Facade technologies are developing at a more dynamic rate than almost any other issue related to construction today with an impact on performance, sustainability, materials, fabrication, design, delivery and much more. What was once thought impossible is now an everyday reality, and the future promises accelerating change.
Presented by Enclos and The Architect’s Newspaper, COLLABORATION will bring together in a two-day event, the industry, the profession, and the academy to explore the evolution and the issues surrounding today’s high tech building envelope through case studies and lectures presented by foremost
practitioners, as well as panel discussions, and workshops conducted by leaders in the AEC profession.
Aimed at architects, building owners and developers, general contractors, engineers, fabricators, material suppliers, educators, and students, the event’s panels and sessions address the transformative opportunities created by new technologies and resources. From using BIM for communicating effectively with fabricators, to energy modeling, to retrofitting practices and the latest design tools, the COLLABORATION conference offers an unprecedented opportunity to survey the possibilities of designing in the digital age.
Who Should Attend
Architects, designers, engineers, building owners, developers, and facade consultants interested in gaining increased understanding of cutting-edge building envelope technologies.…
a machine that is light and very sturdy. I have taken my Macbook Pro all around the world, carry it with me every day, even dropped it a few times and its still totally fine. Its thin and light.
2) You get some actual support for your hardware even a few years down the line. My Macbook Pro is from 2012 and I can still walk in to any Apple Store and get help with it, which I have done many, many times in different places around the world - I never had to show a receipt or was charged any money for help. There is no PC/Laptop manufacturer in the world with anything close to that, because companies like Asus, Dell, etc. bring out dozens of new versions of laptops every year, so its much harder to service them after a few years.
3) This is the most important one, which usually people forget when they say that Macbooks are overpriced: Resale Value. If you have ever tried to sell an old PC/Laptop (I have a few times), you will know how little value they have even after just 2-3 years. Macbooks retain their value very well and even after 4 years you can still get 50% of your original price.
4) Of course you can install Windows on it and it runs perfectly. I have MacOS and Windows on it and both run absolutely fine. On the Windows side I have Rhino+GH, Maya and a few others. Having Windows is good, because some software still only runs on Windows (looking at you, 3DSMax!). Most other software also runs on MacOS. In the interest of sanity it is great to have an alternative to Windows for all the day to day stuff, like Mail, Calender, Photos, Presentations, etc. that just always works.
5) As for performance: Yes, Macbook Pros dont necessarily have the latest and greatest in graphics cards (the rest is on par with PC laptops), but unless you want to play games you will not need it. VRay RT can do GPU rendering, but you wont get great performance from a Notebook GPU anyways and it doesnt make sense to do rendering on a laptop (especially since you have a workstation). You could get one of the older Macbook Pro Retina Late 2013 or Mid 2014 models with the GTX750M by Nvidia, which will be usable to render using VRay RT, but of course not huge performance. Better to invest in a good used graphics card for your workstation like an Nvdia GTX980ti, which is the best value for money for GPU rendering right now (lots of used ones available).
So at least consider also getting a Macbook Pro. You can buy refurbished models (depending where you are) and they are like new, but a lot cheaper or even get an older one thats used. It will be a worthwile investment.
Take it from someone who has used dozens of PCs and Macs in my lifetime and have to do the IT support here at work (where we also use both).
I still have my Macbook Pro Retina from 2012 and its still running perfectly, super fast, and I can use Rhino and GH for huge files, do GPU Rendering with Octane Render and all sorts of other heavy computing stuff.
Hope that helps.…

he Cordyceps. Maybe some of you find this helpful/useful.
So basically, the Cordyceps is a physical module with 4 knobs and 1 slider. The knobs give an output between 1 and 1000, while the physical slider outputs 0-359. And of course, for this physical module I wrote a plugin to communicate with it. The knobs are intended to be the variables that modifies the design, while the physical slider is intended to be connected to the camera component.
Here I will put up "the recipe" for all to make their own module. You will be able to download the plugin as well.
Please send me a message if you want the 3D-files for the knobs, the box and slider knob. They've been made to directly 3D-print.
Plugin:
https://github.com/zakadjeb/Cordyceps/blob/master/Cordyceps/Cordyce...
Code for Arduino IDE:
https://github.com/zakadjeb/Cordyceps/blob/master/Arduino/_Arduino_...
What you need:
1x - Arduino (Leonardo, UNO or whatever)
4x - Potentiometers
1x - Sliding potentiometer
1x - Breadboard
Bundle of jump wires.
1. So, a potentiometer is a variable resistor, which is basically a component that changes the resistance between the voltage and the ground.
If A is supplied with 5V then B must be connected to Ground. The W will give "read" the resistance, and thus should be placed in Analog input (A0-A5) on the Arduino. The slider potentiometer works the same way.
2. Now connect the 4 pots to each their Analog input. The slider is supposed to be in A4. So to make sure:
A0: Knob1
A1: Knob2
A2: Knob3
A3: Knob4
A4: Slider
3. Now it's time to connect the voltage! Using the breadboard, the voltage can be sent through 1 line, the Ground as well. It should be quite easy to connect them.
4. Now, download the Arduino IDE and copy-paste the code I supplied above. In the IDE, you need to let it know which Arduino you're working with, and which port is should send the script.
5. Almost there. Download the plugin. Open the port you're using through the plugin. Set Start to True and the Cordyceps should be within you.
This recipe will be updated!
Let me know if there are any issues.

I wanted to use it for a client, really I can't since they will freak out about a weird version of Rhino being needed.

