Space Syntax

Space Syntax is a theory of architecture and built environment that seeks to explain the effect of spatial configurations on behavioral patterns of people. SYNTACTIC tools bring Space Syntax theory into parametric design workflows.

Hi, All components are ready. We are just wrapping all our VB codes into a GHA.

Hi Matthew, thanks for your kind words! happy to hear you find the tools useful. Perhaps you can follow the instructions/pseudocode in my PhD and make a 3D version of this algorithm with the help of Kangaroo. I can then translate it to C# and include it.

Hi Pirouz,

really appreciate your help. I am currently installing the new version of cheetah and will have a look into the Spectral Graph Drawing tool. I have read through a couple of the chapters in your phd and now have a better understanding of the Force -Directed Drawings and why I was not achieving a good result. The list of areas, spaces and connections I was using for input were a bit complicated. I will simplify and have another go. Love your work : )

Hi Matthew, just tried to open your Rhino file, but it is not saved properly as a Rhino file. Can't open it. Anyhow, I am familiar with this question. The thing is, a coin graph like the one you expect from a Force-Directed Graph Drawing algorithm might not be possible to draw given the list of areas, imagine fitting a 2 Euros coin in the middle of four 5 cents coins. It does not fit. A force-directed drawing algorithm is a heuristic algorithm; meaning it is not guaranteed to work; but it often does. It is theoretically not guaranteed to converge to a solution. If you would like to see something sensible you can lower attraction and repulsion to get a better picture of the situation. You can also use the 'Spectral Graph Drawing' tools of Cheetah (only the new version available on the forum) or Spider Web for getting a picture of your spatial network.  

more info on the force directed algorithm and the whole process:

Hi Pirouz,

I'm having some trouble producing a functional Disk Graph Drawing that uses the NGV output from the Force Directed Drawing component. It appears that the repulsion & attraction forces are not performing correctly. I continue to get an error message from the Disk Graph Drawing component that reads:1. Solution exception:Object reference not set to an instance of an object. See posted files Norwst_02.ghNorwest_02.3dm

Thanks Rich & Pirooz

I'll try my best
Hope to succeed

Hi Richard, thanks for the hints. It's funny why one sometimes feel uncomfortable mentioning GH :)). Could you please point to some of these Field-of-View algorithms implemented in GH? Have you ever tried using this one: http://www.cse.chalmers.se/edu/year/2015/course/TDA361/grid.pdf

Hello Maryam,

I don't think it is a depthmap upgrad. If you look up the paper and take a look at figure 4 / 5 you see the standard Rhino3d Isocurve display of cubes. For some reasons people do not want to say, it was done with grasshopper....

If your up recreating 3D IsoVist analysis I suggest to find a good 3d FOV algorithm - there are some around in GH forum. Once you have determined what voxels are visible form a  voxels you can use spiderweb to run BFS and than compute what kind of integration Value you would like to compute (RA,RAA,I).

However these things get very pricy (computational wise) as visualGraphs are always very dens.

I was thinking of implementing BFS on GPU at one point, than things should be a bit faster...

Best

Richard

I e-mailed to Dr. Tasos Varoudis and Dr answer to me:

This examples were done with a custom software, not available in public.

You need to use your own scripting to do something like this at the moment.

I think it is an upgraded version of the Depthmap software. Did you notice the two-dimensional to three-dimensional version upgrade it?

Comment by Pirouz Nourian on March 22, 2017 at 5:37am

Hi Maryam; Happy Nowruz

I think it is done in GH by Dr. Tasos Varoudis @UCL. That is all I know. I don't know if their app is available. If you want to do visibility studies I'd suggest using SpiderWeb

Comment by maryam on March 22, 2017 at 2:48am

Hi Pirooz

Happy New Year

This Picture attached, refer to an article, published in the Journal of Space Syntax

This article refers to software. that is as far as I know is currently not available

?Did you know that & time of publication the software

I am grateful that I guide
