# X-Splat: Unified Gaussian Splatting for Joint RGB and X-ray 3D Reconstruction

SIGGRAPH Asia 2026 Conference Papers | [Project page](https://zezeaaa.github.io/X-Splat/) | [Code](https://github.com/zezeaaa/X-Splat)

Data for the X-Splat code: our insect scenes, our foreground masks for the InsideOut scenes, and our
trained models. How to use them is in the code's [DATA.md](https://github.com/zezeaaa/X-Splat/blob/main/DATA.md).

| File | Size | Contents |
|---|---|---|
| `xsplat_insect_processed.zip` | 605 MB | insect scene packages (E02, E15, E32), ready to train |
| `xsplat_insideout_mask_annotations.zip` | 2.4 MB | our foreground masks for the InsideOut scenes |
| `xsplat_checkpoints_and_results.zip` | 63 MB | our trained models (insect, Flower) and the metrics of all nine scenes |
| `SHA256SUMS.txt` | | checksums of the three archives |

```bash
# everything, into the code's data/ directory
hf download zezeaaa/X-Splat --repo-type dataset --local-dir data
# or a single archive
hf download zezeaaa/X-Splat xsplat_insect_processed.zip --repo-type dataset --local-dir data
cd data && unzip xsplat_insect_processed.zip
```

The InsideOut and Flower data are not included; DATA.md says where to get them.
