ons, variations, and "cross-breeds" of consumer electronics product designs, for example, telephones:
Or for example, to generate and populate control panels with parametric variations of knobs, dials, etc.:
I've been reading up a bit on procedural/generative modelling, shape grammars, etc. But the first basic problem I've run into, is that all the devices I'm interested in generating have filleted edges, and I've read that Grasshopper can't do that, because the FilletEdge command is not exposed in the SDK. I did read however that in Rhino 6, fillets will have history - so I wonder if that opens it up to Grasshopper at some point in the (hopefully not too far) future? Or is there some other approach that would help in generating these kind of forms in Grasshopper?
I guess most people doing this kind of generative modelling for CG/games would use Houdini or 3DS Max, but I want to be able to actually build some of these things with 3D printing/CNC, so I think I would be better off in the NURBS/solids world? I also looked at Solidworks/Inventor, which do very well with parametric fillets, but it seems like it would be difficult to get them to do the kind of generative stuff that Grasshopper can do, fooling around with Excel spreadsheets and formulas. Unless I missed some kind of Grasshopper-like plugin or scripting system for them?
Anyway, comments appreciated. I can imagine Grasshopper being quite useful for industrial design concept exploration, surprised that I haven't seen more of it...

2. WORKSHOP (23-27 April 2014)
A 5 day Design-Based Research Workshop exploring new techniques in Digital Architecture/Fabrication, with a specific focus on the use of generative systems and parametric modeling as tools for creative expression.
Our ultimate goal is to increasing the efficiency of utilizing digital tools in parallel with geometric performance of the primitive design agent.
+ + CONCEPT
Fashion and Architecture are both based on basic life necessities – clothing and shelter.
However, they are also forms of self-expression – for both creators and consumers.
Both fashion and architecture affect our emotional being in many ways.
The agenda of this workshop is to investigate on the overlap between these two areas of design, art & fashion.
Fashion and architecture express ideas of personal, social and cultural identity, reflecting the concerns of the user and the ambition of the age. Their relationship is a symbiotic one and throughout history, clothing and buildings have echoed each other in form and appearance. This only seems natural as they not only share the primary function of providing shelter and protection for the body, but also because they both create space and volume out of flat, two-dimensional materials.
While they have much in common, they are also intrinsically different – address the human scale, but the proportions, sizes and shapes differ enormously.
+ + + OBJECTIVES
So far, Architects have been using techniques such as folding, bending etc. to create space, structural roofs or different other structural shapes.
The agenda of this workshop goes further with the investigation of algorithmic thinking through generative tools Integrated in design.
The challenge is creating a bridge that connects these two areas of design, architecture and fashion that perform at two opposite scales.
+ + + + TECHNICAL BRIEF
In the early stages physical models and low-tech strategies will be used, allowing the participants to gain a greater understanding of materials, fabrication and assembly methods as well as simple, yet pragmatic structural solutions.
Later in the workshop these strategies will be digitalized and elaborated using software visualizing tools such as Rhinoceros and the algorithmic plug-in Grasshopper.…
his comes in the form of an HTML page with links to every component, so you will need to view it in your web browser. (I use Chrome and it doesn't seem to be working correctly, but when opened in IE its fine.)
2) Included in each help topic for each component is the Inputs and Outputs descriptions and data types.
3) You supply the data. What you supply and how you supply it is for you to decide. There are umpteen different ways. Are you asking for a list of those ways for each input?
4) Points can either be Rhino objects or 3D co-ordinates. To create a point you can use any of these methods, but it mostly comes down to user preference. I like using Panels as this displays outside of the component.
5) Because of the nature of vectors they represent magnitude and direction but they don't have an independent location, so there is a component that will display vectors in Rhino.
6) The user.
7) There is a Primer on the front page. Here you find the Basics, but because GH is ever evolving in its current beta state you might find things that aren't relevant any more or simply don't work the same. And here is the reason why nobody is writing an update because it could be soon out of date.
8) Importing images by either dragging them from explorer onto the canvas or right click context menu Image...
9) Single line = Single Item of Data. Double line = Multiple items of data on the same Branch. Dashed Double Line = Multiple Data on Multiple Branches.
10) User preference
11) Toolbar management is probably the bane of David's life. Most things are logically placed. For example the Curve Tab, Primitives are any simple curve types that you are creating from scratch. Similarly Splines is for more complex curve types created from scratch. Analysis is where you find components that are finding answers supplied by curves, control points, curvature, parameters, end points etc. Division is a subset of this category but has a group of its own. And Utilities is where you find curve related actions that you want to perform, offsetting, rebuilding projecting, exploding etc.
12) I would image it would have been the Point On Curve component in Curve>Analysis. Why that group? You are not putting a point on a curve you are analysing a curve for the location of a point based on some parameters that you are supplying. For example "what is the mid point?"
I hope this goes some way towards answering you questions. No doubt this will have generated more so don't be afraid to ask, it took me several releases of Explicit History (aka Grasshopper) before I realised what the egg did, it never occurred to me that I could put my objects into Rhino when I was finished. Or the fact that I could use panels to 'see' data outputs.
Al the best,

