mpression bending test apparatus has been developed to measure the flexural properties of plywood-fiberglass composite slender beams. The number of fiberglass layers and the orientation of the fibres along the strip have been examined, in order to calibrate the bending behaviour of each strip segment, aiming to encode complex 3d form into flat 2d strips, which bent and anchored at both ends, form non-symmetrical arch shapes of variable curvature. The results show that the proposed method enables a unified materially informed form finding process, where the geometry is approximated according to local material specifications at macro, meso and micro scale. Informing physics based simulations with material properties data derived from the proposed mechanical testing scheme, allowed for fairly accurate material behaviour simulations, with deviations attributed, besides the non-standardized apparatus measurements, mainly to the manual fiberglass layup and the number of mechanical tests conducted for the calculation of the mechanical properties of each fiberglass layout variation.

onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. The evaluation of the definition's ability to handle different point cloud data sets.
3. Video reports with the definition's results, animating subsequent per deviation step frames.
This definition calculates best fitting plane deviations. The number of manual set parameters has been minimized to two the facade per World UCS axis selection and the search width. This defines a box, which is used to crop protruding architectural details, which do not contribute to the analysis, but also ensures that large deformations are included in the calculation.
For the automation of the vertical and horizontal sections creation, the analyzed cloud is clustered, according to user defined number of 2d grid cells. The deviations corresponding to each cell are averaged in mean and median mode.
The process is displayed mostly in real time, with some speed up in some parts. Too long calculations have been omitted during video edit. The setup is responsive and benchmarks show that changing between dense point cloud data sets and facades is pretty quick (6.5-7.5M points, 25-45 deviation steps, 44x22 clusters), updates are calculated in acceptable timings (3-6 minutes).
I would like to thank Heumann A. and Zwierzycki M. who provided direct support with HumanUI and Volvox. Also Grasshopper3d forum users Maher S. and Segeren P., who contributed with Rhino viewport manipulation scripts.

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.

giornata inaugurale sarà dedicata alla free-lecture introduttiva finalizzata alla realizzazione di un modello d'architettura complesso attraverso l'utilizzo di comandi e tecniche avanzate di rappresentazione con Grasshopper (plug-in parametrica di Rhinoceros) e 3dsMax. Sarà illustrato inoltre il potenziale di V-ray per 3dsMax realizzando un rendering concettuale. Durante il mini-corso dell' openDAY verranno mostrate le caratteristiche e le potenzialità degli strumenti per far luce sui nuovi valori assunti dalla modellazione 3D. La modellazione 3D sta interessando un pubblico sempre più vasto inserendosi in una nuova fase di ampia disponibilità per conoscenze, software, hardware di prototipazione e modelli. Pur mantenendo tutti i suoi valori già noti la questione si è talmente ampliata fino ad interessare norme giuridiche (diritti sui modelli ,concorrenza con offerte di servizi apparentemente simili, informazioni deformate e onfusione nei media) Makers University[http://www.makersuniversity.com], in collaborazione con parametricart, vi propone un punto di vista ampio e sintetico su queste tematiche.
Al termine della free-lecture, sarà illustrata l'offerta formativa [CLICCA QUI] di parametricart riferita ai corsi che si terranno nei mesi di Gennaio e Febbraio 2013 inseriti all'interno della più ampia programmazione della Makers University. SONO PREVISTE TARIFFE PROMOZIONALI PER COLORO CHE SI ISCRIVERANNO AI CORSI durante l'OpenDAY.
La lezione e la presentazione si terranno nel nuovo spazio co-working il PEDONE.
PROGRAMMAZIONE
- I temi della Makers University [Leo Sorge];

ial-by-nao-box-morphing/), but there are several reasons as to why it wasn't suitable for what I'm trying to do;
1. I'm interested in using a 2D pattern rather than a 3D form, which will then be repeated within a Paneling point grid which is assigned to a surface. The repeated patterns are then pulled onto the surface, which are then used to trim the surface.
2. The surface I'm using has high curvature, and using box morphing intersects the surface, so it doesn't conform to the surface as closely as I'd like it to unless the number of repeats along U and V are increased.
3. The surface I'd like to use has various trimmed regions on it. Paneling Tools is great for me, because the 2D pattern is repeated on a Surface Domain point grid, so it is initially repeated over the the trimmed regions, but once since the Pull setting is used, only the repeated pattern curves that lie over the kept surface remain (see Paneling tools jpeg).
The surface I've used in the images isn't the surface I need to use, but hopefully it shows what I'm trying to do. Also, I've managed to get the patterning that I need on the paneling tool example, but the reason why I want to use Grasshopper is that it allows me to scale up/down the UV ratio of the paneling points by using a slider tool, so the user can change the pattern density. The only trouble with this is that I can't bake the points out of Grasshopper into Rhino so I can use paneling tools.
Also...I'd quite like to know how the VB module works, because I'm curious, and I'd like to learn more!
Sorry if this is a bit wordy, but I can't think of a better way of explaining what I need.

