ts in extreme aliasing effects that carry into the 3D realm as regular steps along what should be smooth surfaces.
On sleeping on it, I realized I hadn't yet tried fast Unary Force on fine quad meshes from the standard Grasshopper meshing system that includes the meshing options component.
Bingo! It's fast now. Workable. I don't need super fine meshing since I'm not running from aliasing. I can still use rather fine local meshes since Unary Force lets Kangaroo do a simple thing just in the Z direction rather than a full 3D force.
After only a minute or so of Kangaroo initialization that slows the interface, each of a dozen needed cycles takes half a second, FOR THE ENTIRE GRAPHIC.
I just set the timer to 1 second so I can move around the interface, and I double click the Windows taskbar timer shut-off to enjoy the result.
WHILE RUNNING VIA TIMER, IF I CHANGE A SPRING/FORCE SETTING IT SUFFERS NO DELAY AT ALL AND JUST ALTERS THE OUTPUT OVER TIME. I can change Unary Force from 20 to 100 and immediately see the bigger areas balloon like crazy:
It's fast enough overall to play with, yet the individual steps are slow enough that it's fun to watch the hysteresis as it overshoots back from 100 to 20 Unary Force, going concave in the middle of bulges then back to more shallow hills.
A force of 1000 is a bit disturbing, I wonder if I can tamp it down with greater spring strength or will that just give me the same result as before?
Looks like it's the same, just the ratio matters. Makes sense I guess. At one point it blew up though. Hitting the reset button...a minute later it blows up again...and just doesn't like huge numbers, so I don't see an advantage playing with bombs. The high mesh strength is pulling the mesh apart.
With low Unary Force and moderate mesh tension, you get flat tops, as if the overall force on the mesh fighting its anchored edge vertices, is enough to displace it, but the surface itself is too stiff to care about local gravity.
Then you have less flat areas as you increase Unary Force:
Weird, there *is* some sort of absolute effects, rather than just relative, between Unary Force and spring stiffness, since now I'm getting flat tops even in the extreme:
Oh, wait, strike that, I may be seeing but a single step with the timer off, subject to hysteresis. With the timer back on...it can sit there a minute...not locked up but just idling...until you see the Display > Widgets > Profiler time start cycling to near half minute numbers...makes you want to hit the reset button...and indeed that locks the interface for another initialization...and yes, it was merely hysteresis, not an equilibrium result. My former flat tops may have been due to that too, due to my use of the Windows taskbar timer disabler. The lesson is that you can obtain different results by using a long timer setting and just stopping it before it equilibrates.
This script is a keeper, fast and fun after the relatively mild Kangaroo initialization period is over.
The uniform mostly quad meshing is all done in Grasshopper too, from any flat surface with holes, especially from images of shapes that are traced with potrace to give surfaces with holes.
Could I switch to hex meshes from triangular meshes to do the same thing with fewer vertices?
Are there other forces I can add to smooth the bulging? Letting things bulge is not so bad if you then just scale down the result in Z afterwards (though perhaps the same result could be had with lesser force):
Also, can this same thing be done with possibly faster Kangaroo 2?…

○ Fixed a bug with the Convex Hull algorithm (while inebriated on Tokaj no less).
Important notes:
The zero-length-slider-ultra-crash may or may not still happen. I've fixed a bug in slider code that may or may not explain why it happened to begin with (though probably it doesn't) and also some safety code. Please let me know if this is still a problem.
All the Set components operate on simple data types only (Booleans, Integers, Numbers, Complex Numbers, Strings, Intervals, Vectors & Points). They will not work correctly on more complex types such as Curves, Meshes or Breps. I do not know if they ever will.
I've tried making the sliders and tumblers (the controls, not the canvas objects) easier to use. Basically it should now be obvious based on the display whether a slider or tumbler has focus. Slider have a dotted rectangle drawn in them when focused, tumblers are drawn as 3D objects instead of flat objects). When a slider or tumbler has focus, just typing should automatically bring up the text input override. Please test that this works as advertised and is not 'weird'.
Note to GHA developers: The Internal_Icon_24x24 property on Components and Custom object is now Obsolete. It still exists for the time being, but you are advised to use the Icon property instead.

