ails.
Some word about the mesh... (see Image_01)
I took a flat 4 points NURBS surface as imput (very easy, it defines the total area of my pavilion) and some points (that defines the contact with the ground).
Then I extracted a grid of points from the NURBS (Surface_Util_Divide surface) and compared 'em with the contol points, in order to associate to each grid's point its own attractor (Vector_Point_Closest Point).
Than I moved the points down. I used the distance from each point to its attractor (inverted) as amplitude for the vector of the movement, in order to say: the nearer you are to the control point, the more intense your movement will be. During this operation I've passed the distances' data list into a graph mapper (Params_Special_Graph Mapper), in order to regulate in a very intuitive and interactive way the shaping of my canopy.
At the end of the process I asked GH for a simple Delaunay mesh (Mesh_Triangulation_Delaunay Mesh). It's a very cool command, I believe!!!
Ok, now some word about the component, it's design and it's repetition/adaptation to the mesh...
(see Image_02)
I took the mesh and extracted components on first and faces's information on second. Then I selected and separated the vertexes (1°, 2°, 3°) of each triangular face into threee well defined list.
Then I re-created the triangles' edges. Please pay attention because it's not the same if you use output information from Delaunay components, because here we need a justapposition of edges where triangles touches each others.
After this work I joined the edges and found their centroid. At the same time I found the mid point of each edge.
Now the component... (see Image_03)
It' a little bit longer to describe: I'll try to be synthetic.
Substantially it is a loft from a curve to a point, repeated three times for each triangle (Surface_Freeform_Extrude Point). The point is an elevation of the centroid of the triangle (you can choose if the exstrusion has a single height or it's related to an attractor. In my case it was fixed). The curve is combination of things. There's an arch, which starts on the edge (there's an offset from the corner) end terminates on the same edge (on the other side, obviously). While it's generation the arch passes through a third point which belong to another segment. This last connects the mid point of the original edge (base triangle) with the centroid. The result is a kind of polyline, with two segments and an arch. If you go back to the image of the component that I posted probably you'll understand what I'm saying better than with the definition.

nter the programming world and tinker more complex, interactive solutions. We will also explore advanced programming paradigms. There is no class official programming language, as both C# and Vb.Net are possible on the participant’s side, and all examples will be provided in both C# and Vb.Net. Additionally, we will see how to get started writing full .Net plug-ins. Finally, we will have time to explore user’s own proposals on the third day.
Day 1 Morning: programming introduction in .Net
• The Grasshopper scripting components. Choosing a .Net language. Language developments
• Variables declaration, assignment and utilization. Operators. Methods [functions]. Calls
• Classes: declaration and instancing. Constructors. Importing a namespace. On3dPoints, OnLines
• Arrays declaration and usage. Lists. Adding to arrays and lists, advantages and opportunities.
Afternoon: patterns
• About OOP (object oriented programming) as opposed to procedural programming. Discussion
• Example of OOP good code reuse: sorting points by coordinates using the .Net SDK classes
• Lists as input parameters. Trees as input parameters. Usage and limitations
• Finding resources: on the net with website that can help getting started and troubleshoot. And books
Day 2 Morning: extending Grasshopper functionality with our definitions
• Store data between updates. The use of fields [globals, or static locals]
• Examples on how to use stored data between updates: a simple agents simulation
• Baking geometry with scripting directly into the Rhino document. Baking with names
• Passing custom types from a scripted component to another one. Our own code reusability
• Rendering an animation from Grasshopper. How to get started and final results
Afternoon: customizing our tools
• Our Rhino plug-in with Visual Studio C# [Vb.Net] Express Edition & wizard. Parametric mesher
• Writing a custom Grasshopper component: hacking an exporter for our data to Excel
Day 3 All day: personal project
• Rehearsal on any example from the first two days. A project that you want to start on your own, being it a Rhinoceros plug-in, a Grasshopper assembly or a script. Example might be to send data through network with UDP to Processing
MINIMUM REQUIREMENTS
A good foundation of Grasshopper visual programming is mandatory. You will need a level which corresponds to the Grasshopper 101 course outline. Examples of things that will not be covered in this course are: sorting document spheres by diameter, paneling of a surface with grasshopper components. You are expected to already know these from the Grasshopper course.…
to host the annual parade of Samba Schools during the Carnival festival. For the remaining 361 days of the year it stands empty and desolate as a massive dividing wall within its degraded urban context. Renovated in 2012 and now the future site for the 2016 Olympic marathon finish line and archery events, the Sambadromo is receiving renewed international attention, but it drastically needs to accommodate new types of programme and improve its connection with its surrounding context. AAVS Rio de Janeiro will explore ways to intervene within and transform the Sambadromo, with a potential focus on the VIP and Press Rooms ‘camarotes’, which were originally designed to house classrooms when Carnival was not taking place, and are now the site for over-commercialized, under-designed temporary installations during Carnival, and abandoned throughout the rest of the year. Teaching team:The teaching team will be led by Elena Manferdini, from Atelier Manferdini (www.ateliermanferdini.com), to teach and use advanced digital design and fabrication to generate iterative transformations in the creation of new micro-infrastructures. Computational and fabrication skills: The workshop will teach advanced computational design skills. A series of physical models will be built using digital fabrication techniques, such as laser-cutting and rapid-prototyping, that will be taught during the workshop. No previous digital or fabrication experience is needed.

Il corso introdurrà il software Grasshopper, plug-in per la modellazione parametrica in Rhino. I partecipanti saranno guidati attraverso gli aspetti più importanti del programma e le principali tecniche per la programmazione visuale all’interno di Rhinoceros. Il corso è rivolto a studenti con esperienza minima nella modellazione 3D e si articolerà in lezioni teoriche ed esercitazioni. Sarà rilasciato un attestato di partecipazione.

Sorry! But the number of available CPUs on your machine is 4.
Honeybee set the number of CPUs to 4.

@Mostapha, if it is indeed a different issue, what do you think it could be?
Thanks again,

e surfaces (in both directions) according to an input length I set?
2. [refer to image: split surface, butt joint case]
Then can I control where the split occurs? Because if all splits happen at the same positions, the waffle would not be structural.
3. [refer to image: split surface, with gaps case]
Another situation is to control where the split occurs, but gaps are created at the split. How can I get this done? This has reference to the AA pavilion.
Files attached.
Thanks for help,
Fanny
