3D Voronoi "Porn" in Grasshopper

There has been an interesting discussion going on over at the Grasshopper Google Group for achieving 3D Voronoi within the Grasshopper environment.

Visose recently posted a method for using the VB.NET script component in conjunction with the Pointset Reconstruction plug-in in order produce a set of 3D Voronoi polysurfaces (BReps) within Grasshopper.
The method does not allow for auto-updating. You will have to hit F5 in GH to refresh the result. Still, this is pretty effective if you want slightly more automation than is currently offered by the PSet plug-in.

I have posted the *.ghx file of the method: GH_3D Voronoi_Pointset Macro Method.ghx

You will need to have the Pointset Reconstruction Plug-In installed for this to work. The image above is a result I got after modifying the voronoi BReps within Grasshopper (offset and fillet of 3D voronoi = trendy architecture!)

Ribbing Revisited

I have received several requests to post the Grasshopper definition for rib system screen shot I posted here.

I did not post it before because the definition was extremely unorganized and very "touchy".

I have since rebuilt the definition to be compatible with GH v.0.6. Also, the definition no longer relies on solid booleans to create the rib notches (I have found solid booleans to be extremely unreliable in Grasshopper).

Anyway... now available by popular demand:

Note: I make no guarantees for how well the definition works. Sometimes it has problems when a vertical rib intersects a surface seam... Suggestions welcome!

UNL Grasshopper Workshop Results!

On Saturday April 11, I instructed a 1-Day (9AM-5PM) Grasshopper workshop at UNL College of Architecture for undergraduate and graduate students. There were 25 students who participated. Most were familiar with Rhino but had never used Grasshopper before. I covered a lot of topics for one day and the students did an excellent job adapting to a new way of working and designing. Below is a summary of what we accomplished...

PS... a new version of the plug-in was released this past Friday: click here

I began the day discussing the interface and how Grasshopper manages data using lists... this included an overview of the new functionality offered by trees and paths...Next I did some step-by-step exercises showing how to set up some basic relationships between geometry.Following this, we moved into more complex design problems including a bridge system and a tower study. As students become more comfortable with grasshopper they began to move into creating their own design problems and studies.

Below are some examples of what the students produced...

GREAT JOB GUYS! I hope to be back in NE for another one in the future!
