Question: Voronoi 3D, continued

This is more or less my first try with grasshopper, and it hasn't been easy. The climb has been steep, but the payoff seems quite worth it.I have a ton of issues with this design and hence a ton of…Continue

Voronoi 3D - continued

I’m finally back at this. Hello All, I’ve made a small amount of progress. What I’ve currently got going is a small portion of the overall shape I’m working on. Ultimately this will become a corner…Continue

"Why did you post this on a blog rather than the public forum. Not many people will see it here and I totally missed it until you posted a link from the 'pain points' discussion."

"Grasshopper is an amazing program with some amazing abilities. It has capabilities that conventional apps do not. That’s why despite being extremely proficient in a few other 3D modeling packages, I’ve chosen to dive into Grasshopper.…"

Question: Voronoi 3D

Hello All,I'm new here.So, I've been beating on a problem for several days. I have a developed shape that I'm attempting to apply a 3D voronoi to.I've found examples and tutorials for applying a 2D voronoi to the surface of a developed shape.I've found examples and tutorials for applying a 3D voronoi to a rectangular shape.I've found examples of a 3D voronoi applied to a developed shape.What I haven't been able to find or figure out is how to apply a 3D voronoi to a developed shape.Can anyone here help me out?Thanks~pSee More
