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

that are available, I found myself in a quite difficult problematic.
I did a lot of google search/work and found some information, but still kind of haven't got the information that I need or want to use. Note: Our school has provided us 3 hours of basic Grasshopper tutorial and one hour of Honeybee/Ladybug temperature tutorial (with weather data etc).
For now I have used Grasshopper and Kangaroo, haven't quite implemented other plugins.
What I want to achieve?I want to create a basic wind simulation in a room (cube at first, but then add more space and use different models) that I can change inside grasshopper. For example I have two openings. I blow wind inside the object from one opening and it goes out the other opening. When I change the wind parameters I can analyse the wind and data that is flowing through the cube.
Is there a way I can visualize the wind?
I have seen different solutions, but mainly vectors with colors that are visualized as wind direction and temperature. Is it possible to make it 3D that I can actually make a real-life model out of it?
Why cube?At first I want to test it and see how it works, if it is viable or not. In the end I would create a facade that is designed for natural ventilation. I am kind of trying to put two projects together. One for the wind analysis, the other for the 3D-Result that is created with the wind. It might be a quite awful that I am asking, but I don't know where to go after doing the google research. Also, some Grasshopper links I found that might help describe the situation. http://www.grasshopper3d.com/forum/topics/wind-analysis-by-grasshopperhttp://www.grasshopper3d.com/forum/topics/wind-cfd-change-form(Should I approach it with Ladybug and Ecotect?)

sinergetici associati alla compresenza simultanea di differenti strumenti di analisi e digital design all'interno di un processo di progettazione in svolgimento. I partecipanti utilizzeranno Grasshopper (modellatore parametrico per Rhino): l'uso di questo editor grafico di algoritmi si integra alla perfezione con gli strumenti di modellazione di Rhinoceros 3D espandendo le possibilità di corstruire modelli parametrici altamente complessi. Per generare una complessità simile saranno utilizzati collegamenti live ai diversi programmi elencati di seguito: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI Durante questi intensi 3 giorni, i partecipanti impareranno il workflow dei plug-ins con l'aiuto di esempi esplorando una panoramica dei differenti software, le possibilità di testare le performances di un progetto o l'uso di strumenti addizionali non legati ad un singolo sistema (es. accentuazione, formazione, reazione parametrica) [english text] The focus of the workshop is to integrate and correlate the synergistic effect associated with simultaneous presence of different digital design- and analysis tools in an ongoing design process. The main attention is set on easy to handle interface , which should be used at a early stage of conceptual design to respond to external and internal influences in a intelligent and sustainable way. Participants will use the software Grasshopper as a parametric modeling plug-in for Rhino. The usage of this graphical algorithm editor tightly integrated with Rhino's 3-D modeling tools open up the possibility to construct highly parametrical complex models. To generate this complexity we will use live linkages to several programs listed below: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI In this 3 intense days, the participants should learn the workflow of the plug-ins with the help of examples and get an overview of the different software's, there possibilities for evaluating the performance of a design or the usage of additional tools to be not chained to a single system .

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.

ow..
It's basically using a 3d framework to define points on the framework and then interpolate curves through them.
Right now Im assuming that I merely translated something incorrectly early in the script that lead to most of the definition issues later on...?? It also seems I am not using the append function correctly... :(
If anybody well versed could take a look it would be awesome... :)
The code I've used is below and the erros I get are attached here:

bject of this edition focuses on the investigation of interactions between the environment and the human being, made through objects, mechanisms and architectures able to interact with who makes use of them. The aim of digitalMed IV is drawing a catalogue of projects/prototypes to insert them in an urban context, and to outline new future-cities profile.
PURPOSES AND TERMS:
The digitalMed Summer School IV edition aims to organize the flows of information, in which the city is absorbed, to adapt projects and to make them useful, no invasives, and suitable to establish an information exchange.
The concepts of slow cities and smart cities are directed by all types procedures, from immaterial to materia, from information to the built. This is the iter that we will follow to reinvent the relationship between man, environment and cities.
Through learning by-doing educational procedure, participants will acquire not only new metodologies and means, but also concrete cases where testing these ones. In this way, new acquired information won’t remain simple educational exercises, but will be notable elements in the portfolio participants.
TOPICS:
The planning approach of digitalMed Summer School IV edition will supply to participants all the technic knowledges and theoretical bases in order to work.
The first days of workshop will focus on the outline of a shared vocabulary that allows to work from shared meanings. This phase is characterized by subjects occurring in the contemporary architecture such as computational design, digital fabrication and data driven, then systems, like Arduino, which allow the interaction with objects, and fields like permaculture and social innovation that nowadays contribute to the realignment of environment and city’ ideas.
The participants will have the opportunity to learn the use of software for the parametric planning, like Grasshopper, and to test interactions between real information and virtual data (and viceversa) through the use of Arduino.
PREREQUISITES:
The workshop is open both to the students and to the professionals. It needs a basic knowledge of Rhinoceros 3D program. All the participants have to bring their own laptop. The programs for installing will be communicated during the registration act.

