the space that you are designing and your design intent. Just think about an atrium vs a museum. And now think of the atrium in two different climate zones. As a [lighting] designer you make the decision on how do you want the space to be, how the climate is and then try to take advantage of skylight and/or direct sunlight to achieve your design goals.
2. Yes. There is a watchTheSky component next to sky types which let you visualize the sky. There is also an example file that you can check.
3. This one again depends on your model. For your model I would suggest a minimum number of 4 for your final analysis. -ab is only one of the parameters. Check this slides by John Mardaljevic if you want to have a better understanding of radiance parameters and their effect on the results.
I also added the link to "Tutorial on the Use of Daysim Simulations for Sustainable Design" by Christoph Reinhart to teaching materials. I encourage you to at least read chapters 1 and 2 of the tutorial. Check pages 25 and 27 have two examples about selecting the parameters.
Great questions. Keep them coming.

evel in which each final branch contains a list of one number from each list in all its variations with the other two lists.
12
AB
xy
Becomes eight possible combinations:
1Ax
1Ay
1Bx
1By
2Ax
2Ay
2Bx
2By
Either I could immediately break into 8 branches or branch twice from 2 items to 4 items then from those 4 items to 8 final items. I keep trying grafting with all manner of tree components and *never* obtain a simple dual branching fractal tree structure. I barely even need a tree actually, but I'd prefer each final branch to contain a list I can pull each final value individual value out of rather than dealing with string extraction. This is all to eventually plug all these variations into a parametric mesh model that now uses three sliders, and Python script also to bake them all as OBJ files.
Crucially I also need to obtain the numbers to use as part of my multiply exported OBJ files. I can so far only get a single range to export as a series of OBJ files automatically but not the whole three list array of them.

ace when I start running Galapagos/Octopus (below is "room orientation optimization" shared at http://hydrashare.github.io/hydra/viewer?owner=mostaphaRoudsari&fork=hydra_1&id=Room_Orientation_Optimization&slide=0&scale=1&offset=0,0) It may take quite some time to see some results. That's fine for the above simulation. But my real challenge is, when I am going to optimize room dimension with respect to ASE and sDA calculations, either Galapagos or Octopus goes wildly and never come up with a solution. I believe the time-consuming calculation, especially sDA with higher -ab numbers, trigger the lag a lot? Any suggestion/trick to improve it?
Most importantly, based on your experience, for example to optimize window/exterior shades sizes and achieve ASE<10% and sDA>55% (LEED v.4 requirements), Octopus (due to its capacity of multiple objectives) is the only choice? Any other approaches within grasshopper?
Many thank!

connected hyperspace where architecture can be fluid, flexible and vivid, yet the aspect of materiality requires more attention.
Action-designed structures begin to move beyond the utopian proposals of the 20th century’s manifestos and hold a place in the world of realized designs. The AA Athens Visiting School aims to bring users closer to the built environment while revisiting habits of designing, building and experiencing space through materiality. Understanding materiality and form as a ‘unified whole’, the programme integrates manufacturing techniques through the experimentation fabrication of prototypes at a 1:1 scale.
Prominent Features of the workshop/ skills developed
Participants become part of an active learning environment where the large tutor to student ratio allows for personalized tutorials and debates.
The toolset of the Athens VS includes but is not limited to Processing and Grasshopper for Rhinoceros, as well as design analysis software.
Participants gain hands-on experience on digital fabrication.
Design seminars and a series of lectures support the key objectives of the programme, disseminating fundamental computational techniques, relevant critical thinking, theoretical understanding and professional awareness.

ram.com/Helicoid.html.
To be more precise, I'm not quite clear how to apply this equation to the helicoid and integrate it into my code:
where corresponds to a helicoid and to a catenoid.
I've made some attempts not worth to be shown here. Maybe somebody can help me with a pseudocode or a simple description how to start solving this classic geometric transformation.
Thanks, Sebastian

