The public release is organized into three subsets:

- `count`
- `detect`
- `mcq`

## Directory Structure

```text
view2space-v1-release/
  README.md
  count/
    overall.jsonl
  detect/
    overall.jsonl
  mcq/
    overall.jsonl
  images/
    img_000001.png
    img_000002.png
    ...
```

Each subset contains one `overall.jsonl` file. Each line is one question.

## Data Format

Each JSONL record contains the following public fields:

- `q_idx`: question id, such as `mcq_000001`
- `q_type`: question family, one of `mcq`, `detect`, or `count`
- `question`: question text
- `options`: multiple-choice options for MCQ questions; empty for non-MCQ questions
- `question_prompt`: extra prompt text when applicable
- `answer`: ground-truth answer
- `image_paths`: relative paths to the images used by the question
- `supporting.draw_boxes`: optional input boxes associated with one or more images

Notes:

- `image_paths` are relative to the dataset root, not to the subset folder.
- Example image path: `images/img_000123.png`
- `q_type` uses only the public family labels `mcq`, `detect`, and `count`.

## Example Record

```json
{
  "q_idx": "mcq_000001",
  "q_type": "mcq",
  "question": "All views are captured from the same static scene arrangement, but from different positions and angles.\nIn view 2, consider the nearest 'man with an orange hat, crouching'. Where is the 'white temple' relative to this 'man with an orange hat, crouching'?",
  "options": {
    "A": "left",
    "B": "right",
    "C": "front",
    "D": "back"
  },
  "question_prompt": "",
  "answer": "C",
  "image_paths": [
    "images/img_000813.png",
    "images/img_000806.png",
    "images/img_000815.png"
  ],
  "supporting": {
    "draw_boxes": null
  }
}
```

## Basic Usage

```python
import json
from pathlib import Path

dataset_root = Path("/path/to/view2space-v1-release")
jsonl_path = dataset_root / "mcq" / "overall.jsonl"

with jsonl_path.open("r", encoding="utf-8") as f:
    first = json.loads(next(f))

image_files = [dataset_root / rel_path for rel_path in first["image_paths"]]
print(first["q_idx"])
print(first["q_type"])
print(image_files)
```
