se (like in nature). the length of the sticks shall be controlled by the brightnessvalues of a picture. so the bend have to be controlled, too.
now we have several problems:
1. how can i map a hexgrid on a curved surface?
2. how can i adapt the grid to the dimensions of the surface (no overlap, no gaps to the bound)?
3. important
: to create the curved sticks, we use points on a line and we move some of them and then we want to connect the right points via interpolated curve to create each curved stick. now the problem is that the points have to been filtered in the right way. we know that we have to filter each list of points to the index values of the points. the number of index values is the number of hexgrid rows, so there are a lot and we can't use a list item for each one. it could be hundreds.
is there any opportunity to sort a list after the index values (first every index=0, then index=1, ...n)?
or is there any component which does a group of operations for n-times (n is the flexible number of index values) ?
4. how can i control the length and bend of the sticks via the brightnessvalues of a picture?
please help us. thanks.
german version:
In einem hexagonalen Raster soll sich senkrecht zu Oberfläche ein Stab im Mittelpunkt jedes Sechsecks befinden. Dieser soll sich ab einem gewissen (festgelegten) Punkt Richtung Boden biegen. Zusätzlich wird die Länge des Stabes zum Beispiel durch die Information eines Bildes gesteuert, so dass auch die Biegung, je nach Länge, geregelt werden muss.
Wir haben ein Hexagonales Grid (HexGrid) erzeugt und in jeden Mittelpunkt eine Linie senkrecht zum Grid erzeugt, aus der wir uns Punkte mit CurvePoint ausgeben lassen. Der letzte ist verschoben, um eine Biegung zu simulieren. Um die Punkte zu einer interpolierten Kurve zu verbinden, müssen sie nach dem Index sortiert werden. Gibt es eine andere Möglichkeit, als jeden einzelnen Indexwert über ein ListItem herauszufiltern (Da die Rasterung flexibel einstellbar sein soll, entstehen n Indexwerte)? Oder kann man eine Liste nach den Indexwerten, also nicht nach den Punkten, sortieren?
Und wie kann man über Bildhelligkeitswerte die Länge der Stäbe und damit auch die Biegung steuern (ein kurzer Stab biegt sich weniger als ein langer Stab)?
Gibt es die Möglichkeit ein hexagonales Raster auf eine gekrümmte Fläche zu mappen?
Und wie passt man ein solches Raster (HexGrid) in eine Fläche mit definierten Maßen ein, ohne dass das Raster an den Rändern übersteht oder die Fläche nicht vollkommen ausfüllt?

es has guided me in a - what I once thought - specific path within architecture, but recent discoveries (like the Grasshopper-community etc.) have learned me that the field of digital and parametric architecture is so-to-speak alive and kicking. This is also the main subject I would like to write my thesis about. It is however mainly the subject and defining its boundaries – what do I really want to explore and research? – which is the most difficult factor at this time.
A concrete idea is non-existant, and my current visions will probably be redirected when I have a first meeting with the promotors in February. Moreover there is the knowledge that it is impossible to make a thesis at the institute in Antwerp on no matter what subject in the world of digital architecture. Understandably too, it’s a small world and does not always result in realised projects, but in impressive imagery. At this moment however, I am thinking of two possible research fields to focus on.
In a first option the focus might lie on how digital design tools can be used to bring a certain aspect of interactivity to building facades. Such interactivity can occur both in the design phase and throughout the use of the building. The first scenario, in which the interactivity occurs when designing, I would focus on how the designer can shape a building’s outer perspective in function of environmental parameters: obstacles, elements that block sunlight from entering the building, visually important landmarks, etc. It should be noted however that focus will mostly lie on the design element, and less on the energy-efficiency and sustainability. Tools that will be researched would include Grasshopper, Rhino Scripting, Processing and ParaCloud.
