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.

2. WORKSHOP (23-27 April 2014)
A 5 day Design-Based Research Workshop exploring new techniques in Digital Architecture/Fabrication, with a specific focus on the use of generative systems and parametric modeling as tools for creative expression.
Our ultimate goal is to increasing the efficiency of utilizing digital tools in parallel with geometric performance of the primitive design agent.
+ + CONCEPT
Fashion and Architecture are both based on basic life necessities – clothing and shelter.
However, they are also forms of self-expression – for both creators and consumers.
Both fashion and architecture affect our emotional being in many ways.
The agenda of this workshop is to investigate on the overlap between these two areas of design, art & fashion.
Fashion and architecture express ideas of personal, social and cultural identity, reflecting the concerns of the user and the ambition of the age. Their relationship is a symbiotic one and throughout history, clothing and buildings have echoed each other in form and appearance. This only seems natural as they not only share the primary function of providing shelter and protection for the body, but also because they both create space and volume out of flat, two-dimensional materials.
While they have much in common, they are also intrinsically different – address the human scale, but the proportions, sizes and shapes differ enormously.
+ + + OBJECTIVES
So far, Architects have been using techniques such as folding, bending etc. to create space, structural roofs or different other structural shapes.
The agenda of this workshop goes further with the investigation of algorithmic thinking through generative tools Integrated in design.
The challenge is creating a bridge that connects these two areas of design, architecture and fashion that perform at two opposite scales.
+ + + + TECHNICAL BRIEF
In the early stages physical models and low-tech strategies will be used, allowing the participants to gain a greater understanding of materials, fabrication and assembly methods as well as simple, yet pragmatic structural solutions.
Later in the workshop these strategies will be digitalized and elaborated using software visualizing tools such as Rhinoceros and the algorithmic plug-in Grasshopper.…
rves/holes. However, the Kangaroo script itself is prone to locking up so it seems like it might take forever. You can even double click stop the timer from the Windows task bar, I hadn't noticed that before:
You have to use that or right click disable the timer since even with the Reset toggle button input set to True the timer itself locks up the script a bit when you are changing things around.
Just setting the min/max numbers both to a desired mesh size gives a uniform mesh:
Oh weird, it's about if the timer is right click set to so small an interval that it gets ahead of Kangaroo! When you see how long each cycle is taking with the Display > Canvas Widgets > Profiler you just set the timer for above that and the interface comes back into being responsive. It only takes a few Kangaroo cycles to do the inflation, so a full second timer interval is even workable.
A finer mesh:
It's funny running it so slow since it overinflates at first, bulging out, before it equilibrates.
You have control over inflation pressure and mesh stiffness, for a variety of effects.
This is a good system once I realized the timer needed to be mellowed out.
What made it work was the fast custom meshing since a normal mesh is awful and MeshMachine wouldn't work with sharp corner holes at all, breaking out of the boundary even if I fixed curves or vertices or did the equivalent with NURBS surfaces instead of a starting mesh.
There is an initiation time for Kangaroo that doesn't show up on its Profiler time that happens even with the timer off.
There are some fine areas that can't inflate with a reasonable mesh setting:
Worth playing with but no match for ArtCAM since it suffers odd delays in between working fast. If I could get better 2D meshes, that were more adaptive it would be better, but MeshMachine is one of the only re-meshers I know and it's broken for even mildly sharp hole features.
Ah, how about a crude mesh that is then subdivided, guaranteeing inner vertices everywhere? Sort of works, but is still too dense. Way too dense to even do anything. The subdivision triangulates the quads, vastly increasing the mesh wire density. Better just to make a finer initial mesh with plenty of quads.…

(1) I have been exporting small sections of a larger model into Maya from Rhino as FBX. In Maya I rotate and scale the models (-90 in X, Scale XYZ 0.001). The Named Views are being saved, but do not have a successful import into the Maya model. They do not appear as in Rhino, and the problem is not solved by scaling or rotating the cameras.
(2) If I try going the other direction, the cameras exported from Maya as FBX are also not aligning with the model in Rhino as they are in Maya.. I will do my best to post some images of the problem and hope you can help.
error !!
This is what the named views look like
here I am trying to the other way with a good view from Maya
strange placement..
This is the best result I can achieve, after I scale the camera by 1000
Any Advice???
Thanks, Robert.

When you run the simualtion you will notice on the batch terminal that Daysim is also being called, so you may want to consider how Daysim uses Radiance files & data.
Regarding your current problem, I think you stumbled onto something weird and interesting.
Interior and exterior readings appear to differ by 40 in the best case scenarios. Even setting the transmittance to 1 yields similar results. I tried changing from cummulative sky to climate sky and got similar values. Changing the test points did nothing either.
I think, (yet I'm too lazy to prove this) that the difference in values stems from diffuse radiation over the sky dome.
If you delete everything except the glass you'll notice that interior values are like 80-90% of the exterior values (this seems like the expected behaviour with a transmittance of 1). So, if we consider that a vertical window, part of an opaque box, is receiving radiation from 25% of a sphere, as you start to inset the interior test points the radiation they receive will be a fraction of the 25%.
Let me try to explain this better...The exterior surface receives radiation from a section of a sphere calculated by 180degrees on the xy plane (let’s call this angle theta) and by 90degrees (let’s call this angle phi) in azimuthal elevation. If you integrate this over spherical coordinates (theta from 0 to pi; phi from 0 to pi/2) you will find that it comes to a quarter of a sphere. By comparison, the interior surface will not integrate theta from 0 to 180degrees,nor phi from 0 to 90degrees, instead it will be the subtended angle from the exterior surface as a function of their separation; the farther in you go the smaller the view of the outside.
If my hypothesis is correct there shouldn't be that much difference since the separation is only 10cms...the subtended angle would be like 170 instead of 180 for theta and 85 instead of 90 for phi...overall if you integrate both spherical areas there should only by a difference of 10%.
In conclusion, I believe the unexpected behaviour stems from the previous subtended angle thing. If direct radiation was the only factor the difference would be the aforementioned 10%, which suggests that an additional source of energy is also affected by this. Perhaps indirect and diffuse radiation from other areas of the sky dome.
I’m definitely intrigued on why this is happening. Please post if you figure it out.

Mauricio

he time to work with it.
the project is about facade strips which turns along height. the top angle is
parallel to the facade and the bottom is max. 90 degrees twisted, but the strips
should turn diffrently to achieve more dinamic look.
first i have tried to achieve this by calculating distance between the rotation angle from points of the grid and a single point.
then i have tried to ad some more effecting points and used the distance to the divided surface (the circles are just to control the area of effection):
i manually lofted it.
the result is a bit annoying becouse the points that effect the angle are always visible:
i have triend to solve this by drawing a line and divided it to recieve points along the bottom of the geometry. the result is not working properly:
Anyway,
there must be a better/smoother way to achieve this. i would like to effect the twist of the surfaces by distance to a spline, but im just lost. can you help me please?
the problems im encountering:
0- distance spline to grid to effect the angle
1- list of x/y coordinates and angle of rotation for each point of the grid
2- export points to excel
3- lofting lines in one direction only (x1, x2, x3...)
4- reduce the list data to 2 decimal (0,00)
5- maybe angle from radian to degrees
thx…

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
