occupancy for realistic autonomous driving simulation. However, existing generation frameworks depend on rigid geometric conditions (e.g., explicit trajectories) or simplistic attribute-level text, failing to orchestrate complex, sequential multi-agent interactions. To address this semantic-spatiotemporal gap, we propose OccDirector, a pioneering framework that generates 4D occupancy dynamics conditioned solely on natural language.
