Data matching is a problem without a clean solution. It occurs when a component has access to differently sized inputs. Imagine a component which creates line segments between points. It will have…
olution emerging in the architectural industry world-wide, the Department of Architecture at The University of Hong Kong will host a two week intensive summer program named Digital Practice.
Led by professors from The University of Hong Kong, as well as invited practitioners with expertise in practice of cutting edge digital techniques, the program offers participants opportunities to experience applications of computational tools during different stages of an architectural project, i.e. concept design, form finding and optimization, delivery, management and communication of design information under the team-based working environment. By learning advanced computational techniques through case studies in the context of Hong Kong, participants are expected to go beyond the conventional perception of technology, considering users and tools as a feedback-based entity instead of a dichotomy. The program, which is taught in English, includes a series of evening lectures related delivered by teaching staff and invited local architects.…

So there is multiple file
1. This is the ghx made by Yasser for who ever needs it (Yasser if you want me to remove it i can)
2. This is the grasshopper that i made the longest lines represent the step i want to make disappear (cf the mind_mapping.jpg which shows what are the actions done)
3. This is the final result i would like to achieve (already done grasshopper + manualy but out of curiosity i would like to make it all with grasshopper !)
Thx all in advance :)…

The HBZ stadium was developed with Rhino/Grasshopper and Revit.
Grasshopper was utilised from Concept level through to the production of Construction drawings.
The stadium's unique parasol roof passively provides the maximum amount of shade to create playable conditions for a desert stadium, while not obstructing grass growth.
The 25,000 seat bowl was modelled and optimised through 3d sightline calculations, to make the bowl as tight and efficient as possible while guaranteeing the best possible C-Values.
The diagrid facade, is made up of palm-inspired panels, creating shade, allowing air flow through the stadium. Panels are angled up to allow views out from key locations.
The 640 panels were carefully rationalised for construction. From an original set-out of 320 unique forms, the panels were reduced to 82 sizes without any noticeable aesthetic impact.
The full implementation of a parametric workflow in a BIM environment meant the stadium was delivered on an unprecedented fast track 18 month Design & Build.…

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.

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

it we thought our stands will be made with a fixed depth (80 or 90 cm) and incremental heights like 30-32-34-36...cm, and that is the list you have to supply.
The script will iterate over the different possible measures until it finds the smallest one that complies with your desired C value, but it wont be the exact, just the best approximation within your list.
2. Changing this also depends on the combinations of riser height and depth you provide, if you enter 1m and 1m in both lists you will get an 45º slope.
Anyway, getting a fixed-c value script would be easier (much easier than what is already there) but IMO it wouldn't have a direct application in real stadiums unless you are ready to make each stand different from the rest, discarding any pre-cast solution.
Hope this helps.

raries folder, seems that you need plankton.gha.
Unlock, place in folder, restart rhino+gh...
That's all.
To use it... in a basic way:
Input 0. Plug geometry.
Input 1. Set target resolution, actually it refers to the mesh edge length.
Optional input 2 and 3. Sets anchors (as points or curves) for the remeshing not escape of these parts.
Input penultimate. Number of iterations. Here are two ways, the living form, you set a low value (as 5 or 10) of iterations and plug in a timer component (that allows you to see the remesh process); or just add the total number of iterations (I generally use 80, but its relative).
The last input, set false to turn it on, true to turn it off.
For advanced configuration, trial and error, or see the code on Pikers's github.…
