of Space, 1984) and specified in (Turner A. , “Depthmap: A Program to Perform Visibility Graph Analysis, 2007), intuitively describe the difficulty of getting to other spaces from a certain space. In other words, the higher the entropy value, the more difficult it is to reach other spaces from that space and vice-versa. We compute the spatial entropy of the node as using the point depth set:
(11)
“The term is the maximum depth from vertex and is the frequency of point depth *d* from the vertex” (ibid). Technically, we compute it using the function below, which itself uses some outputs and by-products from previous calculations:
Algorithm 4: Entropy Computation
Given the graph (adjacency lists), Depths as List of List of integer, DepthMap as Dictionary of integer
Initialize Entropies as List(double)
For node as integer in range [0, |V|)
integer How_Many_of_D=0
double S_node=0
For depth as integer in range [1, Depths[node].Max()]
How_Many_of_D=DepthMap.Branch[(node,depth)].Count
double frequency= How_Many_of_D/|V|
S_node = S_node - frequency * Math.Log(frequency, 2)
Next
Entropies [node] = S_node

ice 2007. So I went out and bought Office 2010, and all my Excel interopservices vb.net scripts are now failing. They had all worked fine before...now when I execute they give the following error:
error: Invalid class string (Exception from HRESULT: 0x800401F3 (CO_E_CLASSSTRING)) (line: 0)
Here's the boiled down script:
If activate = True Then
Dim oldCI As System.Globalization.CultureInfo = system.Threading.Thread.CurrentThread.CurrentCulture
System.Threading.Thread.CurrentThread.CurrentCulture = New System.Globalization.CultureInfo("en-US")
Dim xlApp As Object
xlApp = System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application")
Dim xlSheet As Object
xlSheet = xlApp.ActiveSheet
xlSheet.Range("A1").Value = "test"
End If
The failure happens with the addition of the InteropServices line. I'm mid-project right now, and it's pretty critical that I regain the ability to go back and forth from GH to Excel in the scripting environment...does anyone know if I need to deactivate any security options in Windows, make sure any dll's are properly installed...anything? I've tried all of the other Excel components that various users here have already been generous enough to share (my scripts are all based on them). I can't seem to find any documentation (that I understand) about this particular error message, or how to fix it. Really could use a little help!
thanks in advance,
Dave…

is post on the same subject: http://www.radiance-online.org/pipermail/radiance-general/2008-March/004856.html
But I don't understand exactly how to assign the materials to the surface.
When I use the Honeybee_CreateHBSrfs component it gives me an error:
1. Solution exception:Faild to import void glass glass_alt_mat003 0.96 0.96 0.96
void brightfunc glass_angular_effect2 A1+(1-A1)*(exp(-5.85*Rdot)-0.00287989916) .01 0.08
glass_angular_effect mirror glass_mat1 glass_alt_mat03 1 1 1
Have you ever solved the same issue? If possible, how would you simulate this effect with Honeybee?
Any help would be appreciated…
correct:
- the right value in the 0. path {0;77} is the smallest one.
- right value in the 1. path {0;78} is the value which is closest to the chosen value in the preceding path
- ..and so on for {0;79} and {0;80}
but when the paths change their first level, the iteration should start from the beginning:
- right value in the 4. path {1;32} is the smallest one.
- right value in the 5. path {1;33} is the closest to the chosen one in {1;32}.
- right value in the 5. path {1;34} is the closest to the chosen one in {1;33}.
..to be continued.
..this is, what I want to achive in the VB code, I implemented at the beginning of the discussion.
..and this is how I designed the input-parameter of the VB-element:
if someone could help me .. super-great!

Mac due to its versatility , but given this new laptop will be using mainly on Rhino, GH , i have some doubts whether to switch to a window based laptop.
I have a look at some high-end window laptops, Dell Alienware for example, with same specs as MBP and found the price are even more expensive than MBP , about 10-15 %.
With the new Rhino 5 is coming , will Bootcamp be good and efficient enough to run Rhino, GH and some rendering programs?
From my experience i find Rhino and Gh run smoothly on Bootcamp , but never run those programs on window based laptop myself , it's impossible for me to know the differences.
Some say BootCamp only deliver 80% performance of the program , if it's true i would really consider switching to window based laptop.
Any suggestions?
and if you suggest me to switch , what brand should i go for ?
Thank you,