ake a network of lines (i.e. a graph) and make a Plankton Mesh, from which you can use Cytoskeleton to make a solid mesh (and then smooth it with Weaverbird).
Works with ngons (polygons with 3 or more sides). Other examples I found only worked with tris and quads.
Works on open or closed surfaces
While these examples start with a surface, you could start with a network of lines and make a patch surface
This is meant for 2D networks/surfaces. I haven't attempted filling a 3D volume. My guess is this wouldn't work as it would require a non-manifold mesh that Plankton wouldn't handle.
Note similar results could be achieved with the following:
TSplines
MeshDual (dual of a tri mesh, not as much freedom/control)
Working backwards, here is the GhPython script from Will Pearson that builds a Plankton Mesh from vertices and faces. The vertices are a list of 3D coordinates, the faces are a tree a lists, with each list containing the indices of vertices that form a closed loop. From Will, "Plankton only handles manifold meshes, i.e. meshes which have a front and a back. This orientation is determined by the "right-hand rule" i.e. if the vertices of a face are ordered counter-clockwise then the face normal will be out of the page/screen."
# V: list of Point3d # F: tree of int
import Grasshopper appdata = Grasshopper.Folders.DefaultAssemblyFolder
import clr clr.AddReferenceToFileAndPath(appdata + "Plankton.dll")
import Plankton
pmesh = Plankton.PlanktonMesh()
for pt in V: pmesh.Vertices.Add(pt.X, pt.Y, pt.Z)
for face in F.Branches: face = list(face)[:-1] pmesh.Faces.AddFace(face)
These vertices and faces are precisely the output from Starling. Starling takes in a list of Polylines which form the (properly oriented) face loops.
The polyline face loops can be generated...
Directly from Panels on a surface using LunchBox
Using any network of lines/curves on a surface (curves will need to be converted to polylines before Starling)
The latter was achieved using the Surface Split command, then converting the face edges (converted to curves) into polyline loops to represent faces.
…
hope this number will grow in future. Currently available features are:
1) Creation of 2d or 3d context for any kind of building related analysis: automatically generate the 2d/3d surrounding buildings for the location where you would like to perform visibility, solar radiation, cfd or any other type of analysis. You need some other plugin for the last three, like Ladybug. It only creates the context=surroundings! The "automatic generation" process also includes creation of the local topography (terrain) along with buildings.
2) Identification of certain 2d or 3d elements in the created context. For example: selection of all hotels, parks, hospitals, restaurants, residential buildings etc.
3) Performing direct terrain analysis (hillshading, slope, ruggedness, roughness, water flow...)
4) Creation of terrain shading masks and horizon files for further solar and photovoltaics analysis.
Gismo will be very grateful if he could get any suggestions, improvements, bug reports and testing in the following period. In case you are willing to provide any of these, the requirements, installation steps and .gh example files can be found here, here and here.
Thank you in advance !!…

Introduction to Grasshopper Videos by David Rutten.
Wondering how to get started with Grasshopper? Look no further. Spend an some time with the creator of Grasshopper, David Rutten, to learn the
onstrates the following:
1. The definition's functionality employing HumanUI for the custom user interface.
2. Color based segmentation in manual and auto modes.
3. The evaluation of the definition's ability to handle different point cloud data sets.
This definition performs color based segmentation in two modes.
A manual mode, that implements the Delta-E CIE 2000 color difference formula, for targeted feature detection. An auto mode, that employs a simple RGB Color Range algorithm for quicker preliminary results.
RGB to XYZ to CIELab conversion and Delta-E scripts were based on Colormine's project code from github. Results have been compared and verified with the results of http://colormine.org/color-converter and http://colormine.org/delta-e-calculator/Cie2000.
Each stored class is charted and can be accessed through the UI, as shown at 2:30, where Delta-E CIE 2000, in CieLab color space, output results were found to be in perceptive conformity with human eyes, far superior to the preliminary RGB implementation.
Initial definition versions could process highly subsampled clouds in acceptable timings. Further research showed that employing the multithread processing of Volvox components, bundling the Delta E formula with the RGB to CIE lab color conversion script, per color segmentation calculations for a one million points point cloud would go down from 23 (c# script component) and 8 (vb script component) seconds to approx. 1 second (volvox script cloud component), thus allowing the segmentation of less subsampled point clouds.
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.