up before you can produce a nice render. If you are using vray for Rhino you need to first learn how to set up (as an architect) a nice solar daylight system with environment, is actually very easy. (1 - set up sun lighting, 2 - set up environment, 3 - choose correct settings, such as activating indirect illumination)
However, since sketchup is the perfect draft tool for architectural design, it happens to have an environment with daylight defined already when you open an empty file. Vray for sketchup knows how to use all these settings so the only thing you need to do is to hit render. Apart from that you need to learn some simple material settings, which you find here: http://www.vray.com/vray_for_sketchup/manual/, the same manual for rhino here: http://www.vray.com/vray_for_rhino/manual/
The advantage of using vray for sketchup rather than for rhino (although if you can handle vray for one program its exactly the same for the other), is that you can easily import models from 3d warehouse. Sketchup is an excellent render set-up platform, except its only 32-bit so a to complex scene will simply not render. Rhino 64-bit will handle this better.
Conclusion, learn vray, whatever you learn can be applied to sketchup, rhino and 3ds max. Sketchup is probably a tool you already use and vray for sketchup will render with correct settings by default. Later when you take it to the next step you can go one and learn vray 2.0 for 3dsmax.
Personally I like using Luxology render engine that comes with Microstation, simply because I handle it better and Microstation is the best tool for architects in my opinion. However Vray is similar but more powerful.…

something in 3d, explode it to single surfaces, reference it to GH in proper order -manually- then unfold it with gh).
To make it really elegant you could try to make some "topology language" - have you seen this talk by Robert Lang http://www.ted.com/talks/lang/en/robert_lang_folds_way_new_origami.... ?
You can always make only few parametric types of structures - like leg, hand etc. (this is much easier than Mr.Lang's ) which can change its sizes, but topology stays the same.
Beside - Your sandwich looks really good, i played something similiar before.... have you tried thin PE (polyethylene) sheets ? Its similiar to PP (polypropylene) but a little bit softer. It is (PP) commonly used as tic tac box cap ( http://www.absolutelynarcissism.co/wp-content/uploads/2011/09/Tic-T... ) and some say that it can fold/unfold about 1000000 times. It would really simplify the whole production (just one cnc router needed to obtain full structure). Of course bending it will require prefabrication to look like e.g. http://www.grasshopper3d.com/video/the-swarm-2012 by Mr. Wieland Schmidt.
To clear things up :
1. It certainly can be done with rhino/gh
2. You should write some more on how should it all work (what you provide as geometry)
3. You should also provide some more info how 2d drawing looks now.
EDIT : I forgot about kinematics - use kangaroo. There are forces now like bending resistance etc.

ont. outputs 2 lists. a with neighbors in front and b without.
i have attached a final screenshot, a rhino testfile with ca points and the final definition.
this is the code:
'Declare and Initialize data
Dim i As Integer = 0
Dim j As Integer = 0
Dim pts_count As Integer = pts.Count() - 1
Dim new_ptsA As New List(Of On3dPoint)
Dim new_ptsB As New List(Of On3dPoint)
Dim temp_pt1 As On3dPoint
Dim c As Integer = 0
'Loop through base points
For i = 0 To pts_count
c = 0
For j = 0 To pts_count
If pts(j).x = pts(i).x And pts(j).z = pts(i).z And pts(j).y = pts(i).y - 10 Then
Print("neighbor in front")
temp_pt1 = pts(i)
new_ptsA.Add(temp_pt1)
c = 1
End If
Next
If c = 0 Then
Print("NO neighbor in front")
temp_pt1 = pts(i)
new_ptsB.Add(temp_pt1)
End If
Next
'Assign new points
A = new_ptsA
B = new_ptsB
be aware that the code assumes a grid width and depth of 10x10.

nd and downloading definitions to learn from them, but still don't get it right.
So my problem is:
1.- I want to achieve a kagome, hexagonal gridshell that keeps the bamboo pieces like straight geodesic lines.
2.- I also would like to keep the curved bamboo as splines, so I imagine this will give the easiest method for bending the bamboo at the real scale. As Mårten Nettelbladt in his blog http://thegeometryofbending.blogspot.jp/ mentions, the best way will be to keep the geometry where all the pieces have a spline curvature ( or as B.K.P. Horn calls it “The curve of last energy”) In order to achieve splines do I need to make the grid a Dynamic relaxation “Kangaroo”? will this help?
3.- I would also like to simulate the bending of the elements from a 2D to a 3D, but maybe this can be a next step on the definition…
Some of the common problems that I notice in the definitions found is that when people do weaving, the lines don't bend flat to the geometry but rather they twist so when you look close the cross of pieces intersect, which is impossible in real life…
As you can see there are a number od issues here, I apologize to put them all together, maybe it makes this confusing but I think is better to look at the whole picture. I have been reading a lot but I have no idea how to start.
The more I read the more interesting the subject becomes but the more confused I become. Is there some kind soul that could give me a hand? Any help will be really appreciated.
Thanks a lot!
Miguel…