A second possible approach could be categorized under both Swarm Intelligence and Generative Design and might study how the aforementioned digital techniques might be implemented in the new urbanism. We notably see more (innovative) interventions in which the design and planning is heavily influenced by movement patterns and morphogenetic parameters and functions. Based on the outcome of these scripted techniques, designers tend to work towards a proposal which answers a certain urbanistic issue.
All additional insights, guidelines, tips, comments are more than welcome in order to help me define the scope of my thesis subject. I must admit I am pretty new to this digital design world (it is not actively promoted at my home university, but it is promoted at the university where I am studying for one year now) and thus have limited experience at the time of writing.
Please also feel free to check out the blog post concerning this topic, which is a little more elaborate: http://nielswouters.be/thesis-digital-design-english/

mplex the models are. If we are running multi-room E+ studies, that will take far longer to calculate.
Rhino/Grasshopper = <1%
Generating Radiance .ill files = 88%
Processing .ill files into DA, etc. = ~2%
E+ = 10%
Parallelizing Grasshopper:
My first instinct is to avoid this problem by running GH on one computer only. Creating the batch files is very fast. The trick will be sending the radiance and E+ batch files to multiple computers. Perhaps a “round-robin” approach could send each iteration to another node on the network until all iterations are assigned. I have no idea how to do that but hope that it is something that can be executed within grasshopper, perhaps a custom code module. I think GH can set a directory for Radiance and E+ to save all final files to. We can set this to a local server location so all runs output to the same location. It will likely run slower than it would on the C:drive, but those losses are acceptable if we can get parallelization to work.
I’m concerned about post-processing of the Radiance/E+ runs. For starters, Honeybee calculates DA after it runs the .ill files. This doesn’t take very long, but it is a separate process that is not included in the original Radiance batch file. Any other data manipulation we intend to automatically run in GH will be left out of the batch file as well. Consolidating the results into a format that Design Explorer or Pollination can read also takes a bit of post-processing. So, it seems to me that we may want to split up the GH automation as follows:
Initiate
Parametrically generate geometry
Assign input values, material, etc.
Generate radiance/ E+ batch files for all iterations
Calculate
Calc separate runs of Radiance/E+ in parallel via network clusters. Each run will be a unique iteration.
Save all temp files to single server location on server
Post Processing
Run a GH script from a single computer. Translate .ill files or .idf files into custom metrics or graphics (DA, ASE, %shade down, net solar gain, etc.)
Collect final data in single location (excel document) to be read by Design Explorer or Pollination.
The above workflow avoids having to parallelize GH. The consequence is that we can’t parallelize any post-processing routines. This may be easier to implement in the short term, but long term we should try to parallelize everything.
Parallelizing EnergyPlus/Radiance:
I agree that the best way to enable large numbers of iterations is to set up multiple unique runs of radiance and E+ on separate computers. I don’t see the incentive to split individual runs between multiple processors because the modular nature of the iterative parametric models does this for us. Multiple unique runs will simplify the post-processing as well.
It seems that the advantages of optimizing matrix based calculations (3-5 phase methods) are most beneficial when iterations are run in series. Is it possible for multiple iterations running on different CPUs to reference the same matrices stored in a common location? Will that enable parallel computation to also benefit from reusing pre-calculated information?
Clustering computers and GPU based calculations:
Clustering unused computers seems like a natural next step for us. Our IT guru told me that we need come kind of software to make this happen, but that he didn’t know what that would be. Do you know what Penn State uses? You mentioned it is a text-only Linux based system. Can you please elaborate so I can explain to our IT department?
Accelerad is a very exciting development, especially for rpict and annual glare analysis. I’m concerned that the high quality GPU’s required might limit our ability to implement it on a large scale within our office. Does it still work well on standard GPU’s? The computer cluster method can tap into resources we already have, which is a big advantage. Our current workflow uses image-based calcs sparingly, because grid-based simulations gather the critical information much faster. The major exception is glare. Accelerad would enable luminance-based glare metrics, especially annual glare metrics, to be more feasible within fast-paced projects. All of that is a good thing.
