## Rendering Scripts

Rendering scripts for generating this dataset are available in the `./rendering` directory. To use these scripts, start by installing the necessary dependencies
```
pip install blenderproc==2.5.0
```

The environmental HDRs used in this dataset are sourced from [Poly Haven](https://polyhaven.com/hdris). You can download all available environmental HDRs using the following command:
```
blenderproc download haven haven_dataset --types hdris
```
Alternatively, you may choose to use your own custom environmental maps.

Modify `GLB_PATH`, `OUTPUT_DIR` and `HDRI_PATH` variables to point to your respective paths, and then run the following commands:
```
GLB_PATH=__YOUR_GLB_PATH__
OUTPUT_DIR=__YOUR_OUTPUT_DIR__
HDRI_PATH=__HDRI_PATH__

# render the normal and material maps
blenderproc run render_normal_orm.py --glb_path ${GLB_PATH} --output_dir ${OUTPUT_DIR}

# render albedo map
blenderproc run render_albedo.py --glb_path ${GLB_PATH} --output_dir ${OUTPUT_DIR}

# render rgb images illuminated by HDR map
blenderproc run render_color.py --glb_path ${GLB_PATH} --hdri_path ${HDRI_PATH} --output_dir ${OUTPUT_DIR}
# render rgb images illuminated by point lights
blenderproc run render_color.py --glb_path ${GLB_PATH} --output_dir ${OUTPUT_DIR}
```
