Bezier spans, i.e. N sequential points and tangents (still working on this one actually).
I could add more types such as tan, arctan, hyperbolic trig functions, square-roots, etc. etc. but I've got enough for testing purposes now.…
me of the things I think are issues still:
-In general, I'm a bit confused about the relationship between Length and Strength in the Length(Line) goal (and ClampLength for that matter).
-The data matrix needs to be cut in half (triangle rather than square) so that the lines don't repeat. That is, the first point/category needs to connect to 9 other points, the second then needs to connect to 8 points, the third to 7, and so on. This is what I was trying to accomplish with the Explode Tree and Split List functions in the middle.
-Because of this, I'm losing track of the order of the data, and so I'm not completely sure whether the point/category labels are matching up to the right points/categories.
-A few of the values in the matrix are 0, and I'm concerned that this may interfere with things. My goal is for the higher numbered connections (like E-H) to be closer together, while the lower numbered connections (like D-E which is 0) to be the furthest away.
A couple of other notes:
-Right now, I have an Absolute component in there so that negative connections are treated the same (I'm hoping to color these later).
-I kept the ClampLength goal, though I'm not using it. Given my other requirements, this might be the best way to go, though I'm not sure.
Thanks!

at STL files of "thickened" wireframes.
The problem underneath, is that we are not dealing with 2d or 2.5d meshes, but a bunch of lines, intersecting in 3d vertex, wich globally are not topologically related, but its ideally a 3d spatial structure.
As fas as we know:
option1: mesh/solid boolean
>between tubes, for the edges, and spheres at each vertex.
>it happens to get many errors in Magics & crashes quickly with big structures and many meshes.
option 2: isosurface
>either isosurf , or realflow works fine for high blending needs, and small pieces
>looks always good but does not seem to fit slender tubular structures fabrication purposes
option 3: 3-matic software
>used by prototyping industry, seems to repair everything
>expensive, unaffordable, exceptionally
option4: topological extrude
>topologically solve the extrusion of a vertex with many edges, generating non overlapped geometry. For 2d and 2,5 D, it works, but our attempts in maya fail everytime we try with 3D vertices.
> we believe there has to be a geometrical mesh trick
(we imagine Giulio Piacentino's Weaver Bird could have this useful feature)
We'll be waiting for suggestions and solutions (or cases)
Thanks

o a multiplication between two lists of N matrixes of 6x6.
So far, i've been working with them as data tree, therefore i have a "3 dimensional" setup(Paths are [X,Y}(Z))
i'm an absolute begginer in any programming language, but so far i've done something like this:ps: d is just an input, thats the number of dimensions,
both k and T are the lists of matrixes.well, i'm hoping to get one matrix list as an output, what is what i attempted by the c{m} up there, and if possible eventually(after some more operations) bring them back to data tree format.any ideas?Thanks!Bruno…

at keeps me from modifying 'easier' the structure (in the same time not much time to study it since its for school). What I am intending to do next is to create 2 vertical 'pillars' (always in space frame), placed on the extremities, which would have its starting points(of the lines that generates the frame) at the center of a certain sphere (for exampling for the length 3 spheres..)going perpendicular to the 'ground' (plan x,y). So I do understand more or less how it works and all, but don't know the use of many functions from GH (started using since september 2014)....
Could please someone help me, ( if possible explain me) how to do it what to use ( using a language for a Noob to understand) Thx to whoever responded to my help 'demand' and may you be blessed :D
if it makes it any clear what i need ;)…

I tried so many different ways but none worked !i need 3 layers, each layer has a different number of points, so there will be different size of holes. ( I think I've reached this point )I used a pop2d -> 2D Voronoi -> Scaled ( dist from curve ) but I want all three layers connected to each other, i tried also 3D Voronoi and the Voronax Plugin and none worked !I'm so confused :D

2013 | mayo 30, 31 y 1 de junio. 15 Hrs.
Horario: 18:00 – 22.00 Jueves, Viernes y Sábado de 8:00 a 16:00 Hrs. Instructor_ Arch. David Hernández Melgarejo.
http://bioarchitecturestudio.wordpress.com
Objetivos:
El curso está dirigido a cada diseñador, ingeniero o arquitecto que quiere obtener una sólida base en modelado generativo y paramétrico dentro del flujo de trabajo en Rhinoceros.
En el curso se explorarán y construirán estructuras en el espacio paramétrico, incorporando entidades geométricas (Curvas, Superficies, Puntos, etc…) y usando patrones algorítmicos.
Cada paso será soportado con ejercicios que gradualmente incrementarán su complejidad.
El alumno aprenderá cómo trabajar con asociación geométrica y parámetros. Para perfeccionar asociación geométrica – asociación entre partes, asociación dinámica – las formas geométricas son generadas al seguir la conexión lógica entre la parte geométrica y su restricción, dimensión paramétrica y él proceso dinámico del diseño: en pocas palabras estimulamos el pensamiento relacional.
Resultados:
Los participantes con éste entrenamiento obtendrán las siguientes fundamentos.
· Construir, modificar, depurar y correr aplicaciones de Grasshopper.
· Comprender el editor gráfico algorítmico y sus patrones usando grupos y cables conectores.
· Trabajar con dimensiones dinámicas, parámetros y listas.
· Generar aplicaciones orientadas a la documentación del diseño y la fabricación.
Palabras clave:
Diseño Computacional, Scripting, Rhinoceros 5.0 + Grasshopper, Parametrización, Análisis, Fabricación Digital.

ject that involves the design of an app that allows people to interact with a 3d model through some sliders.)
Ok, imagine you have a symmetrical shape like the one i drew:
What I intend to do is to have different 3 sliders that allow me to adjust the 3 distances (x, y, z) independently of one another.
-1st question: my idea is to draw the curves in rhino, then use the "divide" and "list item" components to extract the points I need. Is it correct? :D
-2nd question: the "move away from" component can be used in a symmetric way?
(I try to be more specific: with only one slider, can I move both points 5 and 6 simultaneously about the axis i drew?)
-3rd question: is there a way that allows the curves to reshape themselves as I move the slider related to the distance between a couple of points?
I hope I have been clear ;) I would greatly appreciate any help you can give me!

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:

ies of reference boxes and using the Box Morph component.
So far I've had some success, as shown in the image. However a few things have cropped up (probably not helped by my limited GH skills!)
1- The morphed geometry isn't aligned. I have ensured the original points match point for point; I have a feeling the u&v directions might have swapped?
2- So far I have been splitting the complex geometry manually in Rhino and defining manually in GH, then matching reference box to target box one by one. This was more for the sake of expedience, and to see if it worked; however I feel there must be a better way of doing this. Maybe the reference boxes split the complex geometry, then test for any contained geometry (the 'Inside' component?)
3- I feel there might be a better (existing!) solution somewhere, as I can't be the first person to try this!
I've attached an image of what I'm trying to do + the definition. The .3dm file is 12MB, I can send it upon request :D
All help would be much appreciated, thanks…
