ake a network of lines (i.e. a graph) and make a Plankton Mesh, from which you can use Cytoskeleton to make a solid mesh (and then smooth it with Weaverbird).
Works with ngons (polygons with 3 or more sides). Other examples I found only worked with tris and quads.
Works on open or closed surfaces
While these examples start with a surface, you could start with a network of lines and make a patch surface
This is meant for 2D networks/surfaces. I haven't attempted filling a 3D volume. My guess is this wouldn't work as it would require a non-manifold mesh that Plankton wouldn't handle.
Note similar results could be achieved with the following:
TSplines
MeshDual (dual of a tri mesh, not as much freedom/control)
Working backwards, here is the GhPython script from Will Pearson that builds a Plankton Mesh from vertices and faces. The vertices are a list of 3D coordinates, the faces are a tree a lists, with each list containing the indices of vertices that form a closed loop. From Will, "Plankton only handles manifold meshes, i.e. meshes which have a front and a back. This orientation is determined by the "right-hand rule" i.e. if the vertices of a face are ordered counter-clockwise then the face normal will be out of the page/screen."
# V: list of Point3d # F: tree of int
import Grasshopper appdata = Grasshopper.Folders.DefaultAssemblyFolder
import clr clr.AddReferenceToFileAndPath(appdata + "Plankton.dll")
import Plankton
pmesh = Plankton.PlanktonMesh()
for pt in V: pmesh.Vertices.Add(pt.X, pt.Y, pt.Z)
for face in F.Branches: face = list(face)[:-1] pmesh.Faces.AddFace(face)
These vertices and faces are precisely the output from Starling. Starling takes in a list of Polylines which form the (properly oriented) face loops.
The polyline face loops can be generated...
Directly from Panels on a surface using LunchBox
Using any network of lines/curves on a surface (curves will need to be converted to polylines before Starling)
The latter was achieved using the Surface Split command, then converting the face edges (converted to curves) into polyline loops to represent faces.
…
hope this number will grow in future. Currently available features are:
1) Creation of 2d or 3d context for any kind of building related analysis: automatically generate the 2d/3d surrounding buildings for the location where you would like to perform visibility, solar radiation, cfd or any other type of analysis. You need some other plugin for the last three, like Ladybug. It only creates the context=surroundings! The "automatic generation" process also includes creation of the local topography (terrain) along with buildings.
2) Identification of certain 2d or 3d elements in the created context. For example: selection of all hotels, parks, hospitals, restaurants, residential buildings etc.
3) Performing direct terrain analysis (hillshading, slope, ruggedness, roughness, water flow...)
4) Creation of terrain shading masks and horizon files for further solar and photovoltaics analysis.
Gismo will be very grateful if he could get any suggestions, improvements, bug reports and testing in the following period. In case you are willing to provide any of these, the requirements, installation steps and .gh example files can be found here, here and here.
Thank you in advance !!…

we're actually using PET sheets for our flexures. We try to design so that the flexures don't go through more than +/- 30 degrees of deflection. If the angular deflection is kept small, the lifetime can definitely be on the order of 1000000 cycles.
As for the design process (item 2), ideally the designer would be able to use a simple 3D CAD tool to design a model of a robot, and the geometry would be represented by dimensioning the individual parts in the model. Maybe there should be some parametric primitive kinematic building blocks like four bar linkages, box frames, etc. that a user could build up a robot from. But, the key functionality the tool needs to provide is for the designer to be able to visualize how the robot will move when it's fabricated. This could mean observing (or plotting) the motion of a leg, a wing, or a series of body segments. Ideally, then, the tool would generate an unfolding of the design. How this would work is still very vague - maybe the user would assist in the unfolding, maybe there would be an optimization routine that computes optimal unfoldings based on criteria like minimal waste, or fewest pieces (I would *not* constrain the problem to construction from a single monolithic piece as in origami). The biggest problem we have right now, is that our design process is totally divorced from fabrication. Even if we went through the trouble of extruding individual thin plates in Solidworks and creating an assembly for visualizing the kinematics of a mechanism, that particular representation doesn't transfer easily to the fabrication process because it's essentially monolithic.
