The new generation of gamma-ray telescopes has revealed a richsky at very high photon energies. The unveiling of the nature of these sourcesand the understanding of the physical processes that give rise to the gammarayemission are among the most important present challenges of high-energyastrophysics. To investigate these issues, the propagation and interaction of theemitted electromagnetic radiation, both within the source and during its journeyto the observer, must be understood. In this work we describe the development ofa tool to provide an accurate, ab-initio description of the propagation of gammarays in astrophysical environments. We expect this tool to contribute to theunderstanding of the physics of cosmic gamma-ray emitters.
