Gyoto is a framework for computing geodesics in curved space-times. The gyoto utility program uses this framework to compute images of astronomical objects in the vicinity of compact objects (e.g. black-holes). Such images are distorted by strong gravitational lensing. The gyoto program takes a scenery description in XML format, computes this scenery using relativistic ray-tracing, and saves the result in FITS format.

This metapackage depends on all the Gyoto interfaces (command-line, Python 3 and Yorick).

MPI parallelization requires the mpi-default-bin package. The Gyoto documentation is provided in the gyoto-doc package.
