Wavy Pattern on surface?

I am trying to model this wavy effect applied on the attached slab, anyone have some insights about how can it be modelled?

I tried to make it using contour lines but the pattern on slab looks more smooth

this is not only about ornament
check the project site (and keep references…)

Benjamin Dillenburger (ETH Zürich) is a good friend of mine…

kind regards from Zürich.


Wow, thanks for sharing. it’s good to know that. I got that (form and thickness) of the slab affect structural performance but does the pattern affect performance or just for aesthetics purposes and 3d printed formwork exploration?
