eaningful. Humans must interact with it. Information arises when humans examine the data. Knowledge is created when information is transformed through human social interactions.”

The space in which we live can be monitored in many aspects and appears to be to be a gradient of data in continuous evolution and change. One of the major advantages of parametric tools is to be able to inform the design processes with accurate, specific and variable, in space and time, data streams .
DATA BODIES is a Grasshopper workshop that will focus on how its nature as an information processor and how it can be (ab)used in order to manipulate data, streaming inputs from various sources and use datafeeds to inform geometry or data structures from the very simple up to more complex ones. The aim is to give an understanding of information and data articultion as already a spatial and architectural operation; results may range from pure data communication protocols, dataviz or data-driven geometries depending on the skill levels and aspirations of each participant. The brief is also open to the suggestions and opportunities that may rise during the workflow.

them can be addressed before winter.
Bugs:
. Vector preview is great, but it doesn't refresh (clear) when you disconnect components. You must delete the component or reconnect to refresh the vector previews.
. When passing values through a note pad, note pad fails to update continuously. Moving the notepad updates the display.
. Cannot pass a notepad integer into an fx1
. Point preview in RH5 appears as large red blocks, not as red crosses. (This is an old bug, may have been fixed with RH5 update in the meantime.)
. After adjusting Graph in dialog box, graph appears to be a solid grey object until moved.
. After copying and pasting, a lot of components are broken, return nulls. Requires reconnect to recompute (haven't had this problem in a while, will see if I can find a file that recreates it)
. BIG ONE: Loading a graph mapper with a file not found creates broken file... graph mapper disappears off canvas and the output wire appears turns orange and appears to be coming from the 0,0 pixel of the canvas. This happens any time you try to port a .ghx file to another system with different drive letters/paths, etc.
Wish list:
Mass addition for vectors
Interactive domain control for Image Sampler (like with Gradient Mapper)
Allow Addition Component to handle String values (A + B = AB)
BIG ONE: Request Override for Icon display for Parameters, Wireless receiver, and script components if you change the name
BIG ONE: Add new behavior for Stream Filter and Stream Gate: Allow multiple index numbers. The Index number picks the value/object in the corresponding index position in the selected list.
For instance:
List 0: A, B, C, D, E
List 1: 1, 2, 3, 4, 5
List 2: .1, .2, .3, .4, .5
Index Stream: 0, 2, 2, 1, 1, 2, 1, 0, 1
Results: A, .2, .3, 4, 5 (This is new behaviour and more useful than Weaving)
I have attached a GHX that includes VB components that do this, but it would be better to have GH components with I/O manager options and data matching behavior, etc.

curves A and B.
For each point pA on curve A,
you need the corresponding tangent vector tA on curve A, and the lists of "cone" vectors pB(j)-pA and tangent vectors tB(j) on curve B. so you have three vectors tA, tB(j) and AB(j)
these three vectors define a parallelogram thas varies along j
3d determinant of the three vectors above gives you the volume of this parallelogram. When 3dDet = 0 then it means it's flat, the vectors are coplanar. Thats what we're looking for.
So you just need to plot the curve 3Ddet = f(pB) , still for each point on A
'pB is the parameter here'
graphically solve these cuves to find the zeros and you feed back the resulting parameter in curve B. draw te line, done.
You can manage double solutions or cusps directly on the plot by using clostest point and >= conditions to kill unwanted results.
I do it twice, from crv A to crrv B and from B to A to make sure I catch start and end generatrices each time.
The videos you posted are interesting. I don't understand how it works with just 2 slider to tune the curves.
…
as passing this extra check and because of that it was running faster. It doesn't mean that the first analysis is totally wrong as it depends on the analysis case and should be checked and optimized before running the final analysis.
You can read more about radiance parameters here (http://radsite.lbl.gov/radiance/refer/Notes/rpict_options.html), and here (http://radiance-online.org/community/workshops/2011-berkeley-ca/pre...). Since you have a light-shelf I suggest you to add to the number of ambient bounces (ab).
Now back to your wish to have the analysis run faster you can comment the line hb_writeRADAUX.checkInputParametersForGridBasedAnalysis() inside Honeybee_runDaylightSimulation and it won't overwrite the initial values but make sure that you run a number of test cases and compare the results between the runs.
Back to your definition, it looks good to me. You could have saved yourself some time by using MassToZone component and then just adding the ceiling separately but there's nothing wrong with your approach.
The main place in the definition that can change is how you're generating the vertical fins. I imagine you can use a single set of components to generate every group of the fins but again your definition will work.
I updated your file to the latest version, which means you also need to update Honeybee and Ladybug in case you're looking to modify the file.
Hope it helps,

