Heatherwick Vessel// ellipse geometry stairs

Hi It is first topic I open in this forum so my apologize for all the mistakes I will do, btw I would like to model something like the Heatherwick’s vessel and to apply it to any kind of curve surface, like an ellipse or a not regular curve, is there a way to parametrize the heatherwick pattern?
best regards

For sure there are some ways, read this post, you could begin with this.

And some reference of this beautiful project

Thanks Laurent for the fast answer, I have already read and analyzed ur code in that post, it is amazing but going through the equations I did not figure out how to adapt the geometry, basicaly I have my “city” pretty unregular (as u can see below)

and I would like tocreate that kind of stairs’ skin on it

Have you given it a try? Post some definition.

For sure, like @Michael_Pryor said, a definition will help. But you also have to find some logic.
Does the landing are shifted ? from the stairs. As all heights are the same you will have the same number of steps. Do you want to lengthen each steps … to have more stairs … Parametric model means you have parameters but also models. Welcome to parametric world.

I don’t think it is easy to create this design and than apply it to any curve, the global shape maybe but the stairs need alot of wotk

Sorry for the delay I had no opportunity to work on it in the last days, now I am on it again , I am attaching the definition below, I have almost solved the problem, there is a last thing I can not figure out, I need to create the platform from the converging points and to have just two lines (stairs) going up and two going down from each platform.
