surface between 2 cross-listed series of points which happen to be "Divides" of the edges of the 3D surface (some kind of planar geodesics if you want).
To do so, I am extracting the intersections between the 3D surface and a series of planes that are rotated (with an angular increment defined as precision) around an axis defined by the straight line between the points.
Hence I end up with a bunch of planar curves. I need to extract them and order them into lists (1 list per pair of points) to extract the shortest curve between each pair of points.
If the first list of point is numbered: 1, 2, 3, 4..... & the second list is lablelled a, b, c, d.....
I can't find a way to extract the shortest point curve of the list between
1 and a, and between 1 and b, and between 1 and c, ... and between 2 and a, and between 2 and b, ...
I think the problem would be fairly easy to solve if I could use VB or Python or any code but I dont know how to code and I am in quite a rush to hand the project in..
Also, I have been using a Python component downloaded from this forum which evaluates if a point is on a curve and returns the point. I modified the code so that it returns the Curve instead of the pt.
If you guys have an idea how to solve this, you would clearly be my saviour :)
Here are a 3dm, the gh and the python component. I have also been using the Kangaroo component that kills duplicate curves..

almost 60 seconds to compute, 50x50 points x 35 samples each x 3 rectangles = more than a quarter million curve|curve intersections), but at least not fossilised dog slow.
The inputs of the component are:
P = Plane in which to shoot the isovist sample rays, plane origin equals sample point
N = Number of rays per sample point
R = Maximum radius of sample rays. Any obstacles beyond the radius are ignored
O = List of obstacles (curves only). They will not be projected onto the sample plane, so you can have curves that are only partially 'active'.
Outputs:
P = Point at end of ray (at distance R from sample point) or point at closest obstacle along ray view direction.
D = Distance from sample point to P
H = Boolean indicating whether the ray hit an obstacle or not

2. In what sort of animal these "shaders" are to be used? Meaning that designing a "Viz" control for 2345,67 mini-membranes is one thing and doing it for your house is a totally different challenge. In plain English: it's more than possible to hit the Wall if lot's and lot's of items are invited to the party (you bring the girls and I'll provide the Vodka).
3. Do you like the idea of completely separating (on a spatial basis) input/viz control (what is on display and on what level of "detail") from the core logic (i.e. components). Pros: obvious, Cons: obvious.
4. Is this def planned as a "constant" evolution thing? Meaning that using, say, the mapper isn't the best idea if your input goes from {a;b;c} to {a;b;c;d;g;...;z}.
5. Have you any - even academic - plans (see 1) to walk the walk up to the end?. Meaning talking to Birdair/Taiyo Kogyo etc etc ( http://www.birdair.br.com/ ). If yes be prepared because these fellas work a bit differently as regards potential collaboration and feedback at design phase.
BTW: the thing that would change the world as you know it:

ilion.
Then i sketched the outline curves in rhino with a few control points. The building is symetric so i only draw one side. But i'm not sure what is better for a voroni. a sharp or a soft surface? Or dose i need points?
So i have some questions:
1. how can i loft the curves correctly? My problem is that if i divide my curves for more control points, grasshopper automatically change my curve. thats ok but than i've the problem with a short curve, which fit bevor with the large one, but after the devision it can't connect.
So i tryed to duplicate the long curve and split it but with the shatter battery it dosen't work. It always cut the curve somewhere.
2. my next problem is, the curves in rhino should be my main construction, which is always visible. so i decided to offset the curves that i got a colum. but i don't know how to orient the offset curves in the xyz axis.
3. hopefully if i have the surfaces, how can i build a voroni which is offsetet, and has maybe some different thicknesses? :D
Would be really great if s.o. can help me. I tried a lot but not every thing is simple.
Sorry for my bad english.
Thx max

d the workshop PDF from this link: http://goo.gl/bcvRNH Download event poster from this link: http://goo.gl/Q0KWCM Brief: Cairo is filled with barriers controlling people movements, suppressing them as well as detaining green and public spaces to the extent that most people have been taking these spaces for granted. Public spaces have been for a while the periphery of our daily life. We will explore in this workshop how we can manipulate and alter people’s perception and direct their attention to how these spaces are integral for city life. This exploration will be backed up by intensive technical tutorials introducing computational design and fabrication techniques and tools mainly Rhino, Grasshopper, Geco and Ecotect. Not only will this be the typical technical workshop, but rather you will also have the chance to be guided step by step on how these tools are used through out different design stages in a real world scenario. Design prototypes will be produced through 3D printing, the main workshop output will be a fabricated one to one functional model for one of the designs using our new in-house CNC machine. Tutors (check the PDF for bio): Olga Kovrikova, MArch DIA Alexandr Kalachev, MArch DIA Karim Soliman, MArch DIA Islam Ibrahim, MArch DIA Sherif Tarabishy, B.Sc.

