r (top left) is connected with the list which contains the centroids of every triangle of my mesh (my canopy, that I turned into a series of triangular surfaces). In this part of the definition I evaluate the Z coordinates (extracted form the points).
I execute some operations in order to have my values from 0 to 1 (parametrization). Then I sutracted the lower value of the list to all the data. So I obtained a new list of numbers, which stay from 0 to 1 and I can use in order to determine a gradient in the arch openings.
The result? If you look carefully to the rendering I posted you'll see that the arches are less opened near the ground and more opened near the top. It's a structural way of design the canopy. The more loads you must support, the more closed your arches will be (and the more stronger you should be).
Anyway consider this part as not important, because this parameter is just a my interpretation, it's not essential in order to obtain the canopy I posted. If you want you can just substitute that emitter with a simple number, from 0 to 1. Don't know, try to put 0.4 as an imput and let's see what happens. The result will be more similar. ;-)
Nice to meet you Morgan.…
tecture: Realtime Physics for Space Planning
http://vimeo.com/15563685
"This is a preview of a parametric conceptual design tool for architectural
practice that I have been developing at NBBJ. I wanted to develop a
system that allows designers to quickly organize and understand complex
architectural programmes in three dimensions.
It is an advancement of the traditional bubble diagram; it solves
adjacency requirements automatically and suggests planimetric and
sectional relationships. The resulting diagrams are not formal
solutions; they are simply organizational diagrams with solved
adjacencies and accurate required areas. The diagrams are raw
materials, meant to be manipulated sculpturally, or even squeezed into a
formal container.
Technical Information
The tool was created in the Grasshopper plug-in for Rhino. Custom components, written in VB.NET,
read programme data directly from Excel into Grasshopper. The tool
uses the Kangaroo engine for realtime spring dynamics simulation."

green & B in red. These surfaces are at the centerlines of thicker beams in the model (not shown).
I have a list of "Intersections", the yellow vertical lines, usually four at each point the beams intersect (85 points or 340 intersections expected, though there are only 335).
What I'm trying to do is "get" the list of yellow vertical lines for each beam and keep them "associated", so that I can re-orient them with the thick beams in a flat, "nested" layout.
These intersections will appear in two sets of lists, one for beams "A" and another for beams "B".
I found and hacked a bit of C# script to partition the sorted list of indexes but not the related list of intersections ("Line-like Curves").
In this case, the data trees aren't working for me. I want "beam objects" with arbitrary properties, such as lists of intersections. Are there ways to do this "easily" in GH without resorting to C#, VB or Python?…
fear that it would be too hard, but I was pleasantly surprised. Not that bad, even for a C# novice. I am attaching the *.cs files for three components:
SerialCreate component creates the serial port instance. This component controls port parameters and opens/closes the port. (It won't close the port, however.) SerialWrite and Read try to interact with the port created by SerialCreate. I can verify that the port opens because it's unavailable to other terminal applications, but if I try to close the port, it won't...it stays open until I restart Rhino. SerialWrite works, because I can see the rx light on my device light up when I enter text in grasshopper. SerialRead does not work. I blue screen with a DPC WATCHDOG VIOLATION.
All in all, not too bad for a day's work. I'll forget the user objects and go for custom components. The question that still remains is that I don't think I'm correctly or efficiently sharing the serial port instance with the other classes. Again, this is just a hack, but I'm happy I'm closer to solving the problem (or so it seems). If anyone has any ideas about how to better go about this, I'd appreciate any suggestions.
Thanks again,

