edit 29/04/14 - Here is a new collection of more than 80 example files, organized by category:
KangarooExamples.zip
This zip is the most up to date collection of examples at the moment, and collects t
ers and researchers, programmers and artists, professionals and academics who come together for 4 days of intense collaboration, development, and design.
The sg2012 Workshop will be organised around Clusters. Clusters are hubs of expertise. They comprise of people, knowledge, tools, materials and machines. The Clusters provide a focus for workshop participants working together within a common framework.
Clusters provide a forum for the exchange of ideas, processes and techniques and act as a catalyst for design resolution. The Workshop is made up of ten Clusters that respond in diverse ways to the sg2012 Challenge Material Intensities.
Applicants to the sg2012 Workshop will select their preferred cluster from the following:
Beyond Mechanics
Micro Synergetics
Composite Territories
Ceramics 2.0
Material Conflicts
Transgranular Perspiration
Reactive Acoustic Environments
Form Follows Flow
Bioresponsive Building Envelopes
Gridshell Digital Tectonics
More information about the Workshop and Clusters can be found here:

The application process will close on January 15th, 2012.
Full Fee $1500
Reduced Fee $750
Scholarship Fee $350
Fees include attendance to both the workshop and conference from March 19th-24th.
Reduced Fee and Scholarships are available only for Academics, Students and Young Practitioners, and are awarded during a competitive peer review process.
sg2012 takes place from 19-24 March 2012 at EMPAC (http://empac.rpi.edu/) and is hosted by Rensselaer Polytechnic Institute in Troy, upstate New York USA. The Workshop and Conference will be a gathering of the global community of innovators and pioneers in the fields of architecture, design and engineering.
The event will be in two parts: a four day Workshop 19-22 March, and a public conference beginning with Talkshop 23 March, followed by a Symposium 24 March. The event follows the format of the highly successful preceding events sg2010 Barcelona and sg2011 Copenhagen.
sg2012 Challenge Material Intensities
Simulation, Energy, Environment
Imagine the design space of architecture was no longer at the scale of rooms, walls and atria, but that of cells, grains and vapour droplets. Rather than the flow of people, services, or construction schedules, the focus becomes the flow of light, vapour, molecular vibrations and growth schedules: design from the inside out.
The sg2012 challenge, Material Intensities, is intended to dissolve our notion of the built environment as inert constructions enclosing physically sealed spaces. Spaces and boundaries are abundant with vibration, fluctuating intensities, shifting gradients and flows. The materials that define them are in a continual state of becoming: a dance of energy and information. Material potential is defined by multiple properties: acoustical, chemical, electrical, environmental, magnetic, manufacturing, mechanical, optical, radiological, sensorial, and thermal. The challenge for sg2012 Material Intensities is to consider material economy when creating environments, micro-climates and contexts congenial for social interaction, activities and organisation. This challenge calls for design innovation and dialogue between disciplines and responsibilities. sg2010 Working Prototypes strove to emancipate digital design from the hard drive by moving from the virtual to the actual in wrestling with the tangible world of physical fabrication. sg2011 Building the Invisible focused on informing digital design with real world data. sg2012 Material Intensities strives to energise our digital prototypes and infuse them with material behaviour. They have the potential to become rich simulations informed by the material dynamics, chemical composition, energy flows, force fields and environmental conditions that feed back into the design process.

ive 'correct' normal.
Non-normalized cross products is effectively weighting face normals by area, and is fast and simple, so we put that one as the default.
In some cases normalizing the cross-products improves the result, but not always.
Another option is to weight by angles, though this is computationally slightly more expensive, so might not be ideal for real-time updates on large meshes.
As an example, here is a mesh with a 90° corner, and uneven meshing on the 2 sides.
The arrows show:
0- Area weighted (non-normalized cross products)
1- Angle weighted
2- Normalized cross-products
Here the angle-weighted normal is the one at 45°, which is intuitively the 'best' one in this case.
These 3 seem to be the most commonly used, but there are many other possible definitions of normals - such as inverse-area weighted, mean curvature, etc...
I think really what would be best would be to put a few of these into Plankton, and include an optional argument in GetNormal for selecting which one you need for a particular application.
Pull requests welcome if you feel inspired to add this!

us allows Grasshopper authors to stream geometry to the web in real time. It works like a chatroom for parametric geometry, and allows for on-the-fly 3D model mashups in the web browser. Multiple [Grasshopper] authors can stream geometry into a shared 3D environment on the web – a Platypus Session – and multiple viewers can join that session on 3dplatyp.us to interact with the 3D model. Platypus can be used to present parametric 3D models to a remote audience, to quickly collaborate with other Grasshopper users, or both!
You can down load the Grasshopper plugin at food4rhino, and visit 3dplatyp.us to view your geometry on the web. This first round of Alpha testing will run for two weeks, until April 24 2014, after which the Grasshopper components will not solve.
We are very interested in hearing feedback from the community while the project is still in the prototyping stages of development. Please use the comments on this discussion to ask questions, suggest ideas, report bugs, etc. We are planning on rolling out another public alpha release or two this Spring, depending on how this first one goes, in advance of our Technology Symposium and Hackathon in New York.
Check out our getting started video below, and enjoy!

e rod with circular section (no goals allow for controlling torsion for what I know). The rods are set with two options, with straight rest position or the (initial) bent one. The calibration integrated with the model is more about giving a scale between the forces rather than the will to accurately simulate them (at the moment). Anyway, I am trying to do it on a macro scale, instead of a micro, with elements which are rather thin.
The system at the moment is not stable. In fact, besides the rods' characteristics is quite fundamental to keep them planar when they intersect. I am lacking something but also probably missing some parameters. In the script, there are two goals to define this: impose 90° between vertical and horizontal, as well as between these and a normal to their intersection. For my understanding, angle goal works tri-dimensionally without a preferred plane and this (hopefully) should address it.
Just wondering if anyone can give me a hint on this. After this step, it would be great to understand if the system can get out of its plane (through a pull force out of its plane, simulated in the script through point loads in the joints). I am still not entirely sure about the possibility of doing this. By looking at how other auxetic patterns have been used to generate freeform surfaces, I am giving it a try.
Thank you
Claudio
PS: I noticed also this post and this, really interesting. I see the problematic over the stability and the necessity to separate the states with an energetic hill in the first, as well as some potential in using auxetics in the latter.…
opening a simple file with 30 curves being lofted took like 2 minutes to complete and Rhino crashed afterwards saying:"Windows is out of memory and Rhino will close after you click ok."evethough I still had 7GB of free physical memory and my page file is set also to 16 GB just to be shure...I then switched to Rhino 5.0 Version 5 SR14 64-bit (5.14.522.8390, 05/22/2017) which also had big problems to display the lofted surface. It was unresponsive after loading the file for a minute and a half and then it normally displayed the lofted surface. Every move of camera takes at least 10 seconds to update, but at least it runs. GH profiler says the loft took only 12 ms (90%).
So I'm suspected my graphics card, because the Windows are just three weeks from a clean install. I've also updated my Graphics Driver from the stock Windows one to Intel HD one, but nothing changed.Is there something I'm missing??? What can I try next?My specs:CPU: i5-3320M @ 2.60 GHzRAM: 16 GBGPU: Intel HD Graphics 4000, driver: 07.04. 2017, version 10.18.10.4653
