bursts of calcium which interacts with a photoprotein to create flashes of light.
In the Pacific Canada Pavilion gallery at the Vancouver Aquarium, the public can excite origami jellies into creating beautiful patterns of colour and light using a touch screen controller.
When left alone, free from human intervention, the origami jellies instinctively react to each other. Random, generative displays of drifting coloured glow are triggered, not unlike jellies in their natural environment.
Jelly Swarm overhangs the gallery space. The soft, coloured light emitted by the jellies reflects on the aluminum surface. Viewed from below, the visual effect evokes looking up to the ocean's surface from undersea.
The installation features 94 origami jellies, folded in Tyvek. Each jelly contains its own RGB LED module. The 472ft² hanging surface was custom designed in 3D and fabricated from 6061T6 aluminum. Water jet cut and anodized on both sides, it comprises 154 generated triangles and 430 connector pieces.
Programed as self-contained objects capable of interacting with their closest neighbours, the Jelly LED modules are interrupted only by external intervention - the public engaging with the small display interface. Data is sent from an AIR app to each LED module via mbed wirelessly.

ake a modest notice about the two new Ladybug components, one of which creates a 3d terrain shading mask and another one which visualizes and exports horizon angles. A terrain shading mask is essentially a diagram which maps the silhouette of the surrounding terrain (hills, valleys, mountains, tree tops...) around the chosen location, and account for the shading losses from the terrain. It can be used as a context_ input in mountainous or higher latitude regions for any kind of sun related analysis: sunlight hours analysis, solar radiation analysis, view analysis, photovoltaics/solar water heating sunpath shading...
My home town is an example of the shading caused by the terrain. Here is how it looks from the tallest building in the town:
And the created terrain shading mask:
A mask for any land location up to 60 degrees North can be created:
There will also be a support for a few major cities above this limit.
Both Terrain shading mask and Horizon angles components can be downloaded from here. An example .gh file can be found in here.
Component will prompt the user to download and copy certain files in order to be able to run.
It was created with assistance from Dr. Bojan Savric. Support on various issues was further given by: Dr. Graham Dawson, Dr. Alec Bennett, Dr. Ulrich Deuschle, Andrew T. Young, LiMinlu, Jonathan de Ferranti, Michal Migurski, Christopher Crosby, Even Rouault, Tamas Szekeres, Izabela Spasic, Mostapha Sadeghipour Roudsari, Dragan Milenkovic, Chen Weiqing, Menno Deij-van Rijswijk and gis.stackexchange.com community.
I hope somebody might find the components useful.…
st between those two applications. But as soon as every frame is re-calculated I noticed that intersection function is very slow. It is actually so slow, that maximum number of polygons to play with is only 10 or less.
Could you help me to find a faster solution for my script?
calculation of intersection lines;
//////////////////////////////////////////////////////////////////////////////////////////
import ghpythonlib.components as ghcompimport rhinoscriptsyntax as rsdef ctr(crv): pts = ghcomp.Explode(crv)[1] pts = ghcomp.CullDuplicates(pts,0.001)[0] return ghcomp.Average(pts)pts = []lines = []ctr_c1 = ctr(C1)for crv in C2: if ctr(crv) != ctr_c1: int = ghcomp.CurveXCurve(C1, crv)[0] if int: [pts.append(x) for x in int] lines.append(rs.AddLine(int[0],int[1]))
/////////////////////////////////////////////////////////////////////////////////////////////
The overall description of the script:
a)Processing+ghowl is used for moving objects and physics
b)python script (slowest part) calculates intersection lines
c)intersected parts of polygons are rotated in 90 degrees.
I have attached grasshopper and processing files. (processing is not necessary to test the script)
Thank you in advance,
Pereas.

starting mesh. The geometry of the lines is then modified, through the formfinding routine.
In my second vb component, I need to build an array with 4 columns. Each row represent one face of the mesh (row 0 for face 0, row1 for face 1, ...) and each column represent the number of the edge element. If ABCD is the quad face, column 0 is the number of the edge AB, column 1 is BC, column 2 is CD and column 3 is DA.
So to build this array, I extract the edges of each face with FaceB component then Explode component, and I build the array by comparing each line coming from this to each line coming from MEdges component, with a 2 level nested loop. Here is where I am looking for an efficient way to compare 2 lines...
Is there an easier and faster way to build this array ?…
similar to any other surface in your model. Just model the shadings as surfaces and then assign either translucent material or transparent material (glass) to them and connect them to runDaylight with other Honeybee objects. Is that make sense?
Make sure to use appropriate numbers for -ab, -ad and -aa. Check page 27 of Daysim tutorial for a an example for parameters (https://dl.dropboxusercontent.com/u/16228160/Daysim3.0.Tutorial.pdf). I should add that the numbers are slightly high in the example though. Here is another reference if you want to know more about RAD parameters: http://www.radiance-online.org/community/workshops/2011-berkeley-ca/presentations/day1/JM_AmbientCalculation.pdf

you can open the studyFolder (it's one of the outputs of run daylight analysis component.) and check *.bat files. There is a rpict or rtrace line that you can see all the parameters listed. Mine is:
rpict -i -t 10 -vtv -vp 43.111 -74.673 49.782 -vd -0.433 0.750 -0.500 -vu 0.000 0.000 1.000 -vh 54.328 -vv 26.991 -vs 0.000 -vl 0.000 -x 64 -y 64 -af unnamed_IMG.amb -ps 8 -pt 0.15 -pj 0.6 -dj 0 -ds 0.5 -dt 0.5 -dc 0.25 -dr 0 -dp 64 -st 0.85 -ab 2 -ad 20 -as 128 -ar 16 -aa 0.001 -lr 4 -lw 0.050 -av 0 0 0 unnamed_IMG.oct > unnamed_IMG.unf
aa and ad values are changed in this example.

ace, the resulting surface does not exactly follow the curve. At the protruding edges, the surface falls out of the curve. Whereas at the edges which are going in, the surface forms is a curve of degree-1 i.e. not a smooth curve but lines.
What i want to know is, is this a normal thing in GH? when i have to print, will it print like a proper curve?
Also, at the moment, i have joined all curves together and connected it to surface component to get a surface. If there is any better way, please advise me.
I have attached the design representation and also part of my GH definition.
Any advise will be highly appreciated.
cheers

I am using grasshopper 0.8.0050 and Rhino 4 SR8. I tried uninstalling it, and then installing it again. The same. It is interesting that until yesterday, everything was fine. What could possibly be the cause of a problem?
Thank you.…
