Stereo World Model: Camera-Guided Stereo Video Generation
TLDR
A camera-conditioned stereo world model for end-to-end stereo video generation with improved consistency and efficiency.
Reasoning
The paper introduces novel camera-frame RoPE and stereo-aware attention decomposition, achieving strong results on benchmarks and real-world applications like VR rendering and embodied learning. However, it lacks explicit evaluation on interactive or dynamic prediction tasks, and the term 'world model' is used loosely without full dynamics modeling.

Innovations
- Unified camera-frame RoPE that augments latent tokens with camera-aware rotary positional encoding for relative, view- and time-consistent conditioning while preserving pretrained video priors via stable attention initialization
- Stereo-aware attention decomposition that factors full 4D attention into 3D intra-view attention plus horizontal row attention, leveraging epipolar prior for disparity-aligned correspondences with lower compute
Methodology
StereoWorld is a camera-conditioned stereo world model that jointly learns appearance and binocular geometry for end-to-end stereo video generation, operating exclusively in RGB modality while grounding geometry from disparity. It uses a unified camera-frame RoPE for conditioning and a stereo-aware attention decomposition to efficiently capture disparity-aligned correspondences.
Key Results
StereoWorld improves stereo consistency, disparity accuracy, and camera-motion fidelity over monocular-then-convert pipelines, achieving more than 3x faster generation with an additional 5% gain in viewpoint consistency.
