OuroWorld: Bringing Any 3D World Alive as Diverse, Endlessly Looping 3D Cinemagraphs

OuroWorld is a mask‑free framework that transforms any static 3D Gaussian Splatting scene into a 3D cinemagraph, producing dynamic scenes with vivid, diverse motion that loop seamlessly from any viewpoint. It uses a vision‑language model to infer plausible dynamics and a video model to synthesize a reference video, which is then lifted and completed into multi‑view videos. The method introduces an Inconsistency‑Robust Periodic 4DGS with a Fourier‑series deformation field for guaranteed looping and a Grounded Drift Field to handle cross‑view inconsistencies, enabling general deformation, object motion, and illumination change beyond fluid‑like motion. Evaluation on 39 scenes shows OuroWorld outperforms baselines and wins 70.8%–99.0% of user‑study comparisons.