tunities offering new tools and ways to understand dataflow, performance analysis, logic constructions, etc. Over that statement, I've always observed that a definition is full of information at component level or small groups, but that informed-user-feeling disappears exponentially while you zoom out an get a more general picture of a big definition (small definitions are not a problem due to the good level of information supplied at that zoom factor).
So I though, why not to use this graphic potential to lead to a more complete data representation at low zoom factors in big/very big definitions? Have you ever noticed how annoying is to review big definitions captures printed in A1 project panels? These captures lack any kind of useful information (even if you are an expert in GH)...you can only conclude looking at them how organized or well planed was the definition coding process...but nothing else (not really, you can conclude other stuff, but not at the level that you could expect from a graphic-centric coding tool). Some users has invented ways to give more data to third-person users/tutors...: using panels with text scaled up, using scribble components, importing drawings from rhino...is even more frustrating if you want to explain how the definition works using one of those captures...there are not landmarks, etc to support your speech.
All this lead us to include certain components search (by name, plugin, tab...) into our mapping tool. Could be nice to be able to stack several layers of information visually, and it could lead to a better understanding on GH definitions as a whole and not as small pieces linked together.
Sorry for the big "tocho"...like we say in Spanish.
By the way, the histogram thing sounds great :D…

uld draw, lets say opening locations which would then trigger certain code. Its fairly easy to convert formating, a cell with a certain color, to code, so in a way I would be using excel as a super basic cad program to manage lists of data. In order to do this I need to be able to call some Excel commands from Rhino and to add some functionality to LAN's rhino to excel script (http://www.livearchitecture.net/archives/1516) I would like to be able to get the Ubounds and dimension of an array or a list. . . ie somehow get the equivelenat number of rows and columns of an incoming list of data and then use this to generate some graphics in excel but . . . . It seems that the sytax for excel Vb script via interoperability
marshaling is a bit different:1)I can not use
the set command ie Set range 2) it does not allow me to use the typical excel
syntax such as:
Worksheets("Sheet1"). Range("A1:D4").BorderAround
ColorIndex:=3, Weight:=xlThick
I get the following errors
Error: Method arguments must be enclosed in parentheses. (line 114)
Error: Name 'xlThick' is not declared. (line 114)
Is their an alternate way to write the Excel commands? Or is there something I need to do in Rhino? Any advice would be appreciated.
Best,
Ben…

cy of design communication and the control of information-flow are as important as the creativity of ideas. In response to the concurrent digital evolution emerging in the architectural industry world-wide, the Faculty of Architecture at The University of Hong Kong will host a two week intensive summer program named Digital Practice.Led by professors from The University of Hong Kong, as well as invited practitioners with expertise in practice of cutting edge digital techniques, the program offers participants opportunities to experience applications of computational tools during different stages of an architectural project, i.e. concept design, form finding and optimization, delivery, management and communication of design information under the team-based working environment. By learning advanced computational techniques through case studies in the context of Hong Kong, participants are expected to go beyond the conventional perception of technology, considering users and tools as a feedback-based entity instead of a dichotomy. The program, which is taught in English, includes a series of evening lectures related delivered by teaching staff and invited local architects.對於高品質的建築專案,創意之外,專案過程中高效的設計資訊管理和交流成為項目設計深化和實施必不可少的環節。今天,數字化技術不但改變了建築師的繪圖工具,影響了設計的過程,而且提供了工程建造和管理實施的更有效、更高效的手段。針對建築的數位化演進,香港大學建築學院將於2011年暑假期間,在香港大學建築學院舉辦“數位化實踐”國際研習班。在香港大學建築學院教授及有著相關豐富經驗的外聘實踐建築師的指導下,學員將有機會體驗在專案的不同階段(如概念設計、設計形式的生成、優化,設計資訊的管理和交流),如何有效地應用各種運算智慧化技術(從設計的數位化生成和建築資訊類比到物理模型),提升設計實施的品質,增加設計團隊對於方案的控制。我們將挑戰對於“技術”的傳統認知,即相對於使用者它不僅是工具,更是與使用者互動的媒介,二者形成一個有機的合體。研習班期間會安排系列講座,展現數位化技術在實踐工程中的廣泛應用。…
