Hi,

I'm trying to understand toroidal coordinates, that are a 3D version of bipolar coordinates. Well, I don't understand any of them, already cheked wiki and wolfram sites, but they don't give any clear explanation (in my opinion).

Is there a way to get an intuition for obtaining the cartesian coordinates x,y,z in terms of bipolar and toroidal coordinates?
