StateFlow: Building, Evolving, and Accessing 3D World States for Previsualization
StateFlow treats previsualization as an editable 3D world state, not a one-shot video generation task.
The paper argues that scenes, actions, cameras, and timing should persist as structured state across edits. StateFlow builds that state by lifting generated 2D content into a coherent 3D world, then evolves it through targeted state transitions instead of regenerating the whole scene. Its access stage uses render-feedback reflection to refine camera paths into visually feasible trajectories. The authors report high-quality 3D worlds for video creation and game-like prototyping.
