 # SpatialTunnel
 
 SpatialTunnel is a Blender-rendered diagnostic dataset for studying how vision-language models represent spatial relations internally. It was introduced in **Why Far Looks Up: Probing Spatial Representation in Vision-Language Models** ([arXiv:2605.30161](https://arxiv.org/abs/2605.30161)).

 | Config | File | Rows | Description |
 |---|---|---|---|
-| `size_variation` | `size_variation.tsv` | 1,100 | Distance questions under controlled object-size variation. |
-| `phase_variation` | `phase_variation.tsv` | 3,072 | Distance questions with controlled angular-position variation. |
-| `contrastive_probing` | `contrastive_probing.tsv` | 1,200 | Balanced spatial-relation questions for contrastive probing. |

 ## Format
 
-All configs are tab-separated files with the same columns:
+All configurations use Parquet files with the following columns:
 
 | Column | Description |
 |---|---|
 | `index` | Row index within the selected config. |
-| `image` | Base64-encoded PNG image. |
+| `image` | PNG image stored as a Hugging Face `Image` feature. |
 | `question` | Spatial question to ask the model. |
 | `answer` | Ground-truth answer for the row. |
 
+`contrastive_probing.tsv` is a TSV file for compatibility with the [contrastive-probing code](https://github.com/cheolhong0916/contrastive-probing).
