GRASSHOPPER VORONOI SKELETON

 
This definition creates a smooth mesh skeleton of a 3D Voronoi.

LOGIC
1. Create 3D Voronoi
2. Remove exterior faces
3. Move Voronoi cells away from each other
4. Loft together common faces
5. Create mesh and smooth connections

GH Version
0.8.0066
Download Grasshopper
Plug-ins Required
1. Weaver Bird
Download Weaverbird 
2. Mesh Analysis and Utility


Tip
In the section "move voronoi cells away from each other" try replacing the volume component
inputted into B of Vec2Pt with a referenced point from rhino for different overall skeleton shapes.

    Thanks for this wonderful project.
    There is one question, near the initial box, how can the box connect twice with the Volume in the section "romove voronoi exterior"?

    Thanks for this incredible insight! ... I am having some trouble in the part where you sort the poly lines, the "area" box gives me an error saying the poly-lines are not closed. I have repeated the process various times, and I haven't been able to find out what I am doing wrong. I got around it by adding the "connect" box between the "plines" and "area" to make sure the rest of the script was fine, and it works but the result is quite different. I would appreciate some help.
    Thank you!

      hi Freesia, i think now your plines is open therefore "area" doesn't work, simply change "с" value on "true" in the plines node.

    Hi,
    I got huge problems with creating the smae object like u. I'm new in GH but i try a lot to understand it, and i think that making complicated objects is best way to learn it. I got problems with loft : "Error : Data conversion failed from Curve to Loft Options" i dont know what i did wrong. I did the same like in replies to Freesia Torres how to make good polylines, but its still not working. Can u help ?

    I'm having problems with the "create cell outlines" step. It keeps saying that I have insufficient points for a polyline" Not quite sure what to do... stuck! Please help!

    Really a great tutorial. But one of those that does not work.

    Good tutorial but seems to get one mistake. The lower connection out of the initial box might in fact connect to a component further to the left of the Volume and that it is an optical illusion that the wire appears to connect to the G and exit from the V. Any idea to solve this ?

    Set the Scale Factor in "Remove Voronoi Exterior" to 9 and it will works.
