Computational Design Meme Contest

The Proving Ground is holding a computational design meme contest that will be judged in the most unscientific way possible.  The 'top 4' will be arbitrarily posted to The Proving Ground blog and the full gallery of submissions will be available on Facebook.  

Winner gets a pat on the back... maybe a free beer if we somehow cross paths in the future.

Send memes to:  …

Slingshot! Database Documentation and Tutorials

Slingshot! users,

I have started to create some better documentation and tutorials for the Slingshot! plug-in. The page is a work-in-progress.  More examples and reference materials will be made available as time permits.

Currently, there is documentation for:

  • Installation
  • Component list
  • Basics: Connections, Commands, Queries
  • Creating a Mesh Database
  • Creating a Genome…

Energy Modeling with Grasshopper (Proof-of-Concept)

Grasshopper users have all kinds of simulation tools at their disposal... however, I have yet to see an attempt at integrating energy simulation tools with Grasshopper... so here is a 'weekend warrior' study which links Grasshopper to EnergyPlus.

Genome Database, Slingshot! + Galapagos

I have been playing with recording the slider activity and fitness values as Galapagos runs a solution.  The parameter changes are recorded using the 'record' component and then sent to a MySQL table.  


It is then possible to query the database and easily investigate the entire range of solutions offered by the evolutionary solver.


For example, I can search for all genomes with a fitness > x... or all genomes with a gene = y.  Or I can display multiple…

Grasshopper > AutoCAD Open Source Plug-In

I have released an open source plug-in which allows Grasshopper to send commands directly to AutoCAD using COM.  I have tested this on my machine running AutoCAD 2011 64-bit on Windows 7.  


I have released the source code so hopefully the bones can be used for different purposes and software versions.


If you develop a cool use for this, let me know!  I would love to feature it.




The plug-in and source code are available at…

Slingshot! GH+MySQL Plug-In v0.6 released for testing... Group created...

The MySQL plug-in allows you to access, query, and write data to MySQL database servers with Grasshopper.  SQL stands for "structured query language" and allows you to set up sophisticated relationships between large sets of data.


I have been experimenting with using MySQL as a data store for shared parameters and other information that multiple instances of Grasshopper (or other software) can access and use.


Feel free to give it a try and provide…