occur more than once in the same list, and different elements with identical values can occur more than once. Also, a list may contain lack of elements, referred to as "nulls".
Sets. Strictly speaking a Set is a mathematical construct which adheres to a strict collection of rules and limitations. Basically, a Set is the same as a List, with the exception that it cannot contain the same element more than once, or indeed two or more different elements with the same values. You see, in mathematics there is no difference between a value and an instance of that value, they are the same thing. In programming however it is possible to store the number 7 in more than one spot in the RAM. Grasshopper does not enforce this rule very strongly though, you can use a lot of Set components on lists that have multiple occurrences of the same value. The big difference between Lists and Sets in Grasshopper is that Sets are only defined for simple data types that have trivial equality comparisons. Basically: booleans, integers, numbers, complex numbers, strings, points, vectors, colours and intervals. Lists can contain all kinds of data.
Strings. Strings are text. There's nothing more to it. I don't know why early programmers chose to call them strings, but I suppose it's a better description of the memory representation of them. Strings are essentially sequences of individual characters.
Trees. Trees are the way all data is stored in Grasshopper. Even when you only have a single item, it will still be stored in a tree. A tree is a sorted collection of lists, where each list is identified by a path. A specific path can only occur once in a tree, when you merge two trees together, lists with identical paths are appended to each other. Trees are an attempt to losslessly represent not just the data itself, but also the history of that data. Imagine you have 4 curves {A,B,C,D} and you divide each into 3 points {X,Y,Z}. Then, for each of those points you create a new line segment {X',Y',Z'} and then divide each of those line segments again into 5 points each {K,L,M,N,O}. The way data is stored in trees, it should be possible to figure out whether a point M belongs to X' or to Z', and whether that X' or Z' came from A, B, C or D. This is why paths are often quite long after a while, because they encode a lot of history.
Paths. A Path is nothing more than a list of integers. It's denoted using curly brackets and semi-colons: {A;B;...;Z}. A Path should never be empty {} or have negative integers {0;-1}, but it is certainly possible to create a path like this and it probably won't even crash Grasshopper. Paths are 'grown' by components that (potentially) create more than one output value for a single input value. For example Divide Curve. It creates N points for every single input curve. In cases like this a new integer is appended to the end of the path.
In the next release the Path logic in Grasshopper is somewhat different. I fixed a number of obscure bugs (hopefully without introducing new fresh bugs) and special cased certain operations to somewhat reduce the speed at which paths grow. This may well break files that rely on a specific tree layout, but I hope the temporary sacrifice will be worth the long-term benefits.

io, alle ore 19:30 presso la Mediateca MARTE di Cava de’ Tirreni (Sa), la lecture magistralis dell’arch. Walter Nicolino dal titolo “Augmented visions / Responsive spaces”, un viaggio culturale che, attraversando gli studi progettuali a diverse scale condotti tra la sede torinese e il centro ricerca di Boston, mette in luce una attitudine nell’indagare e nel dar forma alle interazioni tra le persone, gli oggetti e gli spazi, al fine di fornire possibili risposte alle nuove istanze poste dalla rivoluzione digitale.
In apertura i saluti istituzionali del sindaco Marco Galdi, mentre a introdurre la lecture l’arch. Amleto Picerno, promotore del Mediterranean FabLab di Cava de’ Tirreni e tutor della Summer School digitalMed, il laboratorio progettuale che da quattro anni a questa parte, indaga temi, pratiche e tecniche dell’attuale panorama architettonico internazionale. È la smart city al centro della IV edizione di Summer School Digitalmed 2013, che si svolge a Salerno dal 22 al 28 luglio con l’obiettivo di creare un sistema di relazioni e di interazioni continue tra la città, le persone e l’ambiente in cui queste si rapportano in un continuo scambio di informazioni.
Ad esprimere la critic ai prototipi di progetto che emergeranno dal workshop digitalMed, sarà proprio Walter Nicolino, architetto di spicco del panorama italiano, coinvolto in numerosi progetti di ricerca al Senseable City Lab del MIT di Boston, insieme all’arch. Carlo Ratti con cui è fondatore e socio dello studio torinese CARLORATTIASSOCIATI.
Il 26 luglio lo space 1.0 della Mediateca MARTE di Cava de’ Tirreni si fa, dunque, arena d’avanguardia per un interessante dibattito durante il quale, a proposito della Summer School digitalMed, si ragionerà anche sul modo in cui le tecnologie digitali influenzano l’architettura.
«Da qualche tempo a questa parte possiamo scegliere se orientarci alla perfezione tramite navigatori GPS o perderci come sognanti flâneur metropolitani; possiamo associare in un batter d'occhio infiniti layers di dati a un luogo, oppure contemplarne in silenzio il paesaggio; possiamo anticipare la realtà con sofisticate rappresentazioni virtuali, oppure esercitarci in giocose autocostruzioni partecipate.
Possiamo avere l'una e l'altra cosa: non si tratta di una scelta tra il mondo reale e quello virtuale, come predetto da parte della letteratura agli albori dell’era digitale, ma si tratta di capire come il nostro ambiente costruito e gli spazi in cui viviamo stiano imparando a parlare un nuovo linguaggio e ad interagire in modo sempre maggiore con le persone - afferma Walter Nicolino che parafrasando Le Corbusier “La civilisation digitale cherche et trouvera son expression architecturale”, sottolinea l’importanza di integrare le nuove tecnologie e radici locali senza perdere la visione e la dimensione umana della città: All’architettura è richiesta una revisione dei propri strumenti per creare spazi flessibili, inclusivi, in grado di adattarsi ai nuovi modi di vivere e lavorare e di rispondere in modo interattivo alle nostre esigenze».
