# Synthetic Data for Evaluation
[![Blender](https://img.shields.io/badge/blender-%23F5792A.svg?style=for-the-badge&logo=blender&logoColor=white)](https://www.blender.org/)

This repo includes the synthetic data used in our paper: [Reflect3r](https://arxiv.org/abs/2509.20607v1). 

We built a collection of synthetic Blender scenes containing mirror reflections to evaluate single-view stereo reconstruction in the context of mirror. 

Download our synthetic evaluation data [here](https://huggingface.co/datasets/jinggogogo/reflect3r_synthetic_data). 
- Download the [original blender scenes](https://huggingface.co/datasets/jinggogogo/reflect3r_synthetic_data/tree/main/blender_source_files)
- Download the [processed data](https://huggingface.co/datasets/jinggogogo/reflect3r_synthetic_data/tree/main/rendered_data)

Scripts for Modelling in Blender
- Use [this python script](https://github.com/jingwu2121/reflect3r/blob/main/data_toolkit/add_mirrored_cam.py) to model a mirrored camera against the mirror plane in Blender's scripting tab. 
- Use [this python script](https://github.com/jingwu2121/reflect3r/blob/main/data_toolkit/render_depth.py) to render the depth, rgb images and camera information from Blender scripting. 

Generate the ground-truth point cloud for evaluation using [this script](https://github.com/jingwu2121/reflect3r/blob/main/data_toolkit/syn_gt_point_cloud_gen.py):
```bash
python syn_gt_point_cloud_gen.py --scene_name '<SCENE TO PROCESS>' --save_root '/path/to/save'
```

The 16 Blender scenes are collected from online websites, we rearranged and cleaned the scenes and modelled a mirror on top of them for research purpose. Here we listed all the original download links for these scenes, we thank these designers for their great work.