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?
The alternative approach in my mind as a GH beginner is as follows. But I am not sure whether it is doable. Again, your comments will be greatly appreciated.
Since all my room/window/shades dimension are controlled by number sliders, I am thinking whether a component from GH will trigger these number sliders (not necessary to be all of them but one by one) automatically. If this is possible, I can do "data recorder" to record outputs from ASE and sDA. Eventually I will have a database of the input parameters and sDA/ASE results.
Does it make sense? Is there a component which can trigger number slider output at certain step?
Many thank!

Il workshop avanzato ECOLOGIC PATTERNS affronta l’impiego di strategie parametriche all’interno del processo progettuale, approfondendo l’utilizzo di Grasshopper in sinergia con plug-in, software di analisi ambientale e simulazione fisica. Obiettivo fondamentale è la generazione della forma come risultato di tecniche di form-finding e di input ambientali (solari, termici e acustici). Verranno acquisiti nuovi strumenti operativi e di simulazione al fine di costruire modelli parametrici ottimizzati in grado di adattarsi a diverse condizioni di contesto.

ort and export from the images below and also from the HELP file of DB in attachments (Page 71: Importing Geometric Data; Page 78-80: Import 3 - D CAD Data). In their HELP file, they mention about "import geometric data".
However, regarding the input of schedules, loads, constructions and etc., DB normally uses "Component " and "Template" (Page 29: Templates And Components; Page 591: Templates; Page 533: Components). "Templates" are databases of typical generic data, including Activity templates, Construction templates, Glazing templates, Facade templates, HVAC templates, Location Templates, and etc. "Component " are databases of individual data items (e.g. a construction type, material, window pane).
Both "Component " and "Template" are allowed to be imported and exported by using "Import / Export library data" command (.ddf format - DB Database File; Page 734: Import Components/Templates, Export Components/Templates). DB also allows us to build up our own libraries of templates and components (Page 731: Library Management; Page 733: Template Library Management).
In order to import both geometric information and other information related to schedules, loads, constructions and etc. from GH to BD, we supposed the following two ways:
1. GH(HB+GB) --> gbXML (both geometric and "Component " and "Template" information) --> DB
This is the way we most prefer. We did see information related to schedules, loads, constructions encoded in the gbXML file generated by GB, but still do not know the reason why DB did not take this information (I also mentioned this in Q6 within the gh file). We assume this might because the gbXML file we create encodes the schedules based on a different template / schema than the one DB expects. We also post this question to the DB forum for help.
(http://www.designbuilder.co.uk/component/option,com_forum/Itemid,25/page,viewtopic/p,13755/#13755)
2. GH(HB+GB) --> gbXML (geometric information only) + .ddf ("Component " and "Template" information only) --> DB
If the first way doesn't work and DB only takes geometric information from the gbXML, then we might think of the other way - generating the .ddf files from GH(HB+GB) to pass the schedule, load and construction information to DB.
I was wondering if it is feasible for HB and GB to have this function? And what is your suggestion to achieve this?
In addition, we notice that DB can export XML files (not gbXML), so we are trying to figure out if DB also accepts / reads the XML file. If so, we might be able to convert the gbXML (with both geometric and schedule information) to XML. What do you think about that?
Thank you again for all your help!
Best,
Ding
