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.

on this, but to my understanding, the Δt_pr used is the same - the equations used to calculate are not. Take a look at this (from EN 7730 as well):
If I can make some wishes too; it would be cool, if you included the last local comfort metrics from EN7730 in LB/HB as well. Besides the local asymmetry there are: an equation for warm/cold floors, stratification and draught. I know, that you will need preform a CFD simulation to properly calculate stratification and draught, but the comfort equations are really simple and seeing that you have(might have) a CFD tool under way it could be useful. Anyways I think it would possible to import external generated CFD data to grasshopper.
The pictures in my previous post are from a paper called: "A simplified calculation method for checking the indoor thermal climate" by B.W. Olesen, it can be found in ASHRAE 1983, vol. 25, issue 5. I don't know if there have been any updates to it since '83.
Looking forward for the new components, and if there is anything I can help with please let me know.

ength is applied to particle b, and the same vector multiplied by -2*BendStrength is applied to a and c
Hope that helps. I was thinking of changing this input slightly for the next Kangaroo release, because I realize it can be a pain if you want bending stiffness of a curve to be independent of the number of points used, but I'll make sure to clarify any changes when I do update this.

an that HashCodes well ... since they are "unique" per item (even if this - for the one reason or the other - is created at the same location with that) I barely can see how one can use them in order to get rid if "equal" items (Lines in this occasion).
On the other hand ... well ... using HashSets sampling the Line center and testing length and direction ... well ... this works but why bother? > if you are not doing business with code (thus you need this "check" internally) > use the Kangaroo1 component.
That said the topic of "equality" is rather huge and most people are confusing a lot of things on that matter: for instance a point not equal to another ... well ... that's rather simple but a brep "not equal" with some else ... this is not that easy (if it's solvable).…
tract subsets, be sure you always perform the same actions on a list of increasing numbers. So, before you start to manipulate a list of 100 points, create a list of 100 integers (0, 1, 2, ..., 99) and make sure it gets mutilated in the exact same way as the pointlist.
Then, when all your points are modified, bring them all into the same list again and sort that list using the integer array as keys. This ought to put them back into the right order.
2) Reverse Engineering: since you know all your points are along well defined curves (lines in your case), you could project them all onto a line that spans the entire model. This will give you a list of curve parameters (floating point numbers). You can then sort your points once again, but this time using the parameters as keys. (See image: by sorting all the points using the curve parameters, you get the order in which they appear from left to right)
2b) If you need to do this thing on points which are in a grid (i.e. 2D sorting), you have to project onto a surface so you get uv parameters for every point. Then vastly multiply only the u (or only the v) values, since you want to give rows (or columns) a higher weighting. Finally add u and v together and this will give you another list of floating point numbers which can be used as a keys array in a sort operation.…
.0001, the functionality is been put into dedicated components (see this post for further details).
Different branches are always combined using Longest List logic. I'm unhappy about this as well, I need to give more control over how different branches are combined, but I haven't figured out yet how to expose such functionality without it being utterly incomprehensible to 99% of the users.
If you want to ignore the data inside the fourth branch, you'll need to remove that branch before the data goes into the Line component. It's easy to remove a specific branch, somewhat trickier to make this removal dependant on variables elsewhere in the network.
You can use the Split Tree component to achieve this either way. Using a fixed mask (like in the image below) may be sufficient.
The !3 means that any branch is allowed except when it has a 3 in that location. The [0-2] means that only branches which have a number in between and including 0 and 2 will be allowed.
