nd and downloading definitions to learn from them, but still don't get it right.
So my problem is:
1.- I want to achieve a kagome, hexagonal gridshell that keeps the bamboo pieces like straight geodesic lines.
2.- I also would like to keep the curved bamboo as splines, so I imagine this will give the easiest method for bending the bamboo at the real scale. As Mårten Nettelbladt in his blog http://thegeometryofbending.blogspot.jp/ mentions, the best way will be to keep the geometry where all the pieces have a spline curvature ( or as B.K.P. Horn calls it “The curve of last energy”) In order to achieve splines do I need to make the grid a Dynamic relaxation “Kangaroo”? will this help?
3.- I would also like to simulate the bending of the elements from a 2D to a 3D, but maybe this can be a next step on the definition…
Some of the common problems that I notice in the definitions found is that when people do weaving, the lines don't bend flat to the geometry but rather they twist so when you look close the cross of pieces intersect, which is impossible in real life…
As you can see there are a number od issues here, I apologize to put them all together, maybe it makes this confusing but I think is better to look at the whole picture. I have been reading a lot but I have no idea how to start.
The more I read the more interesting the subject becomes but the more confused I become. Is there some kind soul that could give me a hand? Any help will be really appreciated.
Thanks a lot!

o fix before it becomes very usable, but I'm posting the file here in case anyone wants to try it out.
It is a few simple scripts which record point locations from a first Kangaroo simulation whenever the capture button is pressed, and then when you playback the animation it interpolates between this captured sequence of points, pulling a second Kangaroo simulation to these targets. You can control the playback with a slider or automatically with a timer.
This should work with other Kangaroo2 setups, but here demonstrated with a human figure modelled as a collection of rigid bodies. At the knees and elbows the rigid bodies share 2 points to give a hinge joint, while for shoulders, neck, hips, ankles, wrists and torso they share only single points, giving a basic ball joint.
This is also the first time I've posted this model, and I'm also including the setup without the animation script. I know there are numerous issues with this poseable figure - dragging joints sometimes moves parts of the model you don't want to, and joints have unrealistic ranges of motion. I made a start at trying to limit some of these - such as ClampLength goals to stop the torso bending too much, but more could be done. There is also an issue with the rigid bodies (which track orientations with a frame of 3 points) that if you grab the frame itself, the simulation can break. I'm currently rethinking this whole approach.
I should also say that although I have heavily modified this human model to make it work for this setup, I did start from a mesh downloaded from some free 3d model collection site, but unfortunately I do not know the name of the original artist. If someone recognises it I would like to add appropriate credits.…
(http://www.food4rhino.com/app/quelea-agent-based-design-grasshopper) take like 40 seconds when the toggle activates to go from one end of the ramp to another.
With proximity 3d i'm analyzing each instance the agents are closer than x units. In picture 3 we can see that in 212 instances the agent are closer than those x units.
Finally all the genes that controll the ramps are connected to the G of octopus component and one of the conflicting objectives connected to the O of octopus component is the number of instance quelea agents get close.
So the thing I need is to iterate the ramps controling the genes with octopus but activating the boolean toggle (quelea run) each time the ramps are modified so the agents take 40 seconds to perambulate the environment, analyze the instance they get close and let octopus iterate again searching for a optimized environment.

raries by entering %appdata% into the dialog box and browsing to the Grasshopper Libraries folder to find KangarooSolver.dll.)
Oh wow, because of "physics" there is substantial gap between the surface layer of many particles and the inner truss, so we already have some form of boundary adaptive 3D meshing, albeit only in the surface "XY" direction not the normal "Z" direction. There's less full XYZ directional force on the particles at the surface, so they can cluster more there due to the forces from within having to struggle much more against one another from all directions. Something like that.
Differing surface curvature has not much if any affect on particle packing:
The actual physics of electrons along a conductor says they are all on the surface, where they concentrate at sharp features, but here I imagine if they concentrated more at the finger tip, they would then push more interior particles away, which is not very adaptive after all.
Higher falloff exponents than 3 (actually -3) give much more even distances of surface vs. interior, so my color coding by length doesn't even work and there are visibly a lot more interior particles:
I confirm that exponent -2 drives everything to the surface, but also gives a quite odd artifact that they are not minimizing energy by close packing away from each other but are forming squares that seem to align with the UV directions of the container:
Exponent -4 then and even more -5 maximize the interior population, but beyond -5 it it becomes unstable and bounces around like crazy.
The Kangaroo2 custom goal C# script is simple enough:
I'm still confused how to attenuate the effect according to distance to the surface and also curvature of the surface when you are getting close to it since I don't understand if Kangaroo is running the entire Grasshopper script each iteration or not so I could just do calculations via Grasshopper stuff and feed it into the C# script as needed?

giornata inaugurale sarà dedicata alla free-lecture introduttiva finalizzata alla realizzazione di un modello d'architettura complesso attraverso l'utilizzo di comandi e tecniche avanzate di rappresentazione con Grasshopper (plug-in parametrica di Rhinoceros) e 3dsMax. Sarà illustrato inoltre il potenziale di V-ray per 3dsMax realizzando un rendering concettuale. Durante il mini-corso dell' openDAY verranno mostrate le caratteristiche e le potenzialità degli strumenti per far luce sui nuovi valori assunti dalla modellazione 3D. La modellazione 3D sta interessando un pubblico sempre più vasto inserendosi in una nuova fase di ampia disponibilità per conoscenze, software, hardware di prototipazione e modelli. Pur mantenendo tutti i suoi valori già noti la questione si è talmente ampliata fino ad interessare norme giuridiche (diritti sui modelli ,concorrenza con offerte di servizi apparentemente simili, informazioni deformate e onfusione nei media) Makers University[http://www.makersuniversity.com], in collaborazione con parametricart, vi propone un punto di vista ampio e sintetico su queste tematiche.
Al termine della free-lecture, sarà illustrata l'offerta formativa [CLICCA QUI] di parametricart riferita ai corsi che si terranno nei mesi di Gennaio e Febbraio 2013 inseriti all'interno della più ampia programmazione della Makers University. SONO PREVISTE TARIFFE PROMOZIONALI PER COLORO CHE SI ISCRIVERANNO AI CORSI durante l'OpenDAY.
La lezione e la presentazione si terranno nel nuovo spazio co-working il PEDONE.
