Authors#

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

Use case#

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

Licenses#

The core of the photon mapping engine is released under the MIT License by YumcyaWiz.

The rest of the project is released under the CeCILL-C free software license agreement.
