+# AnchorSplat Processed Third-Party Data
+
+Processed third-party MVImgNet data used by **AnchorSplat** for evaluation and comparison settings.
+
+The data is arranged in the Splatfacto/AnchorSplat loader layout. Extract each archive into the `data/` directory of the AnchorSplat repository.
+
+## Files
+
+| Archive | Scenes | AnchorSplat config | Description |
+| --- | ---: | --- | --- |
+| `mvimgnet_splatformer_ready.tar.zst` | 15 | `configs/dataset/mvimgnet.gin` | MVImgNet processed with low-resolution 3DGS input |
+| `mvimgnet_sginput_splatformer_ready.tar.zst` | 15 | `configs/dataset/mvimgnet_sginput.gin` | MVImgNet processed with SuperGaussian input |
+| `mvimgnet_sg4x_splatformer_ready.tar.zst` | 15 | `configs/dataset/mvimgnet_sg4x.gin` | MVImgNet processed with SuperGaussian 4x input |
+
+`DATA_MANIFEST.json` contains scene names and required-file checks. `SHA256SUMS.txt` contains archive hashes.
+
+## Download
+
+```bash
+huggingface-cli download de233/AnchorSplat-Processed-Third-Party-Data   --include "*.tar.zst" --include "DATA_MANIFEST.json" --include "SHA256SUMS.txt"   --local-dir data/processed_third_party_archives
+```
+
+## Extract
+
+```bash
+mkdir -p data
+for f in data/processed_third_party_archives/*.tar.zst; do
+  tar --zstd -xf "$f" -C data
+done
+```
+
+After extraction, the paths should look like:
+
+```text
+data/mvimgnet_splatformer_ready/<scene>/256/gaussian_splatting/ckpts/ckpt_14999_rank0.pt
+data/mvimgnet_splatformer_ready/<scene>/256/sparse/0/{cameras.bin,images.bin,points3D.bin}
+data/mvimgnet_splatformer_ready/<scene>/1024/images/*.png
+data/mvimgnet_splatformer_ready/<scene>/1024/{cameras.txt,images.txt}
+```
+
+## Evaluation
+
+```bash
+DATA_CONFIG=configs/dataset/mvimgnet.gin CHECKPOINT=checkpoints/anchorsplat_20x.pth GPUS=0 NPROC=1 bash scripts/evaluate_anchorsplat.sh
+```
+
+Replace `DATA_CONFIG` with `configs/dataset/mvimgnet_sginput.gin` or `configs/dataset/mvimgnet_sg4x.gin` for the corresponding processed data.
