# Theory of Space： Visual Scene Dataset |
|
|
|
|
|
This dataset provides pre-rendered 3D multi-room environments for evaluating spatial reasoning in Vision Language Models (VLMs). It is designed to support the **Theory of Space (ToS)** benchmark, which tests whether foundation models can actively construct spatial beliefs through exploration. |
|
|
|
|
|
**Paper**: Theory of Space: Can foundation models construct spatial beliefs through active perception? |

## Usage |
|
|
|
|
|
Download via Hugging Face CLI: |
|
|
|
|
|
```bash |
|
|
huggingface-cli download MLL-Lab/tos-data --repo-type dataset --local-dir room_data |
|
|
``` |
|
|
|
|
|
Or use the ToS setup script which downloads automatically: |
|
|
|
|
|
```bash |
|
|
git clone https://github.com/williamzhangNU/Theory-of-Space.git |
|
|
cd Theory-of-Space |
|
|
source setup.sh |
|
|
``` |
|
|
|
|
|
