or a reparameterized curve. It's not! This is demonstrated by splitting the curve using the 't' values and measuring the lengths, which in the case below are either 2.0 or 3.0 (domain bounds and random integers). As you can see, the actual lengths don't match those integer values:
I remembered doing this before and found my code in this thread from January, 2017:
divide curve by distance between points http://www.grasshopper3d.com/forum/topics/divide-curve-by-distance-...
So I modified that code to use 'DivLength' (along the curve) instead of 'DivDist' (straight line between points) and combined it with the code I posted earlier in this thread. Notice the results in the upper right yellow panel - exactly the lengths expected. This requires Anemone and clicking the "Trigger" button to restart the looping:
P.S. The points are available at the 'D1' output of 'Loop End'.…
i have to rely completely in passive means.
To speed things i'm calculating comfort for Extreme hot/cold week, thinking maybe on typical weeks instead.
The cool week is kind of "right", but the hot (extreme) is giving all night hours 100% comfort. Knowing the climate, there is no way this can be the case. Some of the settings with the european standards give sometimes the right tendency, but still, compared to ASHRAE's the average of % percentage is too high.
Also my assumptions for flexibility of use/clothing/etc is the maximal. I mean, no constrains on this respect ("let's be passive as much as we can").
So right now i have no specific questions, but rather your advice, if any: "What you would do ...?? (I don't like these kind of questions, sorry).
A request, yes, if it is possible to output the set temperature for each hour. For instance, when you give the degFromTargetMtx i'll like to know this target. This is for control, and i think this is important for better understanding this black box.
Any other insights you may have, just shoot.
Not related to the discussion, but if you happened to check the model, we are simulating 2 apartments in the building. The northern one is only one thermal zone. The southern is divided in rooms. I wanted to see how much difference e get between both ways. And there is. No doubt the more detailed modeling looks more reliable. Also if you have some points here, shoot again.
BTW humidity, look at page 32-33 in the AC book. Nicol is clear on the "real" influence of the humidity, arguing it is mostly psychological than real.
Thanks again, and to you too Mauricio.

le with you.
I am trying to achieve the minimal path algorithm of Steiners tree in Python using the minimal path algorithm.The syntax would be as followsFirst I need to create a cube of any dimension.
Then I need to specify one origin say point A and destination point say B.
Now for this point A,B I need to create a machine based network which will automatically enroute A to B.
Where the angle will be constant i.e 120, length can be a variable, triangular node(steiners tree)using these constraints it will create a network.
Now, I should iterate the program in such a way that I should specify the further points say like A1 and B1 so on.The program will contain a limit constraint where it will come out of iteration loop and start a new loop,forming the network.
By this I will get a dense network of 120 deg branches.
The branching gets denser the moment I add source and destination points.
There can be 100 iterations to reach from A to B but the algorithm chooses the one following the minimal path.
I would be highly thankful to you if you would please share the python syntax and grasshopper definitionCapture.JPG for the same
Thank you for your time in advance
I would be highly grateful if you help me through
warm regards

Integer = 0 To 9
val *= 2
lst.Add(val)
Next
Since val is a ValueType, when we assign it to the list we actually put a copy of val into the list. Thus, the list contains the following memory layout:
[0] = 2
[1] = 4
[2] = 8
[3] = 16
[4] = 32
[5] = 64
[6] = 128
[7] = 256
[8] = 512
[9] = 1024
Now let's assume we do the same, but with OnLines:
Dim ln As New OnLine(A, B)
Dim lst As New List(Of OnLine)
For i As Integer = 0 To 9
ln.Transform(xform)
lst.Add(ln)
Next
When we declare ln on line 1, it is assigned an address in memory, say "24 Bell Ave." Then we modify that one line over and over, and keep on adding the same address to lst. Thus, the memory layout of lst is now:
[0] = "24 Bell Ave."
[1] = "24 Bell Ave."
[2] = "24 Bell Ave."
[3] = "24 Bell Ave."
[4] = "24 Bell Ave."
[5] = "24 Bell Ave."
[6] = "24 Bell Ave."
[7] = "24 Bell Ave."
[8] = "24 Bell Ave."
[9] = "24 Bell Ave."
To do this properly, we need to create a unique line for every element in lst:
Dim lst As New List(Of OnLine)
For i As Integer = 0 To 9
Dim ln As New OnLine(A, B)
ln.Transform(xform)
lst.Add(ln)
Next
Now, ln is constructed not just once, but whenever the loop runs. And every time it is constructed, a new piece of memory is reserved for it and a new address is created. So now the list memory layout is:
[0] = "24 Bell Ave."
[1] = "12 Pike St."
[2] = "377 The Pines"
[3] = "3670 Woodland Park Ave."
[4] = "99 Zoo Ln."
[5] = "13a District Rd."
[6] = "2 Penny Lane"
[7] = "10 Broadway"
[8] = "225 Franklin Ave."
[9] = "420 Paper St."

