generative modeling for Rhino
I created a 3D voronoi block from a point cloud and am now trying to figure out how to create the script to turn the voronois into a skeleton like the picture below. I realize the script must be somewhere in one of these discussion forums, but I've had no luck with finding it yet. Any help would be appreciated. Thanks.

Here is an easy way to do this (no script needed)
Extract the edges from the cells and bake them to make them curves, then delete all duplicate edges.
then watch this video
easy as pie!
Okay... T-Splines is nice but not actually free :D ...that is if you are not a student and have access to students.autodesk.com
The constuction of the example is pretty simple actually.
- explode all cells
- extract the edges of the faces (+ join them)
- extract the vertices of the edges
- feed the vertices as control points to closed, periodic NURBS curve.
- loft from face edges to NURBS-Version (you might need to adjust the seams between polyline and NURBS curve in some cases.)
And the picture came from:

It's the source!
BTW did you see this project?
The fluidity reminded me of your P-Wall casts, but some of the folds in that concrete are wicked.
Yeah, a friend showed that to me a couple weeks ago. Pretty amazing. I'd love to see the formwork for it. My worry is that there is a huge amount of CNC milled foam lurking behind this project.
Yeah, probably very sacrificial foam...
You're someone who will probably know answer to my question :)
If I would mill the foam (XPS aka styrodur (polish market)) what I need to apply on milled surface to use it as formwork ?
Another one : I use universal putty for milled xps finishing (this time used as model, not formwork), do you know something better than putty ? Better = easier/faster to finish
I actually don't know too much about casting concrete against foam. The P_Wall projects that I have done I have cast plaster against fabric and it worked great. I have also cast concrete against silicone rubber and that is very good finish but the silicone is expensive. I have also know some people here (Kreysler & Associates) who mill cheap EPS foam 1cm BELOW the final surface, put 2cm of plaster on the milled foam, and then remill the plaster back down to the final surface. This gives a very high resolution plaster surface that can be used to cast fiberglass against. I imagine the same would work for concrete but you might want to wax the plaster surface first.
is there a possibility to know
more about this project?
love it! please reply. :-)