The Responsive Surfaces Workshop _ LA 2012 will explore the use of Grasshopper, Firefly and Arduino as creative and technical tools in the design, simulation and prototyping of intelligent building skins. Grasshopper, a free plug-in for McNeel’s Rhino modeler, allows designers to create adjustable parametric forms through graphic icons rather than programming. Firefly is a new set of comprehensive software tools dedicated to bridging the gap between Grasshopper, theArduino micro-controller, the internet and beyond. It allows near real-time data flow between the 3D digital and physical worlds, and will read/write data to/from internet feeds, remote sensors, connect with machine vision protocols, and more.
Instructor: Jason Kelly Johnson, Firefly co-developer, Future Cities Lab and the CCA San Francisco Lecturer: Miles Kemp, President of Variate Labs and co-author of “Interactive Architecture”
Additional Information: Workshop Location: 8451 Beverly Boulevard, Los Angeles, CA 90048 (GOOGLE MAP) Required Materials: Each participant should bring their own Sparkfun Inventors Kit or equivalent. Software: Please have the following software installed on your personal laptop computer - Rhino (SR9) + the latest versions of Grasshopper, Firefly and Arduino.

ngoing Co-de-iT research called “inFORMed matter“.
The “inFORMed matter” research project focuses on the exploration of additive fabrication processes, aiming to inform as in to produce form through the morphogenetic properties and capacities of matter by embedding further information structures during the fabrication process itself.
The goal is to go beyond the current state of prototyping, according to which the physical prototype should be as close as possible a clone of its digital counterpart, thus making fabrication a purely replicational phase. Instead, by coding and embedding additional levels of information aimed at mapping and defining material features and behaviors as well as different deployment patterns from which physical and aesthetic properties arise, the production and digital fabrication phase becomes an integral part of the design process.
The workshop it’s focused about the exploration and development of the whole process of design and digital manufacturing through additive processes of ceramic mixture materials.
[.] Workshop topics:
- Anticipate material behavior through digital simulation: test and apply different tool-based conditions and parameters (extrusion direction angle, speed of extrusion, variable layer thickness, etc … ) and evaluate the consequent material behavior in order to get useful feedback for the next iteration of the digital model. The aim is to understand how to embed material properties as code/information during the digital design phase, fine tuning it towards the desired effect-outcome. - Seamless design-to-machine pipeline: shorten the information pipeline from the design process to the constructor machine. This is achieved by acting on both factors: informing directly the machines by generating the necessary code in the design tool and build the design process around the capacities of the machines involved. - Embed morphogenetic material properties as design factors: understand and manage such properties, behaviors and their potential morphological outcomes for different materials, from clay to biologic matter, in order to map and use them as an atlas of expressive possibilities and performances of the material. - Understand constraints and opportunities determined by the chosen constructor agent/machine: learn to use and manage different machines to handle the extrusion tool for additive processes and learn to evaluate and exploit the influence, constraints and given opportunities provided by different machines and movement technologies.
During the workshop will be used as tools for handling the special ceramic extruder, a customized 3D printer, type delta, and a 6-axis Comau Robot NJ 60.
The final output will be then the result of influence, cooperation and conflict of these aspects upon, with and onto one another. Only successfully combining computational simulation, material properties and capacities and machine constraints and opportunities we can effectively evaluate and push further the design process potential and foster design and fabrication skills and sensibilities that will form the basis of a more comprehensive awareness in regard to the relations between computation and material aspects.

