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. 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}
