I am no expert in this field; I would have to do research just like you. Maybe someone else on this forum has already done more work in this area, let's see. Or it might be you, the first one :)
This does not look like something completely at reach for someone with not much programming experience, but maybe with some guidance it could be doable.

>>Do you know other libraries that I can use with it?Sorry I would have to search for other libraries just like you.
EDIT: This link has a simple sine wave written from scratch. It might be a good start to mix with the code above and a playground to understand theory.

This is a standard mesh to nurbs conversion result: http://www.tsplines.com/j/subdtonurbs/MeshToNurbsBoatShell.png
You want to start with a proper mesh reparametrization:
http://www3.cs.stonybrook.edu/~gu/software/RiemannMapper/figures/ti...
Once you have your mesh reparametrized it's relatively easy to divide it into surfaces. That is the easiest approach but it doesn't take into account any features(creases etc)...
This illustrates a nice mesh parametrization with features.

EDIT:
Got a brief look at the Geomagic thingy... seems like it's a subd modeler (like tsplines). Creating nurbs out of subd meshes is easy cause you can basically trace back the subdivision. With Giulios help I was able to make a rough version of that process here: http://www.grasshopper3d.com/forum/topics/skeletal-mesh?commentId=2985220%3AComment%3A558193 ;
(the point is that subd meshes to nurbs are not as much challenging as mesh to nurbs).…
have some spare time please fill in my 3D Printing Open Survey - If you could make almost anything, what would it be ?

ort and export from the images below and also from the HELP file of DB in attachments (Page 71: Importing Geometric Data; Page 78-80: Import 3 - D CAD Data). In their HELP file, they mention about "import geometric data".
However, regarding the input of schedules, loads, constructions and etc., DB normally uses "Component " and "Template" (Page 29: Templates And Components; Page 591: Templates; Page 533: Components). "Templates" are databases of typical generic data, including Activity templates, Construction templates, Glazing templates, Facade templates, HVAC templates, Location Templates, and etc. "Component " are databases of individual data items (e.g. a construction type, material, window pane).
Both "Component " and "Template" are allowed to be imported and exported by using "Import / Export library data" command (.ddf format - DB Database File; Page 734: Import Components/Templates, Export Components/Templates). DB also allows us to build up our own libraries of templates and components (Page 731: Library Management; Page 733: Template Library Management).
In order to import both geometric information and other information related to schedules, loads, constructions and etc. from GH to BD, we supposed the following two ways:
1. GH(HB+GB) --> gbXML (both geometric and "Component " and "Template" information) --> DB
This is the way we most prefer. We did see information related to schedules, loads, constructions encoded in the gbXML file generated by GB, but still do not know the reason why DB did not take this information (I also mentioned this in Q6 within the gh file). We assume this might because the gbXML file we create encodes the schedules based on a different template / schema than the one DB expects. We also post this question to the DB forum for help.
(http://www.designbuilder.co.uk/component/option,com_forum/Itemid,25/page,viewtopic/p,13755/#13755)
2. GH(HB+GB) --> gbXML (geometric information only) + .ddf ("Component " and "Template" information only) --> DB
If the first way doesn't work and DB only takes geometric information from the gbXML, then we might think of the other way - generating the .ddf files from GH(HB+GB) to pass the schedule, load and construction information to DB.
I was wondering if it is feasible for HB and GB to have this function? And what is your suggestion to achieve this?
In addition, we notice that DB can export XML files (not gbXML), so we are trying to figure out if DB also accepts / reads the XML file. If so, we might be able to convert the gbXML (with both geometric and schedule information) to XML. What do you think about that?
Thank you again for all your help!
Best,

" (idiomatic) and easy way of doing things.So here come some basic questions:
Is there a way to create custom components by grouping an existing sub-network together? I'm looking for a way to re-use parts of a program (something similar to subroutines), and to make the network look less cluttered. I found that it is possible to group components (ctrl-g), but this still displays them as separate blocks (too much clutter), and provides no way to re-use a sub-network in such a way that if it is modified in one place, all it's instances (all the places where it is re-used) also get modified.
Is there a component that does nothing, just passes a signal through? Suppose I need to connect block A to blocks B1, B2, B3 (all three get the same input). Then I change my mind, and I decide to connect block C to these three, not A. In this case it will be necessary to change three connections, not just one. I'm looking for an easy way to do this by a single rewiring, not three. (This came up in a practical situation).
Finally, a related question: is there a component that acts as a switch, so I can choose which signal it passes through out of a possible set of choices? For example, suppose that a set of objects can be coloured based on a number of different properties (size, positions, rotation, etc.) I'm looking for a way to switch between these very easily, without the need to do much rewiring.
Thank you in advance for any replies / useful comments, even general ones on how to easily structure a large Grasshopper program/network.…
limate based sky, and then use that sky to do a radiation analysis with ambient calculations turned off (i.e. a -ab 0 run).
Daysim approximates the position of the sun, which can be in as many as unique 3000 locations on an annual basis, to only 65 odd locations in the sky. GencumulativeSky, which is used for the cumulative studies in the Hydra examples, takes the annual radiation data and creates a Tregenza Sky pattern .... While a Tregenza pattern might be fine for an annual simulation, using it for hourly simulations isn't going to be very accurate.
There are actually some thermal comfort examples on the Hydra website that you might find useful.

lies on gradient-free optimization algorithms, delivering fast and deterministic results. At every run, goat will yield the same optimal result.
goat is a drop-in replacement for galapagos. It is based on David Rutten's galapagos GUI and interfaces NLopt, a collection of mathematical optimization libraries.

For getting started with optimization in parametric modelling environments in general and with goat in special, check out our presentation slides on Geometry and Optimization with several comprehensive examples.
Once you are familiar with the basics of optimization, head over to our comprehensive documentation on goat's different configuration options.…
bursts of calcium which interacts with a photoprotein to create flashes of light.
In the Pacific Canada Pavilion gallery at the Vancouver Aquarium, the public can excite origami jellies into creating beautiful patterns of colour and light using a touch screen controller.
When left alone, free from human intervention, the origami jellies instinctively react to each other. Random, generative displays of drifting coloured glow are triggered, not unlike jellies in their natural environment.
Jelly Swarm overhangs the gallery space. The soft, coloured light emitted by the jellies reflects on the aluminum surface. Viewed from below, the visual effect evokes looking up to the ocean's surface from undersea.
The installation features 94 origami jellies, folded in Tyvek. Each jelly contains its own RGB LED module. The 472ft² hanging surface was custom designed in 3D and fabricated from 6061T6 aluminum. Water jet cut and anodized on both sides, it comprises 154 generated triangles and 430 connector pieces.
Programed as self-contained objects capable of interacting with their closest neighbours, the Jelly LED modules are interrupted only by external intervention - the public engaging with the small display interface. Data is sent from an AIR app to each LED module via mbed wirelessly.