step-sizes. It starts out with large jumps, then as it cools the jumps get smaller and smaller as does the likelihood of a retrograde jump being accepted as a valid new state.
Most fitness landscapes have more than one dimension and therefore a 'jump' could include any number between 1 and N, where N is the dimensionality of the landscape. The Drift Rate setting —which may well be poorly named— controls the odds that a jump includes an additional dimension. All jumps must be at least one-dimensional, but 25 percent of them (on average) will include another dimension. 25% of those will include a third dimension and 25 percent of those a fourth and so on and so forth until the dimensionality of the landscape has been reached. Here's a list for 1000 jumps:
Drift Rate: 25%
1D jumps: 750
2D jumps: 187
3D jumps: 47
4D jumps: 12
5D jumps: 3
6D jumps: 1
A good question to ask would be; "Why would you want a jump to include more than one dimension?" and the answer is that the more genes are related, the higher the changes that a multi-dimensional jump will yield an improvement. It's not difficult to imagine that you cannot improve your current state by only modifying a single gene. Sometimes you need to change two in unison in order to reach a better solution. If your genes are highly related (which is bad practice to begin with) then you may need to adjust the Drift Rate to a higher value.

make sure I add this information to groundTerrain_ inputs in the next few days.
So if you are using "Gismo Terrain Generator" component (former "Ladybug Terrain Generator 2" component), only the following types are allowed for groundTerrain_ input: type_ = 2 (surface with rectangular edges)
type_ = 3 (surface with circular edges)If you are using "Ladybug Terrain Generator" component, then only the:
type_ = 1 (surface with rectangular edges)
is allowed.
As for terrain not being colored when it is created as a surface, you can analyse it additionally with "Terrain Analysis" component for Elevation analysis type. It can even be colored for rendering afterwards by using the "OSM Render Mesh" component. Check the attached file below.Have in mind that in urban areas "Ladybug Terrain Generator" component produces much more precise terrain than "Gismo Terrain Generator" component. On the other hand, the latter component can generate much larger terrain areas (up to 10 000 sq km2, at least in theory).
The reason why component might still work even though a terrain mesh has been added to the groundTerrain_ input is probably because once groundTerrain_ input fails to convert a mesh to a brep, this results in it being equal to None. Component then considers as if groundTerrain_ input is empty and runs as if nothing has been added to it (the buildings are laid down on a flat plane with 0,0,0 as the plane origin).
Thank you once again for all the testing you are doing!!! It really makes Gismo a better plugin!!…

ng the "kaleidocycle" as a facade component, and i need to be able to move it through its entire "rotation" in 3d space to understand where and how it is moving.
http://www.youtube.com/watch?v=4owFczeqqMQ
this is what it is doing, in general. there are 2 sets of 3 hinges, rotated 180 degrees, making up a hexagonal form.
here is a rhino model of the form. i used the trigonometric properties of the isoceles triangle to make this model very accurate (63.333, 53.333, 63.333 angles), and now i need to describe the movement.
It is TOUGH. i think i have it and it just throws me for a loop (no pun intended).
I have a ghx model set up to where it can go through part of the cycle, but the inbetween states are incorrect, and therefore it's not valid, but it shows how something like this could work. The trick is it rotates on multiple axes at different times, and its just very very tricky to figure out what it is rotating around and when.
If anyone has any ideas, or insight, please please let me know. I am working on this in my masters' studies, and I'm pretty screwed if i can't figure this out in grasshopper!
Also, please find attached a research article concerning this form. I haven't been able to apply the geometric findings of theirs, yet. But it shows it can be described mathematically.
THANK YOU!!!!

