This definition is designed for an outdoor study (an indoor example will follow shortly). It also includes a hopefully more user friendly UI that allows the user to set all the necessary inputs for the simulation and run the case without using the actual GH definition.
To use this example to its full extent, along with Butterfly (details on installations can be found here https://github.com/mostaphaRoudsari/Butterfly/wiki/Getting-Started-with-butterfly) you will also need the HumanUI tools (http://www.food4rhino.com/project/human-ui?ufh). However, HUI isn't necessary if you are only interested in the BF part of the definition which will still run.
Butterfly, and the example itself, is still a work in progress. I hope it can inspire people to get involved, test things out, and help it improve!
Kind regards,
Theodore.
P.S.: Add the path of the attached butterfly logo's location in your computer in the definition for a more buggy feeling :)

by arch.tualize and AWARE in partnership with the Städelschule Architecture Class (SAC), Frankfurt and will be held at the campus of SAC from 21 July – 1 August 2014. The lab engages students, architects, designers and game developers with four techniques of prototyping: designer-informed, analytics-driven, crowd-operated and sensor-actuated. Participants learn to use digital and parametric design tools and engage with feedback collected from simulation algorithms, online users and real-world sensors. The acquired knowledge will be applied to designing interactive prototypes ultimately exhibited at an open public exhibition at the Städelschule

stepper motors with an arduino DUE ( 84 MHz clock) so would be faster than an UNO (16 MHz).
The problem : The DUE is selectionned, detected and I can open the port in grasshopper, but when I try to send any mouvement with the stepper component.. isn't moving at all.
Also when I try to read the serial monitor with the generic serial read component is also not reading anything coming from the due card (I tried the programming port and the USB communon port from the DUE).
To now : Sending mouvement with the Accel Stepper library directly with the Arduino IDE works, Wich means that the problem is directly coming from the communication between the Firefly's Grasshopper component and the arduino Due
The due : www.arduino.cc/en/Main/arduinoBoardDueThanks for your time :-)…
starting mesh. The geometry of the lines is then modified, through the formfinding routine.
In my second vb component, I need to build an array with 4 columns. Each row represent one face of the mesh (row 0 for face 0, row1 for face 1, ...) and each column represent the number of the edge element. If ABCD is the quad face, column 0 is the number of the edge AB, column 1 is BC, column 2 is CD and column 3 is DA.
So to build this array, I extract the edges of each face with FaceB component then Explode component, and I build the array by comparing each line coming from this to each line coming from MEdges component, with a 2 level nested loop. Here is where I am looking for an efficient way to compare 2 lines...
Is there an easier and faster way to build this array ?…

But with my script, I canot align the center of gravity with the center of buoyancy longitudinally.
What I would like to do is to have 3 inputs:
- Heel angle (Degrees)
- Displacement (Tons)
- Center of gravity position of the ship (X, Y, Z)
And the script acts on the hull depth (like now) AND on the trim angle, so the GC and BC can be aliged longitudinally.
Anobody has an idea ?

Can anyone help me?…
een them to be adiabatic (at first. See later on for an alternative).
The whole process is fine/clear up to the solveAdjacencies: The walls are defined as "outdoors" and "surface" for the boundary conditions. So far so good.
Now i get to the HB_makeAdiabaticByType, and some issues appear (See A in the file).
Setting the interiorWalls to True doesn't change the condition from"surface" to "adiabatic" (A1 in file).
Setting the walls set both internal and external, to adiabatic (A2 in file). Is this supposed to work like this? Why the just the internal doesn't make the change?
In addition to this i'll appreciate your advice in the following. Let's say that i want the internal walls to be divided in 2 parts each. One should be adiabatic and the other "air wall". How do you recommend to do this? Is the modeling in the file correct, or i must do surface by surface?Or using the Decompose Honeybee Zone ...?
How can i retain the air walls and still use the makeAdiabaticByType component?
Thanks for your help!!

per space. In the upper right corner you draw another dot, and you write "1, 1" next to it. You now have 2 points defined in paper space (uv space).
Ok, lay down the pencil and pick up the paper. You'll notice that the two points have just moved through world-space. They were very close to the desk, but now they are hovering above it. The coordinates you wrote down on the paper or the other hand are still valid.
No matter what you do to this piece of paper; crumple it, fold it, take it on a plane to South Africa, those two points remain fixed in paper space.
A surface is always a rectangle in Rhino. It may be deformed, it may have holes cut into it, but in the end it's always a rectangle, just like your piece of paper. UV coordinates are points that are defined in Surface UV space. They consist of only two numbers, because a surface has no thickness. At any point in time, you can translate these UV points into World XYZ points using what is called a surface evaluator. Where these XYZ points end up depends entirely on the *shape*, *size* and *location* of the surface.

Surface uv-space (and Curve t-space) are vital when dealing with nurbs geometry. If you do not understand the concept of parameter space, you will have a lot of problems because many components in Grasshopper use these coordinates.

, and made the below definition to try it out. (lots of components to draw a line, but I'm just trying to understand the equation)
I had been searching for advice on some geometry topics worth exploring for a class, and now I'm in the class and the teacher wants me to start by learning about splines in general (not nurbs). I just spent the day learning linear spline interpolation, then quadratic, then cubic. I didn't try working them by hand yet, but I'm getting the concepts. It seems cubic is the lowest degree where you can get C2 continuity, which makes it smooth. I read over parameterization and how that simplifies the number of equations. I read about space curves, and then the differences between Hermite, Catmull-Rom, and Cardinal spline, but then got tired and had a cocktail.
So I guess I'm looking for any direction or advice on how to understand parametric curves in 3d space, and how they can be defined (splines or otherwise). Thanks!!!
