SUMMARY

The discussion focuses on generating a uniform random variable on the surface of a sphere using 1D uniform random variables. The solution involves two unified random variables, Y and teta, which are utilized in the function F(Y, teta) = (Sqrt(r^2-Y^2)*sin(teta), Y, Sqrt(r^2-Y^2)*cos(teta)). This method effectively produces a random variable that uniformly covers the spherical surface.

Lets say we have as much as 1D uniform random variables we want.
How from these 1D uniform random variable, we can create a uniform random variable upon the shell of a sphere?

I have solved the problem.
To get a unified spherical surface random variable you need to do the following:
Given Y and teta are unified random variables each.
The random variable F(Y, teta) = (Sqrt(r^2-Y^2)*sin(teta), Y, Sqrt(r^2-Y^2)*cos(teta))
Gives a unified sphere surface random variable.
