Description: YGGDRASIL introduces a novel 3D scene graph architecture that efficiently handles both generating and consuming 3D data. It uses a layer-first hierarchical graph structure built from generic nodes and edges, allowing for direct semantic and spatial queries with low latency. This design avoids slow intermediate conversion steps, significantly speeding up tasks like trajectory prediction.
