WoVoGen: World Volume-aware Diffusion for Controllable Multi-camera Driving Scene Generation
TLDR
WoVoGen uses 4D world volume to generate consistent multi-camera driving videos from vehicle control inputs.
Reasoning
The paper introduces a novel two-phase diffusion framework leveraging explicit 4D world volume for intra-world and inter-sensor consistency. Strengths include addressing key consistency challenges in multi-camera generation, while weaknesses are the lack of explicit real-world evaluation or benchmark results in the abstract.

Innovations
- Combining an explicit 4D world volume as a foundational element for multi-camera driving scene video generation
- Two-phase generation pipeline: first envisioning future 4D temporal world volume from vehicle control sequences, then generating multi-camera videos conditioned on that volume and sensor interconnectivity
- Controllable generation via vehicle control inputs and support for scene editing tasks
Methodology
WoVoGen operates in two phases: (i) it envisions a future 4D temporal world volume based on vehicle control sequences, and (ii) it generates multi-camera videos informed by this envisioned 4D world volume and sensor interconnectivity. The model leverages diffusion-based generation and incorporates an explicit world volume representation to ensure intra-world consistency and inter-sensor coherence.
Key Results
The system generates high-quality street-view videos in response to vehicle control inputs and facilitates scene editing tasks, demonstrating the effectiveness of the 4D world volume approach.
