This path-tracer is intended for use in the domain of X-ray astrophysics, specifically for calculation of observables from neutron star emissions. It includes geodesic paths for Schwarzschild spacetime.
For viewable images, the .ppm format is used.
For scientific data, the portable .dat extension is used and
a file management driver (for serializing and deserializing the data)
provided as part of the program.
The binary is developed and built using fpm (the fortran package manager by fortran-lang project).