gn , New LabCities are continuously produced through entropic processes that mediate between complex networked systems and the immediacy urban life. Emergent media technologies inform new relationships between information and matter, code and space to redefine new urban ecosystems. The NY GSS aims at investigating emerging forms of reading and producing PUBLIC SPACES re- imagining the physical city through intelligent and mediated processes.Through data agency and responsive urban processes, the NY GSS will explore the connection between the production of emergent forms of URBANITY and fabrication/robotic/responsive practices. Focus will be placed on the feedback mechanism between scales, investigating the continuous loop between the micro and the macro relationships that occur in public spaces. The city of New York will be the expanded site of exploration. The investigations will critically reflect on the city as the shared, the common, the civic and the social-public enterprise.Generative design and computationally driven processes will take place throughout the program. A series of lectures from leading academics and international invited guests will construct the theoretical framework of the GSS, integrating and expanding the learning modules, with a final exhibition and promotion of the work.…
ecember 2017 from 18:30 until 20:30. We will have presentations from Heatherwick Studio and AKT II.
Please visit the following page for more details and registration: http://simplyrhino.co.uk/events/upcoming-events/grasshopper-uk-ugm-2017
Heatherwick studio will present two projects covering the topic of designing, making and collaborating through computational tools. Heatherwick’s Geometry and Computational Design team will go through the computational processes behind design and making in the studio concentrating on two projects, Vessel in New York with a focus on driving the geometry and Al Fayah Park in Abu Dhabi with a focus on Form Finding and working with collaborative tools.
AKT II's presentation will explore a series of examples where this new approach was experimented, tested and improved, the Al Fayah Park in collaboration with Heatherwick studio and the 2016 Serpentine Pavilion with BIG, and more.
We're looking forward to seeing you all again!
Many thanks,
Paul and Arthur

archaic in it's whole structure. Good for some limited things but not too much fun in the long run in 2017.
Still I learned a lot here, some of it from you, and for that I'm very thankful! :-)Losing all that content is indeed bad.
But I personally can't see McNeel as "evil" while I have no problem seeing Autodesk as such. They killed XSI (my tool of choice for almost 10 years) and now plumb XSI ICE into Maya - no thanks.
I too can't see myself buying Rhino 6 ATM, since like you, I think it's a bit underwhelming in scope and the new licensing doesn't improve things.
At one point it's time to move on, even if it's hard and needs letting go of grudges - I can be just as emotional about software as you, but the energy spent on trying to make Rhino/Grasshopper into something it's not is simply wasted.
Thankfully I finally found a new home softwarewise, I went through many of the applications you mention but they all have their own flaws and limitations. SideFX at least have the right spirit, Houdini moves along joyfully, problems get fixed fast with daily builds, support is great, the software handles big assets easily and the combination of nodes and code (Python, VEX...) is a joy to use for my generative work. The community is amazingly helpful and communicates often on a very high level (for instance forums.Odforce.net). Works for me :-)
I wish you all the best in your journey and again, thank you for the insights I gained from your posts in the past.
Cheers,
Tom…

La circunferencia del cilindro se dividiría en seis regiones, tres “valles” habitables alternando con tres hileras de ventanas que permitirían el paso de la luz solar. Además existiría un anillo exterior para la agricultura de quince kilómetros de radio, el cual gira en una velocidad diferente a los cilindros. La zona industrial y la fabricación estaría localizada en eje del cilindro, detrás de la antena parabólica. En esta zona la gravedad es mínima, algo que se tendría en cuenta en algunos procesos de fabricación y otras actividades de la colonia.…
