NuiScene43 Dataset

The NuiScene43 dataset offers a curated collection of moderate to large artist-created outdoor scenes, filtered from Objaverse, for training and testing unbounded scene generation methods. We manually unified the scene scales and ground geometry to enable consistent joint training across all 43 scenes. This repo includes the preprocessed occupancy grid and point cloud sampled from scenes for training NuiScene. Please see the dataset page for renderings of the 43 scenes, also the paper or project page for more details.
