In pursuit of developing my own planetary software the first thing I needed to know was how to draw a sphere modelling the sky and how to project the stars on it.
Drawing spheres is simply when using spherical coordinates instead of the cartesian ones.

One radian is the angle of an arc created by wrapping the radius of a circle around its circumference.
1 radian is equal to ~57,2958 degrees.
Converting from radians to degrees (and vice versa) is pretty straight forward and it can be done using this two formulas.
