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

Key points

• Recent 3D world models generate photorealistic, explorable scenes that remain frozen in time.1
• To learn from this imperfect supervision, we propose Inconsistency-Robust Periodic 4DGS: a Fourier-series deformation field guarantees looping by construction, while a Grounded Drift Field anchored at the reference view absorbs cross-view inconsistency.1
• Unlike prior Eulerian methods limited to fluid-like motion, we capture general deformation, object motion, and illumination change.1
• We introduce a ground-truth-free evaluation covering vividness, naturalness, loop seam coherence, and scene quality.1

  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.
