OuroWorld: Bringing Any 3D World Alive as Diverse, Endlessly Looping 3D Cinemagraphs
OuroWorld turns static 3D Gaussian Splatting scenes into endlessly looping, viewpoint-consistent 3D cinemagraphs.
OuroWorld is a mask-free method that converts a static 3D Gaussian Splatting scene into a looping 3D cinemagraph with diverse motion from any viewpoint. A vision-language model proposes plausible dynamics, a video model generates a reference, and that supervision is lifted into multi-view video. A Fourier-series deformation field enforces looping, while a Grounded Drift Field absorbs cross-view inconsistency. Across 39 reconstructed and generated scenes it outperformed baselines and won 70.8%–99.0% of user-study comparisons.
- A vision-language model infers dynamics and a video model synthesizes a reference clip.
- Inconsistency-Robust Periodic 4DGS uses a Fourier deformation field to force seamless loops.
- A Grounded Drift Field absorbs cross-view inconsistency while capturing general object motion.
- On 39 scenes it beats baselines and wins 70.8%–99.0% of user comparisons.

Recent 3D world models generate photorealistic, explorable scenes that remain frozen in time. OuroWorld is a mask-free framework that turns any static 3D Gaussian Splatting scene into a 3D cinemagraph: a dynamic scene with vivid, diverse motion looping seamlessly from any viewpoint.