ructural member. It can only be used as a Veneer / Cladding. You may observe from my sketch that structural member is only a timber frame. Hence we do not need to have a valid bond as long as the brick veneer is tied together with each other and to the timber structural frame behind.
Nevertheless, though i understood the components used in the definition, i only partially understood the logic behind your definition i.e. only until 'Divide Dist' and Extracting the points. After that I did not understand the logic behind using
a) Extracting 40 random values and than using those values as input for Seed to extract another set of 40 random values.
b) Extracting list length, subtracting with random values created in (a) above and then dividing with number 3.
c) Duplicating the Datas
d) The most perplexing is using above logic (a,b,c) to to extract number of branches (number-40) by using Tree Statistics. If number 40 is the input we required for 3rd Random component Why couldn't we connect the List Lenght to Pramviewer and extract the number of branches (40) and connect the output to the Random Component?
e) Finally i did understand the logic behind creating 2 Vector to create the bricks. But i did not understand the addition following the vector.
f) Why do you use the function 'simplify'? - what does it do? I know it simplifies the data tree, but what does simplifying a a data tree do to the entire definition?
Hannes, i know this is quite comprehensive list of doubt, but your help is and will be always appreciated.

ur setup. Can you say what sensor you are using? Are you using an Arduino to write this ascii information to the serial port? If so, there may be some formatting code for the string that you'll need to do to get the Read component to function properly. I see that you were able to open the port and Start reading... so my first thought is that the data is formatted correctly....
All of the read components look for a specific character (in this case two characters) to indicate when it has reached the end of the line being read and should spit out the data. In this case, Firefly uses the Carriage Return (\r) and Line Feed (\n) to know when it has reached the end of the line. In arduino, these are automatically added to any line if you use the Serial.println("blah, blah, blah"); command. Notice, this is different from the Serial.print("nothing to see here"); command. This doesn't mean that you can't still use the regular print command... it's just you need to use the println command to indicate when you've reached the end of the line. Let's take a look at a simple example.
void setup() { Serial.begin(9600);}void loop() { int sensorValue = analogRead(A0); Serial.print("The value of the sensor is: "); Serial.println(sensorValue);
delay(20); // important to wait some small time so you aren't sending just a ton of info over to GH which will cause it to crash :(
}
The first print statement prints a string to the serial port... and the next one adds the current sensor value... and THEN adds the carriage return and line feed to start a new line. The nice thing about using these together is that you can concatenate any type of data you want. If you were to upload this sketch, you should see a sentence being printed to the serial port that says "The value of the sensor is: 512". I made up the number, but you get the idea. Notice, I also had to include a delay function. You don't always need this (there are other ways to go about this) but the important thing to note is that the loop cycle on the Arduino can run really fast. I mean... really fast. So, you wont want to send so much data over to GH, because this could flood the string buffer in the Read component and cause it to crash (eventually). It's a good idea to add some small time interval just to slow it down a bit. I should say that I've optimized the refresh rate in the next release so it's significantly faster... so hopefully this wont be as big of a problem... but hopefully that helps some.
Now... Why are you writing data to a sensor? Sensors by default are considered inputs... so I'm quite confused as to why you would want to send data back (if you are... then you need some way to handle the string data being sent from GH... this is the whole reason we built the Firefly firmata... it sets up the two-way protocol so you don't have to deal with all of that mess... If you're going to read and write, you're better off just uploading the firmata and using the Uno Read and Write components). Also, I'm not very familiar with the Hyperterm or Advanced Serial Port Terminal... but I will say that could get COM conflicts if you're trying to open the port with different tools. Anyway, I hope some of this helps you get up and running.
Cheers,
Andy

phere with the maximum number of triangles but not much than a defined threshold.
I scaled that mesh just to fit Rhino grid, but it is not mandatory. What is useful, is to scale not uniformly the mesh (Scale NU). It could be done after cellular modifier applied or before or before and after. The 3 options are possible in the script. If you don’t need them just put 1 in scale sliders.
Ellipsoid mesh is the populated with points, I put 2 independents populations to randomize a bit further. For each vertices of the mesh the closest distance from the populated points is calculated.
Here is an illustration in color of this distance.
This distance is then used to calculate a bump. If domain for bump is beginning with negatives values to 0, it carves the mesh. Instead it bumps/inflates it.
Some images to illustrate the difference with populating 100 points with one or two populations.
Here some images to illustrate the application of scale before carving or after.
Next phase apply noise. At the moment I don't find it good.…