racting isocurves in Grasshopper in order to use them as more curves. If I could figure out the thorny use of Grasshopper data trees within Daniel Piker's Geometry Wrapper VB script that is used here, it would be considerably faster than having to include each isocurve in a separate field strength lookup.
The way marching cubes and an isosurface work in the code, is to simply find the distance to the closest point on each curve and run the distance to that point through a slow equation to determine field strength there, usually an r^2 operation, and this causes awful bulging where geometry clusters, so I just hacked it to use no math and instead yes/no values based on a fixed radius value, doubling the speed of the script and removing all bulging effects, so it's not really metaballs any more but after MeshMachine relaxes the mesh under tension, the result is similarly smooth. To build up a full 3D spacial field, it simply adds the field values from each curve (or point) together via a loop over all those geometry objects, so there is no big implicit equation created except such summation.
HOW DO I ADD SURFACE ISOFIELD TO THE SCRIPT ITSELF SO I CAN AVOID THE ISOCURVE KLUDGE?
It's not the VB I'm thrown off by but the lack of a real loop where a data tree is used:
I can likely write my own calculate_surface_field function since it just needs to spit out one of two fixed numbers depending on using Rhinocommon to find the distance of the test point (a corner of a marching cube) to the closest point on the surface. But the above loop doesn't cooperate with my attempt to rewrite it as simple loops going through each point, curve, and surface for each test point. I can barely tell what's looping here, as he has stuffed all geometry into one container and then tests for curves. I'd rather just make loops for separate Points, Curves and Surfaces inputs and get rid of the baffling data tree.
The overall canvas is also rudely updating the preview twice, making it much slower than the two big components actually take so solve, as I believe it may be regenerating a display mesh between VB and MeshMachine solutions?

s continuously growing over eleven months.Have an extra minute or two version: Hello Everyone! I am sorry for the sort of 'spam' message, but I promise this does have something to do with Grasshopper. Next week there will be an opening for an exhibition called 'Fabrication Laboratory: New scenarios in 3D Design and Production.' The ehibition will run for eleven months at the Disseny Hub Barcelona. The curator, Marta Malé-Alemany is bringing together the cutting edge and future of fabrication as we know it. I was fortunate enough to be considered for a piece investigating Collaborative Fabrication. With the support of the Institute for Advanced Architecture of Catalonia (IaaC) and the DHUB, we created something called 'Collaborative Cloud.'Collaborative Cloud is an open project which investigates the potentials of local fabrication and distributed design. The project, by giving anyone the access to contribute in its development, attempts to produce a physical object based on participation which goes beyond the limits of physical proximity. Collaboration is made possible by an interface which allows the participant to design and inform a piece of the cloud. The information generated by international participants will be accessed by the DHUB Fab Lab to fabricate pieces which provoke the growth of the project over eleven months.This is a project created and produced by the Institute for Advanced Architecture of Catalonia, organized by Disseny Hub Bacelona, and designed by myself, Victor Viña, and Areti Markopoulou.So, if I have intrigued some of you, please go to: http://dhubfablab.cat/ccloudand design your piece of the cloud! We need submissions! Next week we open with 200 pieces of the cloud! If you want to make multiple submissions, just change the email address a bit (we will use the first email address submitted in case we contact the participants for special events). There are some known issues we are trying to iron out with the interface. Please reply in this thread if there is an issue. Definitely a JAVA warning will pop up asking if you want to block the applet...say No! If you block it, well, it wont work. Don't worry, we won't get all up in your system. Just hit SUBMIT when you are ready to send your design...So how does this have to do with Grasshopper? Well, in order to track and provoke the growth, we use the info from your designed piece...all of that goes into a database which we can mine from Grasshopper / Rhinoscript. When the cloud finds an appropriate piece, it gets queued for fabbing...Grasshopper connects to this and shows us where there are holes, where we can grow, where we will have issues...I am attaching a small simple, quick, n dirty pdf explaining some of the functionality of the system.well, that's long enough. Let me know if you have any issues. I hope you will take part!…
