help me please in expanding cylinder to surface.
I mean, I have cylinder:
x = 3Cos(u)
y = v
z = 3Sin(u)

I guess now I need to find some functions instead of
3Cos(u), v, 3Sin(u)
that will a point on surface (not 3d space), something like this.

PS: the example of my task is a globe transformed to a surface as map.

Appreciate your help, Alexandr.
