WorldCrafter: Consistent Video World Model with Implicit 3D-aware Memory

WorldCrafter is a video world model that learns a camera-queryable implicit 3D-aware memory to preserve consistency across long horizons and viewpoints during interactive scene exploration. A memory encoder and pose-conditioned readout module, trained jointly with the video generator, compress multi-view historical observations into fixed target-view-specific tokens without explicit depth-based correspondences, and combined with few-step distillation enable streaming exploration from a single image or text prompt with improved long-horizon consistency and camera-control accuracy.
