Grasshopper

algorithmic modeling for Rhino

plugins: karamba, lunchbox

feeding in any type of geometry, the definition tries to do the rest to make karamba work.

auxilliary plug-ins: meshEdit, weaverbird
optional analysis plug-ins: spiderweb

Hi Robert,

Is there any chance you wouldn't mind giving me the definition for this for my student project?

Many Thanks,

Annabel

Any further components you think would come in handy for these tasks?

Hi Richard,

mainly I've been using SpiderWeb in two ways:

1) Instead brute-force Nearest-Neighbor or ClosestPoint searches, mostly for preparation of geometry for fabrication.

2) Checking a karamba-model for disconnected parts via breath-first search. Now we have a component in karamba that also does the job, but just for karamba-models as an input.

best,

Robert

Hi Robert,

Since you are using SpiderWeb in a total different area I was wondering if you could give me some feedback about the application of it? It would be create in order to develop it further.

thx

Richard

in short - breps, meshes, curves and lines are intersected, split, and woven with each other depending on the overall size of the model. scaled cross sections are assigned, and iteratively fit in size towards 100% utilization. supports are placed in the lower X% (e.g. 10%) of the bounding box, and for analysis a number of graphical outputs are preconfigured.

for easy debugging, the processed geometry is analyzed for connectivity (the necessary property for karamba) with fast graph analysis (spiderweb).

tricky parts are performance of the geometry processing and its robustness (=working for any configuration), but for now it's not too bad

seems interesting. Care to share more about the workflow?

gravity load on a truncated octahedron. principle stress trajectories left, force flow lines (global z) right

i ll try to post some more the next days

So.. what are you doing? Looks interesting...
