Environment Map without gradients as illustrator curves

Is there a way to make a script that works like sphere map/environment map but creates curves instead of textures? I’ve been trying this for years now with no luck.

I even tried paying for the script on Fiver with no luck

Basically im trying to make a cell shaded look for vector curves in illustrator. You wouldn’t think it would be so hard but I’m just not good enough it seems

Hello
I don’t know if I am alone, but I don’t understand. From some research you seem to want toons,


Have you some examples that could illustrate what you want?

That toon shading is exactly what im looking for. Obviously the color would be applied as hatches after Make 2D. But the curves should be where the color transition happens.
