other kind of planes because I need to deal with Display Pipline .
There's a few threads about similar problem( i'm posting them here as a reference)
1. Viewport rectangle
2. TextTag parallel to Viewport
3. Horster method (with timer)
4. Another horster method to get On screen display (also with timer)
5. Discussion how to send Rhino Viewport Cplane to GH
There is a lot of things possible to do using camera frustum plane such as:
- making custom project layout
- Camera-plane sections
- 3d Isovist (example of Francois)
- projections on the frustum plane
I need to output geometry to Grasshopper in order to use a Frustum Plane for dynamic operations like for example: On Screen Display of Text Tags with sections and other views.

About your question regarding the Tutte graph drawing algorithm (also known as topological embedding):
The Tutte algorithm can be viewed as a special case of Spectral Graph Drawing, which is a mathematical solution for topological embedding formulated as an optimization problem. The formulation of the topological embedding (e.g. as in Tutte algorithm) is in fact quite similar to the so-called force-directed drawing that is often solved by heuristic methods like the one we have made for the SYNTACTIC plugin. You can read more about Force-Directed Graph Drawing (a.k.a. coin-graph drawing and kissing disks drawing) and Spectral Graph Drawing and Spectral Graph Theory in my dissertation.
The functionality of the Tutte algorithm is only guaranteed for graphs that are 3-connected, i.e. graphs with more than 3 vertices which cannot be torn apart unless at least two vertices are removed.
https://en.wikipedia.org/wiki/K-vertex-connected_graph
Speaking of the conditions for the Tutte algorithm to work properly: Practically, this implies, for instance, that there should not be rooms connected only to one other room.
Anyhow, long story short, we have decided to continue with Spectral Graph Drawing and 3D force-directed graph drawing. These algorithms are ready and with a couple of adjustments for maximum speed and stability we will release them shortly. Some conditions for these algorithms are easier to ensure, but in general if a node(room) is connected to only one space or the graph is not well connected one cannot expect a good graph drawing from neither of these methods. The other issue that is also common is that the force directed graph drawing will not work if one forces a big bubble to be squeezed in the middle of smaller bubbles. Stay tuned. …

1. Cluster rollover tips
Id like to be able to create rollover help text for each cluster input. This could be a right click thing once the cluster is created or something specified before creating the cluster (a string input for the cluster input arrows?)
2. Disconnect all outgoing
I'd like to be able to right click on an output of any component and disconnect all wires coming out of it.
3. Disconnect all selected
It would be cool if you could disconnect all incoming or outgoing wires from all currently selected components (instead of just one at a time).
4. List item dynamic slider
There has been a lot of discussion about dynamic range sliders and the issues that they would cause. Id like one specifically for list item selection. This would be an integer slider that would have a range of 0 to the list length-1. If the range remaps and the previous value is no longer available, I think it's best to have the current value stay as close to the previous value as possible.
5. Cluster slider/toggle inputs
I think it could be valuable to cluster a series of variable inputs (like sliders or toggles) to make a sort of options cluster. In this case you could just have a list of sliders and toggles each connected directly to a cluster output arrow, select all and create your cluster. This would be great with the value list component as well.
6. Have a component that could output the x and y location of actual components on the canvas relative to the top left corner... Not sure exactly what you could do with this but I think someone could do something interesting with it.
7. 3d MD slider. I see the option is greyed out and don't see a way to activate it... Still under development? Seems like it could be just like the color picker. Would be cool.
That's all I can think of right now. I'm sure there will be more to come in the future.
Feel free to comment.

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.…
sinergetici associati alla compresenza simultanea di differenti strumenti di analisi e digital design all'interno di un processo di progettazione in svolgimento. I partecipanti utilizzeranno Grasshopper (modellatore parametrico per Rhino): l'uso di questo editor grafico di algoritmi si integra alla perfezione con gli strumenti di modellazione di Rhinoceros 3D espandendo le possibilità di corstruire modelli parametrici altamente complessi. Per generare una complessità simile saranno utilizzati collegamenti live ai diversi programmi elencati di seguito: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI Durante questi intensi 3 giorni, i partecipanti impareranno il workflow dei plug-ins con l'aiuto di esempi esplorando una panoramica dei differenti software, le possibilità di testare le performances di un progetto o l'uso di strumenti addizionali non legati ad un singolo sistema (es. accentuazione, formazione, reazione parametrica) [english text] The focus of the workshop is to integrate and correlate the synergistic effect associated with simultaneous presence of different digital design- and analysis tools in an ongoing design process. The main attention is set on easy to handle interface , which should be used at a early stage of conceptual design to respond to external and internal influences in a intelligent and sustainable way. Participants will use the software Grasshopper as a parametric modeling plug-in for Rhino. The usage of this graphical algorithm editor tightly integrated with Rhino's 3-D modeling tools open up the possibility to construct highly parametrical complex models. To generate this complexity we will use live linkages to several programs listed below: . Autodesk Ecotect Analysis via GECO . FEA software GSA via SSI In this 3 intense days, the participants should learn the workflow of the plug-ins with the help of examples and get an overview of the different software's, there possibilities for evaluating the performance of a design or the usage of additional tools to be not chained to a single system .

Public spaces have been for a while the periphery of our daily life. We will explore in this workshop how we can manipulate and alter people’s perception and direct their attention to how these spaces are integral for city life. This exploration will be backed up by intensive technical tutorials introducing computational design and fabrication techniques and tools mainly Rhino, Grasshopper, Geco and Ecotect. Not only will this be the typical technical workshop, but rather you will also have the chance to be guided step by step on how these tools are used through out different design stages in a real world scenario. Design prototypes will be produced through 3D printing, the main workshop output will be a fabricated one to one functional model for one of the designs using our new in-house CNC machine.

ow..
It's basically using a 3d framework to define points on the framework and then interpolate curves through them.
Right now Im assuming that I merely translated something incorrectly early in the script that lead to most of the definition issues later on...?? It also seems I am not using the append function correctly... :(
If anybody well versed could take a look it would be awesome... :)

Computational couture looks at the creation of exclusive custom-fitted clothing (typical of haute couture) through the lens of a systemic approach, extending the sartorial techniques with 3D modeling and computation-based approaches developed in Rhinoceros and the visual programming environment Grasshopper.
Aim of the workshop is to exert, infuse and expand the sartorial sensibilities to body proportions and dress making into an algorithmic approach that loops through design and fabrication by means of laser cutting and 3d printing for the design and production of a garment. Participants will be divided in teams focusing on specific aspects of the garment related to the production technique (laser cutting or 3D printing).
