Information

SpiderWeb

SpiderWeb is a .NET library providing functionality for preforming calculations on graphs. The library is created with a special focuse on the integration of graphs and graph related theroies (e.g. SpaceSyntax) in parametric design envoirnments. Therefore special Versions are avalible for:

Grasshopper
DesignScript (planned)

Any feedback, questions or critic is welcomed.

Documents

General introduction into graph theory

Documentation and samples

.NET documentation for SpiderWebLibrary.dll and GH_SpiderWebLibrary.dll

Dear group,

We would like to bring the following workshop to your attention:


Generative Syntax in Architecture and Urban Design
by Richard Schaffranek (Vienna University of Technology), Pirouz Nourian (TU Delft)

Abstract: There are a few theories that describe and explain the role of spatial arrangement on the social interactions of people in built environments, best known of which is called Space Syntax. The term syntax, taken from linguistics, here refers to the [spatial] structure of the whole, as opposed to morphology, which looks at the qualities of individual items. Using these theories, we can analyze existing spatial configurations and in a way measure their socio-spatial performance. However, theories and methods for systematically generating spatial arrangements of certain properties are rare or not put into practice. Combining analytic theories (mostly based on graph theory) with the generation of geometry is at the core of the workshop. In this workshop, we will introduce computational methodologies that can help in generating spaces with known syntactic properties. Three toolkits and methodologies will be introduced: SpiderWeb, Syntactic and Configurbanist.

You can also visit the Workshop Page for further details:

http://www.gbl.tuwien.ac.at/Archiv/digital.html?name=AAG2014


The workshop will be held as part of the  Conference "Advances of Architectural Geometry 2014" at the UCL from 18 - 21 (20,21 workshops) of September. It is possible to register for the Workshops independent of the conference.

To do so please follow this link: http://www.architecturalgeometry.org/aag14/?page_id=554

Best regards

Hmm, can't realy tell....

Maybe you can ZIP the project an send it VIA mail. So I can have a look? Never tested the library outside grasshopper scripting components...

Using GH_GraphVetexList visual studio is throwing the following error:

Error    1    The type 'Grasshopper.Kernel.Types.IGH_Goo' is defined in an assembly that is not referenced. You must add a reference to assembly 'Grasshopper, Version=1.0.0.20, Culture=neutral, PublicKeyToken=dda4f5ec2cd80803'.    H:\Load Takedown Tool\LTDT SVN\Load Take Down Tool\Components\Component_TributaryAreaAnalysis.cs    165    13    Load Take Down Tool

Unfortunately I *do* have a reference to Grasshopper and the correct version. Any ideas?

Hi, could you please take a look at this discussion when you have a chance: http://www.grasshopper3d.com/forum/topics/multiple-shortest-walk

Comment by Richard Schaffranek on February 3, 2014 at 6:06

Will include this in the next release...

Comment by Richard Schaffranek on February 3, 2014 at 6:06

You can get the StartingPoints/EndPoints of an Eulerian Path but the path it's self not, but actually it is rather trivial if you know a little vb or c# the Algorithmen can be found: 

http://en.wikipedia.org/wiki/Eulerian_path#Hierholzer.27s_algorithm

and an Introduction of how to use SpiderWeb Library within VB/C# components can be found under:

http://www.gbl.tuwien.ac.at/_docs/GrasshopperScriptum/GrasshopperSc...

there is also a .NET documentation (see link a both)

Hi,

Is it possible to solve the Euler path of a graph using Spider Web? I want to order all the vertices of a graph to create a polyline that goes through all the edges of the graph but never twice.

Thanks Richard!

Hi Richard, 

Thanks for your reply. Under security, there wasn't any option related to blocking or unblocking! My windows needed some updates though. Now everything works fine! :)
