akes the linear regression of the Schroeder integral over 30 dB worth of decay. Whether it is T-15 or T-30, they all seek to estimate the RT, which is always always the time it takes for sound to decay 60 decibels.
The website has benchmarks, for your reference. You can find them under the 'Pachyderm' drop down menu, under 'Benchmarks'.
Your model may well require millions of rays to be accurate. It sounds like a very large space. I'm sorry if that is an unpleasant answer. Sometimes it does help to have a computer with more cores to help with this. I have gotten up to 90% processor usage on a 12 core machine before.

hat differ in shapes, sizes and height the facade would be a mess. Some spaces need some light while other can't have any. I would like to have full freedom of creation inside the building, to make it as functional as possible. Thats why i decided the parametric "skin" solution would be best. Since the location has industrial past (factories made of brick) i decided that brick would give interesting result.
I tried creating the definition on my own but since i lack skill in GH i got some problems (especially multiplication of bricks and the diffrence between each "level" (half a brick on y axis) caused problems for me.
I post my simple sketch explaining the idea of definition i would like to create (sorry about quality):
1 - Brep - I would like to use 25x12x6cm (classic brick) but as well experiment with diffrent shapes - like the one on the right with hole inside - that would give more light. Thats why i think the best solution would be using brep for this definition.
2- Multiplication - biggest problem for me - I don't know how tall the wall would be, what will be the final shape of Brep (brick) and that's why i would like to manipulate this with sliders as well. All the walls are flat (maybe it would be easier to use surface?). As i managed to multiply the bricks easy way i don't know how to gain control over height of the wall - for example that it is 30 bricks high, but has each second row moved on x axis by the distance of 1/2 brick. I tried using Series but with no success. Could you help me with that please?
3 - Rotation - i would like to use image sampler for that so i can "paint" where i want more sun and where i dont need it at all (black and white). The rotation has to be limited to 180 degrees as well. Obviously i didn't get here yet, but i never used image sampler so if you could give me some advice how to use component and how to create such images i would be really grateful.
4 - More of a concept thing - since the connection angles differ from 90 degrees i will have to figure out how to connect the parts of the wall at sides ;).
I would like to ask you for help with the defintion, since i am totally stuck at step 2. I post what i came up with so far. Thank you for your time and help!
PS. I post an image that is pretty similar to one of options i would like to check for my building.

writing a solar-angle component, but I've never gotten around to that.
Dates are stored as 64-bit integers. Basically they count Ticks (1 tick = 100 nanoseconds, or 1 second = 10 million ticks) since midnight, January 1st, 1 AD. Formatting comes into play only when the time is represented as a String.
A wide variety of formatting flags is possible Dates, unfortunately the Grasshopper Expression language doesn't support the DateTime type, so it gets converted to Strings automatically. This makes formatting dates and times impossible. I'll probably get around to adding the type at some point, or maybe I'll make a dedicated DateTime formatter component (less work, but also less flexible).
I also do my best to interpret any string that might represent a date or a time:

catch-all phrases that pick up all of the rest of it: you have inputs, algorithms, and outputs.
It sounds like you don't necessarily want to wade into the miasma of academic reflection on the terminology, but in case you're willing to hold your nose and brave it there is some fairly interesting stuff out there. Nick's point about computation versus computerization is pretty reflective of a common mode of thinking about it. AD published a book edited by Sean Ahlquist and Achim Menges a couple years back called "Computational Design Thinking" and their introduction lays out a compelling argument for the distinction. Likewise Philip Galanter's paper "What is Generative Art? Complexity Theory as a Context for Art Theory" is a good read.
I mean, ultimately it's about semantics. If you're worried about "real, accurate meaning" the reality is you're going to have to justify the boundaries of your own definition one way or another. David is rather a wry literalist who I suspect enjoys taking the piss out of academics, particularly when they're all puffed up (and really, every event is a form of computation if you want to go there). But usage counts, and there's a growing body of work staking claim to these terms, so it's better to know how and why if you even want to ask the question.…

t the elements I used CreateHBsrfs and I added "Adiabatic" in the EPBC input. Since the EnergyPlus results weren't what I expected, I checked the idf file and I discovered none of the element is adiabatic. Furthermore, the simulation doesn't use the materials I set up for the not-adiabatic wall.
I even tryed with MakeAdiabatic, MakeAdiabaticbyname and MakeAdiabaticbytype. With the first and second the problem is still the same. With MakeAdiabaticbyType, if I change one wall type in the CreateHBsrfs, it still remains the same type in EnergyPlus, so it makes all the walls adiabatic. Is there something I can do? I attach the GH file Thanks in advance Lisa…
The type of recipe appears to be related to the problem, because de error desolves when I connect the component to a different recipe.
A screenshot of the complete error message is in the attachment.
Error text:
0. Annual climate-based analysis1. The component is checking ad, as, ar and aa values. This is just to make sure that the results are accurate enough.2. Good to go!3.

Many thanks in advance…
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

ALISTICO. Ciascun modulo si svolgerà nell’arco di due giornate e si potrà scegliere se partecipare ad entrambi i moduli o altrimenti solo all’uno o all’altro.
In questo corso si insegneranno nuove tecniche di modellazione parametrica attraverso l'utilizzo di Grasshopper, rivoluzionaria plug-in di Rhinoceros. Grasshopper permette di esprimere al massimo le qualità e le potenzialità della modellazione Nurbs, abbandonando in parte l'interfaccia classica di Rhinoceros. Quest'ultimo infatti viene sostituito da un menù a tendine nel quale vengono collezionati nodi utili alla composizione di algoritmi risolutivi.
La plug-in Grasshopper, dimostra come il linguaggio del computer stia diventando un reale strumento progettuale.GRASSHOPPER-BASE - 8 oreil giorno 09/05/2013 dalle 10.00 alle 19.00
Nella prima parte del corso si insegneranno i metodi di esplicitazione degli algoritmi, applicati ad esercizi base utili alla comprensione del software. In queste ore si illustreranno, attraverso fasi operative, i seguenti argomenti:
Suddivisione degli algoritmi in parametri e componenti;
Tipologie di dati compatibili con Grasshopper e loro combinazione creando definizioni minime;
Funzioni matematiche e logiche
Data flow, liste e filtri di esclusione.
Costruzione di curve e superfici e loro trasformazione.
Scadenza preiscrizione per Grasshopper - BASE : 06/05GRASSHOPPER-SPECIALISTICO - 8 oreil giorno 10/05/2013 dalle 10.00 alle 19.00
Nella seconda parte del corso lo strumento viene specializzato affrontando editing e trasformazioni complesse sulle superfici:
Elaborazione delle superficie di suddivisione;
Tassellazione spaziale di superfici a doppia curvatura;
Gestione di parametri variabili per la progettazione di definizioni finalizzate al controllo del movimento;
Ideazione di algoritmi per il passaggio dal modello digitale al modello reale attraverso la tecnica dello sliceing.
Scadenza preiscrizione per Grasshopper - SPECIALISTICO : 07/05