Item 3: The 2D drawing is simple a drawing done manually in Solidworks. There are different layers for flexure cuts, outline cuts, and potentially any cuts to be made in the plastic flexure layer. Depending on the robot, there may be many separate pieces for different parts and linkages in a single robot. For example, the drawing for a robot containing a fourbar linkage may have the linkage laid out as a physically separate piece consisting of five rigid links connected by four flexure hinges. During assembly, the designer would then fold up that linkage and insert it into the robot wherever it's supposed to go. If you're curious you can see some sample 2D drawings for older designs here: http://robotics.eecs.berkeley.edu/~ronf/Prototype/ under the "Example Structures" heading.
I noticed Kangaroo seems to be a popular choice for physical simulations. I don't really even need to include forces like bending resistance - I'm happy to allow the design tool to approximate flexures as pin joint-type hinges. Once the design is unfolded, the details of how to cut the flexures could be worked out in a post-processing step. I wouldn't expect the tool to be able to realistically simulate the bending of the hinges.
I'm going to have to dig a lot deeper into understanding Grasshopper and Kangaroo. I only just got started with Grasshopper today by following the folding plate tutorial on wa11ace.com.au today. …
to run at full screen. I've gone as far as using an iPad to use as the second monitor via AirDisplay (which actually works really well) but have never been satisfied with any setup that required you to look back and forth as if at a tennis match all day long.
Not long after first using Grasshopper 3+ years ago I've had the desire for a "Live Viewport" component that would allow a live image of the 3d geometry being generated directly in the canvas. Every once in a while I search the forums with the hope of finding a solution, but always come up empty handed. Someday this might exist although for now I have found what might be the next best thing to a native "Live Viewport" component and its enabled with a small app named Sticky Previews. This app uses the task bar preview feature within Windows 7's aero interface to create custom, floating preview windows from any open window currently running. I've only just discovered the app, but it seems to do the trick and has been stable and problem free so far. -- I will post an update if I find out that I might have spoken too soon. The install allows for a 30 day trial and is $15 bucks to purchase. I just found the app and don't know anything about this group that created the app. If you happen to know of them, Id be curious to find out more.

serveral questions:the first thing is in c++ i have to implement more methods than in my c# test project.
they are:
int MyGhComponent::MasterParameterIndex::get(){ return 0;}void MyGhComponent::MasterParameterIndex::set(int index){ }bool MyGhComponent::IsValidMasterParameterIndex::get(){ return 1;}
i found no hint for the implementation of that interfaces. could someone tell me that is correct ?OK, it works, but is it well writen ? What is the MasterParameterIndex?
the second "bigger" problem is, i want to have an output of an pointlist.X y Z 1.2 1.3 1.12.1 5.2 9.2...
my first approch was to use a
void MyGhComponent::RegisterOutputParams(GH_Component::GH_OutputParamManager^ pManager){pManager->Register_PointParam("Coordinate", "XYZ", "Node-Coordinate");}
and
void MyGhComponent::SolveInstance(IGH_DataAccess^ DA){Collections::Generic::List<GH_IO::Types::GH_Point3D>^ pnt = gcnew Collections::Generic::List<GH_IO::Types::GH_Point3D>(); for (int i = 0; i < 10; i++) { GH_IO::Types::GH_Point3D^ point = gcnew GH_IO::Types::GH_Point3D(i, i, i); pnt->Add(i); } DA->SetDataList(3, pnt);}
but this exampel doesn't work...i wirte a small workaround and use the following
pManager->Register_DoubleParam("X-Koordinate", "X", "X"); pManager->Register_DoubleParam("Y-Koordinate", "Y", "Y"); pManager->Register_DoubleParam("Z-Koordinate", "Z", "Z"); Collections::Generic::List<double>^ pntx= gcnew Collections::Generic::List<double>(); Collections::Generic::List<double>^ pnty= gcnew Collections::Generic::List<double>(); Collections::Generic::List<double>^ pntz= gcnew Collections::Generic::List<double>(); ... add .. ect.
this workaround do the job, but i want a better soulution. and i know somewhere out there sould be a better solution. i want to use 3D Points directly in GH without list conversation.
so somebody a familiar with c++ / cli ? and could give me some tipps or a soulution ?
the first thing is: what is the right RegisterOutputParams ?
and witch data type is the right ? Point3d doesn't work. so i try GH_IO::Types::GH_Point3D and Rhino::Geometry::Point3d ...
