Hi all,

I wonder if there is a way to generate hierarchical patterns like leaf vines as attached.  
I try the 2D voronoi component in grasshopper but seems the pattern it generates is quite random and it is not possible to control the “vine” structure…  
Does anyone know how to generate a pattern like leaf vine? Are I wrong to use the 2D voronoi component?

Leaf venation patterns are not voronoi based, the voronoi like result should emerge from the venation algorithm, because if you maximise the distribution of nutrients in a vascular system and minimise the material and distribution cost in a finite, flat region like a leaf, the result tends to a voronoi diagram, as it optimises the position of the veins in relation to the area they nourish. Here is the paper you need:
