**sphere_stereograph_test**,
a C program which
calls sphere_stereograph() to
implement the standard stereographic mapping between the unit sphere and
the plane Z=1, as well as a generalization of this mapping.

sphere_stereograph, a C library which computes the stereographic mapping between points on the surface of the unit sphere in 3D and points on the plane Z = 1; a generalized mapping is also available.

- sphere_stereograph_test.c, a sample calling program.
- sphere_stereograph_test.sh, runs all the tests.
- sphere_stereograph_test.txt, the output file.
