Hello,

I'm trying to find some examples on this question, but so far without any success.

I'd like to represent a surface when I have its cartesian equation, let's say for example :

4 = x² + y² + 2*atan(z) when (x ; y ; z) are between -3 and +3

I tried to use many sequence nodes, but so far couldn't figure out how to represent the full surface with variations in all directions to get something close to picture below :

I can represent some curves, but never full surface.

Does anyone have some hints for me please ?

Thank you!
