What is the equation of warped disk in Cartesian or Spherical coordinate system?

My teacher gave us the assignment to find the moment of inertia of any shape you want. So I decided to find the moment of inertia of our milky way galaxy.

I found out that our galaxy is shaped like a warped disk, not a flat. After I knew about that, I looked for the equation of the Milky Way's shape. But, to me, Nasa's and some high university papers had so many big wards that I could bearly understand what they were talking about(I'm Korean.. ^^). I'm sure that I can understand the equation if I had it, but I just can't find any information about them.

I would really appreciate it if someone could tell me what you know about these equations (shape).

Thank you!
