I am sorry, but I don't understand what you mean. "total_values" is just the absolute number of point pairs generated. Are you referring to the range of x,y,z values generated for points? If so, I still don't understand what you mean with phis and thetas.

In summary, random points are created as follows. For a given length r (separation between the two points):

1. Create a random point inside the volume (or subvolume if running in parallel).
2. Make a random angle (theta, phi), go out r in that direction to find the second point. 

What is it you want to do?
