 # DanceNet3D
 
 
-A large-scale synchronized multi-view dance dataset captured with 28-29 calibrated cameras at 800x1280 resolution. The dataset contains 47 dance sequences across 3 recording sessions, totaling **35,509 frames** with per-frame camera calibration (COLMAP), foreground masks, optional color correction LUTs, and per-frame 3D Gaussian Splatting reconstructions (see [Extract 3DGS](#extract-3dgs)).
+A large-scale synchronized multi-view dance dataset captured with 28-29 calibrated cameras at 800x1280 resolution. The dataset contains 46 dance sequences across 3 recording sessions, totaling **34,698 frames** with per-frame camera calibration (COLMAP), foreground masks, optional color correction LUTs, and per-frame sparse point cloud reconstructions.

-Pre-computed 3D Gaussian Splatting (3DGS) reconstructions are available under the `/3dgs` directory. Each `.zip` file corresponds to one dance sequence and contains multiple `.ply` files — one per frame.
+Per-frame sparse point clouds are available under the `pointcloud/` directory. Each `.tar.zst` archive contains one `.ply` file per frame, named by frame ID (e.g., `0000001.ply`).

-On Mac, you can also double-click the `.zip` file in Finder. On Windows, right-click and use a tool like 7-Zip or WinRAR.
