algorithmic modeling for Rhino
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.
General introduction into graph theory
Documentation and samples
.NET documentation for SpiderWebLibrary.dll and GH_SpiderWebLibrary.dll

Hi ! i am very interesting in combine space syntax with grasshopper , and i have seen the 3.2 version spider had "shortest path angular" "shortest path"component to calculate the segment angular…Continue

HiI am quite new to graph theory and Spiderweb. I was wondering if there is a way for me to evaluate the betweenness of a graph.I created directly a dual graph from a series of spaces (no lines are…Continue

If you take a closer look at the scriptum library there is an example there using BFS -> topologic shortest path in terms of space syntax
http://www.gbl.tuwien.ac.at/_docs/GrasshopperScriptum/GrasshopperSc...
.NET documentation:
http://www.gbl.tuwien.ac.at/_docs/SpiderWebLibraryDoc/index.html
everything there is is what is under Documents section, no more no less sorry.
Again, brain dump...
If you are looking for a more complete library there is a python library for graphs but e.g. it misses spectral graph operations...
Thank you , I see both representation of the graph and geometry within the components.
Would it be possible to get and example of shortest path in .NET?
Maybe you have a github where you share some of examples?
Don't understand, the display components are used in the example. they preview into rhino viewport.
if you are asking for something like graph drawing you can use the eigensystem component to produce a somehow meaningfull drawing into rhino, please read:

Spiderweb is my personal brain dump so not everthing is there...
One more question, does the spider web has a "graph viewer" for representing graph without displaying actual geometry?
Just as in your website as nodes and edges in between?
Would it be possible to get an example for it two?
@2: Please define the longest Path, maybe it is possible with your specific definition. However please read: https://en.wikipedia.org/wiki/Hamiltonian_path, especially the section about NP-complete...

Dear Richard,
Thank you for a quick reply.
Would it be possible to get a simple shortest path example between point A and point B as target?
Also is it possible to find longest path between node A and B?
Thank you,
Tomas
Hello Tomas,
Have you had a look at:
http://www.gbl.tuwien.ac.at/_docs/GrasshopperScriptum/GrasshopperSc...
besides this, I am sorry and currently I don't realy have the time to extend them. However if you have specific questions please post them in discussions, I will be able to help.

Hi,
Is it possible to find spider web example files? The files found on mentioned website seems to be poorly documented. It would be good to have list of gh files as examples.
Thank you richard,
This is really a great tool !
Well it's giving you back a graph which you can use again to compute the shortest path (smallest Distance) between each pair of nodes..
see attached file
Best
Richard
