I have been involved in the development of these softwares:

PoLAR PoLAR (Portable Library for Augmented Reality) is a framework which aims to help creating applications for augmented reality, image visualization and medical imaging. PoLAR is designed to offer useful tools without the need to be a specialist of them. The framework offers the necessary tools to create graphical applications. They are designed to be easy to use and as complete and powerful as possible.

The framework is written in C++ and published under the GNU GPL license. It is written by Pierre-Jean PetitprezErwan Kerrien and Pierre-Frederic VillardPoLAR was funded by an Inria Technology Development Action grant (2014-2016).

Git repository hosted on InriaForge:

git clone


PoLAR gVirtualXRay is a software for simulating X-ray images on the graphics processor unit (GPU) using OpenGL. It includes a framework that combines evolutionary optimisation, soft tissue modelling and ray tracing on GPU to simultaneously compute the respiratory motion and X-ray imaging in real-time.

It has been mainly developed by Franck P. VidalPierre-Frederic Villard helped to develop the respiration application. The source code of gVirtualXRay’s is available under the BSD 3-Clause License. It is partly funded by the European Commission under the Fly4PET project.
