# Omni3D-Bench
This repository contains the Omni3D-Bench dataset introduced in the paper [Visual Agentic AI for Spatial Reasoning with a Dynamic API](https://huggingface.co/papers/2502.06787) Omni3D-Bench contains 500 challenging (image, question, answer) tuples of diverse, real-world scenes sourced from [Omni3D](https://github.com/facebookresearch/omni3d) for complex 3D spatial reasoning.

View samples from the dataset [here](https://glab-caltech.github.io/vadar/omni3d-bench.html).

The dataset is released under the [Creative Commons Non-Commercial](https://creativecommons.org/licenses/by-nc/4.0/deed.en) license. 

## Usage

The benchmark can be accessed with the following code:

```
from datasets import load_dataset
dataset = load_dataset("dmarsili/Omni3D-Bench")
```

We additionally provide a `.zip` file including all the images and annotations.

## Annotations

Samples in Omni3D-Bench consist of images, questions, and ground-truth answers. Samples can be loaded as python dictonaries in the following format:

```
<!-- annotations.json -->
{
    "questions": [
        {
            "image_index"               : str, image ID
            "question_index"            : str, question ID
            "image"                     : PIL Image, image for query
            "question"                  : str, query
            "answer_type"               : str, expected answer type - {int, float, str}
            "answer"                    : str|int|float, ground truth response to the query
        },
        {
            ...
        },
        ...
    ]
}
```