So, both clusters and GPU-based calcs are great steps forward. Combining both methods would be amazing, especially if it is further optimized by the computational methods you are working on.
Moving forward, I think I need to explore if/how GH can send iterations across a cluster network of some kind and see what it will take to implement Accelerad. I assume some custom scripting will be necessary.…
ou will see all of the available components on a ribbon at once so there is no need to keep clicking drop down menus.
It's all about discoverability with GH. What if you're a beginner and don't know about the Create Facility (dbl click canvas) how can you find Extr?
Even if you hover over every component or use the drop down lists you will not see the name Extr appear anywhere.
Sure it makes sense that Extr is short for Extrude but it's also the Nick Name of Extrude to Point component
So you can easily miss the fact that one has a Distance Input verses a Point Input.
I think I made the move to Icons around about the move from version 0.5 to 0.6, possibly before. I initially thought that I would go back to text because I loved the mono chromatic look of the text but I soon realised that Icons were the way forward. The greatest benefit is speed. You don't need to digest and decipher every component (which is written 90 degrees to the norm).
I'm not saying you should move to Icons forthwith but at least consider that once you have a better knowledge and understanding of GH, Icons will set you free.
My top ten tips that I would highly recommend to anyone wanting to better themselves with GH.
1) Turn on Draw Icons
2) Turn on Draw Fancy Wires
3) Turn on Obscure Components
4) Use the Create Facility like a Command Line eg "Slider=-1<0.75<2" or "Shiftlist=-1"
5) Use Component Aliases to customise your use of the Create Facility eg giving the Point XYZ component an alias of XYZ will bring it up as the first option on the Create Facility as opposed to the other possibilities.
6) Try to answer other people's questions even if it's not relevant to your own area. By looking into solving a problem outside of your comfort zone and then posting your results it is very rewarding but it also lets you see the other approaches that get posted in a new light.
7) Take the time to understand Data/Path structures.
8) Buy a second monitor - There is nothing that can compare to real estate when working in Grasshopper.
9) Read Rajaa Issa's Essential Mathematics
10) Pick a panel in a tab on the ribbon and get to know every component inside and out and then move on. Start with the Sets Tab > List Panel…

onents (radiation, sunlight-hours and view analysis) which let you study the effect of the orientation of your building and the analysis result. When you come to a question similar to "what is the orientation that the building receives the most/least amount of radiation?" is probably the right time to use this component.
HOW?
I'll try to explain the steps using a simple example. Here is my design geometries. The building in the center is the building to be designed and the rest of the buildings are context. I want to see the effect of orientation on the amount of the radiation on the test building surfaces from the start of Oct. to the end of Feb. for Chicago.
First I need to set up the normal radiation analysis and run it for the building as it is right now. [I'm not going to explain how you can set up this since you can find it in the sample file (Download the sample file from here)]
Now I need to set up the parameters for orientation study using orientationStudyPar component. You can find it under the Extra tab:
At minimum I need to input the divisionAngle, and the totalAngle and set runTheStudy to True. In this case I put 45 for divisionAngle and 180 for the totalAngle which means I want the study to be run for angles 0, 45, 90, 135 and 180.
[Note1: The divisionAngle should be divisible by totalAngle.]
[Note 2: If you don't provide any point for the basePoint, the component will use the center of the geometry as the center of the rotation.]
[Note 3: You can also rotate the context with the geometry! Normally you don't have the chance to change the context to make your design work but if you got lucky the rotateContext input is for you! Set it to True. The default is set to False.]
You're all set for the orientation study, just connect the orientationStudyPar output to OrientationStudyP input in the component and wait for the result!
The component will run the study for all the orientations and preview the latest geometry. To see the result just grab a quick graph and connect it to totalRadiation. As you can see in the graph 135 is the orientation that I receive the maximum radiation. Dang!
If you want to see all the result geometries set bakeIt to True, and the result will be baked under LadyBug> RadaitionStudy>[projectname]> . The layer name starts with a number which is the totalRadiation.
