SpiderWeb

Information

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.

Comment by Jonah Hawk on July 13, 2012 at 14:59: Here the graph is created from rhino rectangles placed using array. Are the diagonal lines created by the Graph From Cells component because of rounding errors in rhino?

Comment by Jonah Hawk on July 13, 2012 at 14:36: I have a simple grid of cells using a rectangular grid component. When I remove some of the cells before feeding them into the Graph From Cells component, the distances contain mistakes. I'm sure it is a simple issue somewhere. But I can't figure it out.

Comment by Richard Schaffranek on January 26, 2012 at 14:24: There are more samples of how to use spiderWeb with the download.

You can apply it to freeform surfaces but as mentioned before overlaps are not taken into account. You would need to adapt the definition.

Graph as in Graph theory....

Basically a simple tree representation. For each vertex point there is a branch, each number in the branch reveres to a vertex point it shares an edge with.

Comment by Steve Lewis on January 26, 2012 at 14:17: Ok I'll check it out.

Two more questions.

What do u mean by a graph? I presume it's not just a 2d plot of values

Where would I use spider web?

Can u apply the drainage pattern definition to a fee form surface or must it be faceted?

Comment by Richard Schaffranek on January 26, 2012 at 14:00: If you download the latest version from the homepage, the script is included.

From a point grid on the surface you create a simple graph where every vertex point has eight neighbours. Then you choose, for every vertex point, the neighbour with the largest negative z - difference and delete the rest.

The minimum values are those vertex points without a neighbour.

Of course this is not so nice and for example it would need some adaptation to take overlaps into account.
