Curve growth - differential growth (Where to Start?)

[laurent_delrieu]

Hello
a first good thing is to search ! There are plenty of definitions on curves growth …

Create such a this pattern in grasshopper

So, I am trying to implement the ‘growth’ of a few concentric curves, as suggested by this Zaha Hadid work. One thing I am not understanding is how Kangaroo handles multiple curves in a tree structure. For example, say I have 4 concentric rectangles, as in the attached script, modified after Riccardo’s links to ‘folding curve on a surface’. Despite various attempts at a tree structure, the curves output are flattened, so I lose the distinction between the curves. An approach which might work,…