1. COURSE MODULE (20-23 April 2014) - optional
+ type: 3 days intensive course regarding basic knowledge in parametric design (LEVEL 1)
+ software: Rhinoceros & Grasshopper
+ plugins: Kangaroo, Weaver Bird, Lunch box, Ghowl, Geco
+ achievements:
- acquainting to the components & the concept of Generative Design
- understanding the strategies in Algorithmic Design
- how to easily insert simple mathematical equation into the project to gain more control
- how to utilize proper plugins with respect to their nature of the project
- interacting with different analysis platforms such as Ecotect & remote controller
- solving several exercises with different scales( 2D- 3D ) during each phase of the workshop
2. WORKSHOP (23-27 April 2014)
A 5 day Design-Based Research Workshop exploring new techniques in Digital Architecture/Fabrication, with a specific focus on the use of generative systems and parametric modeling as tools for creative expression.
Our ultimate goal is to increasing the efficiency of utilizing digital tools in parallel with geometric performance of the primitive design agent.
+ + CONCEPT
Fashion and Architecture are both based on basic life necessities – clothing and shelter.
However, they are also forms of self-expression – for both creators and consumers.
Both fashion and architecture affect our emotional being in many ways.
The agenda of this workshop is to investigate on the overlap between these two areas of design, art & fashion.
Fashion and architecture express ideas of personal, social and cultural identity, reflecting the concerns of the user and the ambition of the age. Their relationship is a symbiotic one and throughout history, clothing and buildings have echoed each other in form and appearance. This only seems natural as they not only share the primary function of providing shelter and protection for the body, but also because they both create space and volume out of flat, two-dimensional materials.
While they have much in common, they are also intrinsically different – address the human scale, but the proportions, sizes and shapes differ enormously.
+ + + OBJECTIVES
So far, Architects have been using techniques such as folding, bending etc. to create space, structural roofs or different other structural shapes.
The agenda of this workshop goes further with the investigation of algorithmic thinking through generative tools Integrated in design.
The challenge is creating a bridge that connects these two areas of design, architecture and fashion that perform at two opposite scales.
+ + + + TECHNICAL BRIEF
In the early stages physical models and low-tech strategies will be used, allowing the participants to gain a greater understanding of materials, fabrication and assembly methods as well as simple, yet pragmatic structural solutions.
Later in the workshop these strategies will be digitalized and elaborated using software visualizing tools such as Rhinoceros and the algorithmic plug-in Grasshopper.…
he Cordyceps. Maybe some of you find this helpful/useful.
So basically, the Cordyceps is a physical module with 4 knobs and 1 slider. The knobs give an output between 1 and 1000, while the physical slider outputs 0-359. And of course, for this physical module I wrote a plugin to communicate with it. The knobs are intended to be the variables that modifies the design, while the physical slider is intended to be connected to the camera component.
Here I will put up "the recipe" for all to make their own module. You will be able to download the plugin as well.
Please send me a message if you want the 3D-files for the knobs, the box and slider knob. They've been made to directly 3D-print.
Plugin:
https://github.com/zakadjeb/Cordyceps/blob/master/Cordyceps/Cordyce...
Code for Arduino IDE:
https://github.com/zakadjeb/Cordyceps/blob/master/Arduino/_Arduino_...
What you need:
1x - Arduino (Leonardo, UNO or whatever)
4x - Potentiometers
1x - Sliding potentiometer
1x - Breadboard
Bundle of jump wires.
1. So, a potentiometer is a variable resistor, which is basically a component that changes the resistance between the voltage and the ground.
If A is supplied with 5V then B must be connected to Ground. The W will give "read" the resistance, and thus should be placed in Analog input (A0-A5) on the Arduino. The slider potentiometer works the same way.
2. Now connect the 4 pots to each their Analog input. The slider is supposed to be in A4. So to make sure:
A0: Knob1
A1: Knob2
A2: Knob3
A3: Knob4
A4: Slider
3. Now it's time to connect the voltage! Using the breadboard, the voltage can be sent through 1 line, the Ground as well. It should be quite easy to connect them.
4. Now, download the Arduino IDE and copy-paste the code I supplied above. In the IDE, you need to let it know which Arduino you're working with, and which port is should send the script.
5. Almost there. Download the plugin. Open the port you're using through the plugin. Set Start to True and the Cordyceps should be within you.
This recipe will be updated!
Let me know if there are any issues.

the bubble diagram. This algorithm works by a set of attractive and repulsive forces (as in Equation 9) acting recursively on graph vertices, seeks a ‘relax’ situation for a graph, and reaches to a graph drawing. This tool is quite intuitive and shows in real-time bubble diagrams neatly according to the specified areas and the connectivity graph.
Equation 9
Attraction: 〖AF〗_ij=ka ∆x_ij for all linked (i,j)
Repulsion: 〖RF〗_ij=kr /x_ij for all (i,j)
The attraction/repulsion strength inputs are denoted as ka and kr
in the above equations. If some configuration is very messy, you need to have a high repulsion first to untangle it. I have not tried Angel's method but it is very similar to the method we have scripted for this component.
I hope this helps.

st for the quality of the mesh.
Actually, convergence is much more than simply having low residuals. You can have a wrong solution with very low residuals. Usually, it is a combined process of both run time information on residuals and having an idea or expectation of what the simulation results should be. Another way of assessing convergence is if the residual values have been stable (within a very small limit, e.g. 1E-5) for more than a certain number of iterations (e.g. 1000). We are planning to provide run-time residual plots in Butterfly, hopefully soon. These plots can help keeping an eye on the solution.
You could try as a test if you want to switch to a blend of first and second order (by swapping upwind with linearUpwind in the fvSchemes)
.
Concerning mesh quality there are a number of ways, some of which are a bit advanced for this post and for BF's current capabilities. The best way to start is by refining the background mesh (i.e. the blockMesh). You can do that by assigning more cells to the x, y and z directions in the blockMesh component. However, make sure you increase the max global cells. I would suggest you monitor the output of the blockMesh in order to know the total number of cells there. Your max global cells has to be higher than that for SHM to even work. I'd suggest 2x to start with. Ofc all that requires a bit of trial and error depending on the case at hand.
Hope this helps!
Kind regards,

I am no expert in this field; I would have to do research just like you. Maybe someone else on this forum has already done more work in this area, let's see. Or it might be you, the first one :)
This does not look like something completely at reach for someone with not much programming experience, but maybe with some guidance it could be doable.

>>Do you know other libraries that I can use with it?Sorry I would have to search for other libraries just like you.
EDIT: This link has a simple sine wave written from scratch. It might be a good start to mix with the code above and a playground to understand theory.
