Aion: Towards Hierarchical 4D Scene Graphs with Temporal Flow Dynamics

ArXi:2512.11903v2 Announce Type: replace-cross Autonomous navigation in dynamic environments requires spatial representations that capture both semantic structure and temporal evolution. 3D Scene Graphs (3DSGs) provide hierarchical multi-resolution abstractions that encode geometry and semantics, but existing extensions toward dynamics largely focus on individual objects or agents.
