## 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} |
|
``` |