ts connectors and slots that allow CNC machining the facets and connectors for assembly.
https://www.youtube.com/watch?v=34OvgflJEmI
We developed this construction methodology earlier this year while working on a large scale parametric structure for Midburn, the Israeli Burning Man. While doing so I used grasshopper to generate the facets for the geometry, while a friend on the team (Matan Zohar) wrote a javascript app that translated the mesh into connectors and slots for CNC manufacturing. You can see more about the project here:
http://www.shlomimir.com/triped/
I wrote this component as an exercise in learning rhinoscript and python, with the purpose of bringing the functionality into the grasshopper workflow. It's now to the point where it is working for triangle and square welded meshes while outputting the connectors and slots as an unorganized list.
Questions and To Do List
1. I'm new to object oriented coding and functions, and basically just wrote the whole thing as a series of conditional loops with two dimensional arrays holding the data. Planning on restructuring this better, would love any tips.
2. Right now outputting the connectors and slots on the input mesh itself in 3D, planning on setting this up layed out on one plane to organize for cutting. I was wondering if there are any existing tools for this or if I need to do this manually.
3. Labeling connectors and slots. Is there anyway to output text from python that can be later baked into the rhino for labeling?…

hacia donde crecerán las venas, y tenemos otro conjunto de puntos 'N' que son los que forman el patrón de venas.
1. Por cada 's' perteneciente a S, buscamos el 'n' perteneciente a N más cercano. Ese 'n' va a "moverse".
2. Por cada 'n' que se mueve, hacemos un vector dirigido a todos los 's' hacia los que se mueve.
3. Calculamos el vector medio de todos los vectores del paso 2, movemos 'n' con ese vector y lo añadimos a V.
4. Si algún 's' está muy cerca de algún 'n', ese 's' se elimina.
5. Se repite el proceso.
Esto es para formar venaciones abiertas sin autocrecimiento (como la siguiente imagen, hecho con Visual Basic).
Para las cerradas (las reticuladas que forman algo como células, como en la imagen tuya), el paso 1 y 4 son distintos y no sabría decirte cómo hacerlo. En ese pdf explica un método usando delaunay pero es muy lento, además gh no tiene ese algoritmo en 3d (entonces solo se podría hacer este patrón en 2d), por lo que estoy buscando otras vías, solo he logrado llegar a esto:
Es más complicado de lo que parece.
No obstante, si te conformas con menos, hay muchas formas de crear raíces y patrones similares, con SortestWalk, Anemone, etc... Hay ejemplos en este foro.
Si realmente quieres conseguir ese patrón, deberías aprender a programar porque para añadir distintos radios a las venas es necesario que las venas tengan topología y eso se complica demasiado desde gh. Nervous System para su "Hyphae" usó C++ con la librería CGAL, que es una muy poderosa librería de algoritmos de 3d.

rent actors to work together in real time on an architectural project.
DixieVR was born from the idea that virtual reality could become a fantastic tool for architecture and architects, not only for virtual tours but for the conception at its very core. Inspired by the efficiency of sandbox games, DixieVR will allow you to build a fully parametric 3D model from scratch in a very intuitive way and to simulate various factors like natural and artificial light, gravity, and more. DixieVR is also multi-user oriented : several people, architects or not, are able to work together in real time on the same 3D model and in the same shared immersive environment !
The project started in the Digital Knowledge department of Paris-Malaquais Architecture School.
The DixieVR Softwares can be found here : dixievr.github.io
// Interoperability
DixieVR deals with .dix files. For more information about this file format, please refer to the Interoperability documentation of DixieVR.
You can use this DixieIO plugin for Grasshopper/Rhinoceros for exchanging data between DixieVR (PC) & DixieViewer (Android).
You can import or export objects at any time inside a DixieVR scene. The Software also come with a library of premade objects that you might find useful. Adding your own premade objects to this library might be a good habit.
If you are hosting a scene, you also have the choice to open a .dix file directly from the main menu, this will load the last scene in which the geometry has been saved.
// Plugin
The DixieVR Plugin can be found in the Extra tab, come with 3 components and a example definition:
Dixie2Gh : Import DixieVR geometry to Grasshopper/Rhinoceros reading a .dix file (up to 1000 beams and/or 750 faces).
G2D_Polylines : Export Grasshopper/Rhinoceros Polylines to DixieVR writing a .dix file (up to 1000 line segments).
G2D_Mesh : Export Grasshopper/Rhinoceros Mesh to DixieVR writing a .dix file (up to 750 triangulated faces).
To install:
In Grasshopper, choose File > Special Folders > Components folder. Place the DixieIO_01.gha file there.
Right-click the file > Properties > make sure there is no "blocked" text.
Restart Rhinoceros or Unload Grasshopper.
