OuroWorld Dataset
Released data of OuroWorld: Bringing Any 3D World Alive as Diverse, Endlessly Looping 3D Cinemagraphs

1 National Yang Ming Chiao Tung University 2 Alaya Lab † Corresponding authors
OuroWorld turns a static 3D Gaussian Splatting (3DGS) scene from any source (a reconstruction, or a 3D world model such as HY-World 2.0, Marble or Lyra 2.0) into a 3D cinemagraph: a dynamic scene with vivid, diverse motion that loops endlessly and can be viewed from moving cameras.
This repository holds the data of the paper's 39 scenes: the cameras and pivots that define each scene's reference view, the looping reference videos (Seedance 2.0) that drive OuroWorld, the naturalness reference videos (MiniMax-H3) used by the KVD metric, and our rendered loop videos under an anchor and an orbit camera.

About the 3DGS Scenes
The input static 3DGS scenes (point_cloud.ply) are not included. The
scenes of HY-World 2.0, Marble and Lyra 2.0 come from 3D world models whose
licenses do not allow us to redistribute them, so we release the cameras,
pivots and reference renders of every scene but not the Gaussians themselves.
The scenes can be obtained from their original sources (the public galleries of HY-World 2.0 and Marble, the official code of Lyra 2.0, and the Mip-NeRF 360 dataset trained with the official 3DGS code for 30k iterations) and imported with the importers of the OuroWorld code.
If you run into any problem obtaining the scenes for evaluation or for reimplementing our method, please contact us and we will be glad to help.
Download
huggingface-cli download YouZhe/OuroWorld-dataset --repo-type dataset --local-dir data
Only part of it, e.g. the cameras and the reference videos:
huggingface-cli download YouZhe/OuroWorld-dataset --repo-type dataset --local-dir data \
--include "3dgs/*" "refvideo/*"
The video metadata can also be loaded with 🤗 Datasets:
from datasets import load_dataset
refvideo = load_dataset("YouZhe/OuroWorld-dataset", "reference_videos", split="train")
naturalness = load_dataset("YouZhe/OuroWorld-dataset", "naturalness_videos", split="train")
Usage with the OuroWorld Code
The layout matches the data/ folder expected by the OuroWorld code.
- Rerunning a scene of the paper. Put the scene's static 3DGS at
data/3dgs/<dataset>/<scene>/point_cloud.ply(INRIA 3DGS layout, in the coordinates of the released cameras), thenbash scripts/run_released.sh <dataset> <scene>. It reuses the paper's motion prompt and reference video fromdata/refvideo/, so no API key is needed. - Evaluation.
ouroworld-evaluate naturalnesscomputes KVD against the MiniMax-H3 videos indata/naturalness/<dataset>/<scene>/(configs/evaluation.yaml). Our videos indata/render/are the "Ours" rows of Table 2.
Metadata Files
refvideo/metadata.jsonl, one row per reference video:
{"file_name": "Marble/world/raw.mp4", "dataset": "Marble", "scene": "world", "model": "Seedance 2.0",
"prompt": "...", "reference_image": "3dgs/Marble/world/reference.png",
"width": 1280, "height": 720, "fps": 24.0, "num_frames": 241, "duration": 10.042}
naturalness/metadata.jsonl, one row per MiniMax-H3 video:
{"file_name": "Marble/world/minimax_h3_seed_0000.mp4", "dataset": "Marble", "scene": "world",
"model": "MiniMax-H3", "seed": 0, "prompt": "...", "reference_image": "naturalness/Marble/world/reference.png",
"width": 1344, "height": 768, "fps": 24.0, "num_frames": 243, "duration": 10.125}
file_name is relative to the folder of the metadata.jsonl;
reference_image is relative to the repository root.
Camera Format
reference_camera.json is the reference view, from which the reference video
is generated:
{
"width": 1024,
"height": 576,
"K": [[295.6, 0.0, 512.0], [0.0, 295.6, 288.0], [0.0, 0.0, 1.0]],
"c2w": [[...], [...], [...], [0.0, 0.0, 0.0, 1.0]]
}
c2wis the 4×4 camera-to-world pose in the OpenCV convention (x right, y down, z forward), in the coordinates of the scene's 3DGS.Kis in pixels, with the principal point at the image centre.
pivot.json holds the pivot clicked on the scene, around which the reference
view is chosen and the orbit camera turns: world_xyz in 3DGS world
coordinates, and reference_pixel / depth on the camera it was clicked on
(reference_image_size).
License
The data in this repository is released under the MIT License. The reference videos were generated with Seedance 2.0 and the naturalness videos with MiniMax-H3, and are also subject to the terms of those services. The input 3DGS scenes are not redistributed and remain under the licenses of their original sources. The data is intended for research use.
