lies on gradient-free optimization algorithms, delivering fast and deterministic results. At every run, goat will yield the same optimal result.
goat is a drop-in replacement for galapagos. It is based on David Rutten's galapagos GUI and interfaces NLopt, a collection of mathematical optimization libraries.

For getting started with optimization in parametric modelling environments in general and with goat in special, check out our presentation slides on Geometry and Optimization with several comprehensive examples.
Once you are familiar with the basics of optimization, head over to our comprehensive documentation on goat's different configuration options.…
t BBox will then be mapped relative to the UVW space of that box to the new target boxes.
Where your definition is slipping up is the data matching aspect of GH. You have two lists (that count). One list contains 100 items of target boxes and the other contains 2 items of geometry. GH defaults to the Longest List data matching
List A --> List B
Target Box A0 --> Cuboid
Target Box A1 --> Cylinder
Target Box A2 --> (Oops List B has run out of items. Now GH will repeat the last item = Cylinder)
Target Box A3 --> Cylinder
.....
Target Box J9 --> Cylinder
Solution
There are two approaches to rectify this the most logical would be to group the geometries into one object (What you had in mind with the bounding box) to do this use the Group Component on the Transform Tab > Utility Panel.
The other approach is far more common in GH mentality. Use the Graft, right click the G input of Morph and select Graft from the Context Menu. This places all of the items in the List on to separate branches. Creating a list of lists (although these new list only have one item). When GH now tries to data match them it will apply the whole of the first geometry list (Only the Cuboid) to all of the target boxes and all of the second list (Cylinder) to the target boxes again.
I hope this helps…
p, open to designers worldwide, will explore the parametric mix of new raw materials and the re-use of elements from Carnival floats and costumes, transforming them using generative design processes and new digitally fabricated joint components, to create interventions for micro-venues and urban furniture in the Porto do Rio region.
Taught by AA Staff, recent AA graduates, and computation and fabrication professionals, the studio-based workshop will include extensive instruction in Rhino Grasshopper (including GECO, and Galapagos, to integrate environmental optimization, simulation and parametric control) and digital fabrication processes using laser cutter, CNC-milling and rapid-prototyping machines, sponsored by DS4 and SEACAM, all of which will be used to produce one-to-one design prototypes.

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.

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

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

th one element which is a list of 10 numbers?
I can flatten it and get (I think) a list of 10 elements (even though when I hover over the output of "Flatten" it says "Tree(T) as tree"). I'm surprised I can flatten at all what would appear to common sense to be a simple list of 10 numbers.
I'm hoping that if I can get this answered it will become obvious why we have trees of lists rather than just lists of lists as you would in most computer languages. That's my real goal - to understand the purpose of adding what seems like an unnecessary complication - trees - to the concept of lists in GH. It seems to me as though a "tree" is just a list of other "trees" until you get to the leaves where you can have "lists" which are identical to trees but can have something other than a tree in them. Whether you can have lists of trees or trees with no lists I'm unclear on. Do the leaves of trees have to be lists? Do lists have to be contained in trees? It would appear from the series example where a tree is produced for no obvious reason to contain the list that this is the case but given that you can flatten it, I guess not - or is the "List" I see in the param viewer just another type of "tree"?
I've found many tutorials that talk about how to manipulate trees and lists and I've managed to get along fairly well with them so far, but nothing seems to explain the reasoning behind the existence of trees and the philosophy for how and when they should be used and when lists should/could be used and precisely what the difference is between them.
Sorry to be long winded but I'm so confused!
Darrell Plank
P.S. I've seen David Rutten's diagram with the colored leaves in Grasshopper Primer 2 and that seems helpful. It would appear that trees can only have lists at their leaves and lists can't have trees although I'm not sure that it comes out and says that directly but at least there are no examples of this shown in his tree diagram. I thought I had it down pretty much so decided to test myself. Apparently I'm as confused as ever:
It certainly appears to me that this tree has two levels - a first level with one limb and a second with 10 limbs - and that I should be able to index it with {0;0} and retrieve a tree with one item in it - the list {0}. The panel data seems to confirm this with indices of {0;0;0}, etc. so I put this path in with quite a bit of confidence that it would work and...bust. The error reads "Path {0;0} does not exist within this tree". Huh? Again, I'm just so confused.…

this workshop is to materialize a chair designed with help of generative algorithms via robotic fabrication. To design the form of the chair we will go through an intensive course of generative design techniques, k-means clustering, structural analysis and optimization done with the help of Anemone, Galapagos, Millipede and other plugins. Finally we will employ a 6-axis robot with custom tooling to fabricate the chair via robotic rod bending. No prior experience with Grasshopper or robotic fabrication is required, although basic knowledge in 3d modelling would be an asset. // APPLICATION The deadline for application is 13.03.2017 Apply by sending email titled ‘workshop_chair’ to workshops@aan1.net // INFO If you have any more questions check the www.aan1.net website or contact us with email workshops@aan1.net // FEE We have special pricing for students, as well as an early bird offer.
