gyoto-bin 1.4.4-3 (amd64 binary) in ubuntu focal

 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 package contains the `gyoto' command-line utility. More complex
 uses of the Gyoto framework can be achieved using the python3-gyoto
 or yorick-gyoto packages. Gyoto can be extended with plug-ins (see
 libgyoto8-dev).
 .
 MPI parallelization requires the mpi-default-bin package. Producing
 videos requires the python3-gyoto and python3-opencv packages.
