How would I generate a Voronoi pattern with smooth edges?

Hi all, I am trying to create an organic porous shell structure in grasshopper. I have made a volume already, and I would now like to create a Voronoi pattern with smooth edges in the cells to look something like this image:

With the final model looking something like this:

I have been using Intralattice and Weaverbird, but these fill in a volume with a lattice, rather than creating a 2D pattern that could then be “draped” over the volume I created.

Any suggestions for a direction to head in? (11.8 KB)
