NVIDIA and Stanford Unveil World from Motion: Generative 4D Gaussian Reconstruction from a Single Video

ZGojcic · x · 2026-10-19

• World from Motion has been accepted by NeurIPS 2026, a collaboration between NVIDIA AMRI and Stanford (authors include Liyuan Zhu, Zan Gojcic, and Alex Trevithick).
• Core idea: leverage generative priors in 4D reconstruction to complete unseen regions and dynamics while respecting projection-geometry constraints, reconstructing a dynamic 3D Gaussian scene with freely renderable viewpoints from monocular video.
• The team has open-sourced the code, model weights, and DyCheck reproduction scripts (Apache-2.0); the project page is on the NVIDIA research site, and the repo includes full reproduction docs and a Docker environment.
• The conference will be held in Sydney.
