minimal but extensible header only implementation of photon mapping in C++.

create and activate the conda environment:

conda env create -f environment.yml
conda activate photonmap

To install as a Python library:

python -m pip install ./

To compile the source code without installing (useful for debugging):

mkdir ./build && cd ./build
cmake -DCMAKE_BUILD_TYPE=Debug ../
make -j

conda activate photonmap
cd examples/python/plantgl-rad-scene
python planglRadScene.py

• The result of the simulation is in the folder: ./results/
• Tools to evalutate result: .examples/python/Evaluation Simulation SEC2/

    conda activate photonmap
    pip install pgljupyter

    cd examples/python/plantgl-rad-scene
    jupyter notebook

This project was originaly developed by YumcyaWiz(Kenta Eto). Main extension were developed by Aurélien Besnier and Nguyen Tuan Minh with contribution of J. Bertheloot, F. Boudon, E. Faure. This work was funded by INRAe Metaprogramme DIGIT-BIO (Digital biology to explore and predict living organisms in their environment).

This project is used in the coupling of MorphoNet and L-Py for the project Physioscope.
