OuroWorld: Bringing Any 3D World Alive as Diverse, Endlessly Looping 3D Cinemagraphs
OuroWorld transforms static 3D Gaussian Splatting scenes into dynamic, mask-free 3D cinemagraphs with diverse, looping motion from any viewpoint. It achieves this by using a vision-language model to infer dynamics for reference videos, then synthesizing multi-view videos. The core innovation is Inconsistency-Robust Periodic 4DGS, which uses a Fourier deformation field and a Grounded Drift Field to guarantee seamless looping and handle cross-view inconsistencies.
