✨ A controllable video world model with explicit 4D geometric control over camera and multi-object motion.

TL;DR

• Dynamic Realistic Video World Model: VerseCrafter learns a realistic and controllable video world prior from large-scale in-the-wild data, handling challenging dynamic scenes with strong spatial-temporal coherence.
• 4D Geometric Control: A unified 4D control state provides direct, interpretable control over camera motion, multi-object motion, and their joint coordination, improving geometric faithfulness.
• Frozen Video Prior + GeoAdapter: We attach a geometry-aware GeoAdapter to a frozen Wan2.1 backbone, injecting 4D controls into diffusion blocks for precise control without sacrificing video quality.
• VerseControl4D Dataset: We introduce a large-scale real-world dataset with automatically rendered camera trajectories and multi-object 3D Gaussian trajectories to supervise 4D controllable generation.
