algorithmic modeling for Rhino

parametric architecture competition script needed (the swarm and the hive mind)

hi all.

we are a research based design build firm looking to build on some recent successes and wish to submit an entry to the "speculative proposal" portion of the Tex Fab Applied Research competition due at the end of march. i am hoping to see if i can do this as a sort of "HIVE MIND" experiment with one or two or more posters to the forum. i have uploaded two files to http://www.formpig.com/nine_bar-FAR and I have the following goals:

1. To "kinematically iterate" various formal building envelopes based upon a 50' x 100' lot that "conform" to the nine bar linkage geometry.

2. This lot would have "setbacks" consisting of two 5' side setbacks, a 10' rear yard setback and a 25' front yard setback. max height on the structure is 32' and the allowable overhangs into the setbacks are 2'. I would like to find a way to use the "nine bar geometry" to construct a series of iterations for "floors", "walls" and "ceilings", which would then be tied to a volumetric (cubic volume), or a total square footage (perhaps based upon two horizontal section cuts) which was based upon a given number that I will provide per local building code.

3. Laid on top of this we would also have "mcmansion ordinance" requirements based upon the pdf enclosed. i expect to have this "tent restriction" data in digital form to upload to ftp shortly.

It would be up to you individually or collectively to determine how best to position this "in the real world" based upon the lot, setbacks, zoning requirements etc. For instance, perhaps the nine bar configuration has its vertices coplanar with the 50' x 100' x 32' envelope restrictions and then the chosen volume is "trimmed' by the setback requirements. Or perhaps the nine-bar configuration is generated completely within the setbacks, or perhaps it is generated 2' outside of the setbacks so as to take advantage of the 2' overhang allowance on the setbacks, etc.

Given an opportunity to develop the work in a second phase we would have an opportunity to tie this into various efficiencies such as Bill of Materials (wall floor and ceiling square foot calculations), envelope to volume calculations, solar panel efficiencies (solar orientation and envelope geometry) etc, etc (love to get suggestions for this).

I've become /really/ convinced that this would be a /really/ interesting entry based upon my just finishing up Kas Oosterhuis' Towards a New Kind of Building: A Designer's Guide for Non-Standard Architecture". In an ideal world I was hoping that it would be possible to hash this out discussion-wise and then literally passing it around on the list after someone eventually made the first move by tossing out a rough ghx script. My expectation would be to finalize it rapidly in the next two weeks. Something of a contemporary version of a design charette.

However, I realize this may not be workable so if you have experience in this arena and particularly if you think this is a brief that is straighforward enough to be almost literally implemented in Grasshopper, please contact me for any wage and/or contract fee requirements.

I'm getting a bit of a late jump on this but my hope is that with the right participant(s) that I can thrash it together quick enough for the first round.

Got a 404 Not Found for your link (http://www.formpig.com/nine_bar-FAR).

darn it. sorry. http://www.formpig.com/nine_bar_FAR just tried it in Firefox and Safari.

you can just d/l the zip file but i included a folder with the two files as well.

hope it peaks you interest...

i'm sort of stoked to see if it can be pulled off and obviously there are other aspects I have thought through to some extent in terms of actual constructibility...

hi all.

i see this needs some clarification.

i uploaded the envelope as a 3dm file to the ftp above(you can now ignore the pdf).

the goal is to find an /envelope/ that can be kinematically generated in a manner similar to the two images of a "NINE BAR CONFIGURATION" in the images below. eventually one would tie the iterations of the envelope to some metric (for instance some volume or 2300 square feet for two plan section cuts).

anyone smart enough to help me get the two middle illustrations as an "armature" into the CAD in order to start talking about scripting something? RhinoWorks can accomplish kinematic animations/rotations but my feeling is that I need GH in order to import/export some metrics to make it more intelligent (Rhinoworks plugin: http://drivingdimensions.com/Rhino/store/).

Thanks, Jon