What you call trivial is the core of your business, the core of your product, meaning Grasshopper user ability to access serious commands or not. This is, after all, one of the most important commands in the entire Rhino universe. Without it, I have to just completely abandon NURBS and edit meshes since I can't join surfaces smoothly so I have to stop using fragments at all and only meshes afford local detail well compared to single NURBS surfaces. Only polysurfaces can mix in little high UV count blends to deal with tight local detail.
I guess I'll switch to the WIP now. Test that, and just tell clients, hey, that's life. It's not exactly easy to find the WIP download, being a hidden "Serengeti" topic on the main Rhino forum, but I can offer the membership link.

I had to manually install IronPython 2.7.5 too, to fix a broken Python system:
http://ironpython.codeplex.com/releases/view/169382
Now, where on Earth do I find the Rhinocommon manual for Rhino 6 WIP?
I guess it's within the main Rhino EditPythonScript editor, though that can't be searched like a normal manual:
CreateBlendSurface(face0: BrepFace, edge0: BrepEdge, domain0: Interval, rev0: bool, continuity0: BlendContinuity, face1: BrepFace, edge1: BrepEdge, domain1: Interval, rev1: bool, continuity1: BlendContinuity) -> Array[Brep]
Makes a surface blend between two surface edges.
face0: First face to blend from. edge0: First edge to blend from. domain0: The domain of edge0 to use. rev0: If false, edge0 will be used in its natural direction. If true, edge0 will be used in the reversed direction.
continuity0: Continuity for the blend at the start. face1: Second face to blend from. edge1: Second edge to blend from. domain1: The domain of edge1 to use. rev1: If false, edge1 will be used in its natural direction. If true, edge1 will be used in the reversed direction.
continuity1: Continuity for the blend at the start. Returns: Array of Breps if successful.
Now I have normal, productive homework, of figuring out how to specify edges from a Python script.
I'll just sell this extra special capability of Rhino 5 WIP from Grasshopper as a cutting edge advanced new feature other lowly consultants can't match, assuming I can get it to work first.
The initial strategy is to Grasshopper create discrete surfaces, blow holes in a parent surface, scale down and move the little surfaces away, and just blend everything together into a polysurface. Then a client won't freak out so badly when I show them how to use meshes instead, since at least there's an alternative straight from NURBS, that maybe isn't as creatively open ended, but will get them out of a bind if their own client freaks out about meshes converted to NURBS via ZBrush ZRemesher run through T-Splines to get a smooth NURBS polysurface surface that looks like odd patchwork.
Alas, the above Rhinocommon blurb is incomplete, lacking info about what values for continuity are defined as, such as position, tangency, or curvature. I guess I'll just use try numbers.

peuvent se diviser une surface avec ne importe quel motif imaginable. 3. Ici, je fournir un moyen de le faire via Lunchbox ... cela fonctionne mais il est fixe et donc nous avons besoin de jouer avec des arbres de données afin de créer le motif approprié par cas. 4. L'autre composante est un joint C # qui fait beaucoup de choses autres que de diviser ne importe quelle collection de points avec de nombreux modèles (voir le modèle ANDRE que je ai fait pour vous). 5. Vous devez décomposer une polysurface en morceaux afin de travailler sur les subdivisions. 6. Je donne une autre définition ainsi que pourrait agir comme un tutoriel sur la façon de traiter des ensembles de points via des composants de GH standards et des méthodes classiques.
Avertissez si tous ceux-ci apparaissent floue pour vous: Si oui, je pourrais écrire une définition utilisant des composants de GH classiques - mais vous perdrez les variations de motifs de division.
mieux, Peter

as the design table? I think this could be 'drawn' and constrained in Inventor in a lot less time. I know the GH model would have a lot of flexibility, but in this case, what can you do with it that wasn't provided by an Inventor model?
Only the 27 lines mentioned were modeled in Rhino, the rest is modeled with GH.
The 5 hrs involved thinking about the approach, defining vertical lines, tilts, elevations, pitch of the roof, intersections.
Once I had decided what my approach would be, and tested the logic with those first lines, points and data path arrangements, it only took one more hour to get to this:
Which is actually quite fast, compared to MCAD workflows.
If you already have components (columns, beams, etc.) modeled and ready to drop into a project, of course it is lightning fast to model simple projects like this example.
I am not as much interested in those situations, because improving efficiency is straightforward and obvious.
I'm more interested in situations where there are no pre-defined families of objects, in which case you need to start from scratch.
The GH model I'm showing is modeled from scratch, except for the 27 lines in Rhino.
Here's one obvious advantage to modeling with GH, once the definition is set-up, it's virtually effortless to change inputs and alter the overall design. Here's an example, lets say we wanted to extend the roof 3 more units, curling away from the original direction.
Plan view before:
And after:
An MCAD app will also allow you to do this, as long as the location of additional elements follows the existing geometric method of definition. What happens if you want completely change the way you locate columns, roof slope, intersection points?
In MCAD, you'll need to re-model the underlying geometry, which will take the same effort as the first round. In GH, this process is not only much faster, it's open to algorithmic approaches, galapagos, etc. and it just takes some simple re-wiring to have all down-stream elements associate themselves to this new geoemtric definition.
For instance, here's the same definition applied to two curves, which are divided in GH, the resulting points are used as a starting point for lines directed at normal from curves.
This is not so easy to do in MCAD.…

Is millipede not compatible with Rhino version 5? Or is there a different .dll to use?
Having loaded some of the components:
I congratulate you on following Rutten's 3rd law of Grasshopper :)
Although I hope the Solver and especially the Stress lines get further refinement in order to differentiate them as I find it hard to read the small label at the bottom. Maybe the Chimney's can have different numbers 3 = 3D, 2 = 2D etc.

/www.grasshopper3d.com/forum/topics/vb-vs-c-vs-python
http://www.grasshopper3d.com/forum/topics/which-programming-language-should-i-focus-on-vb-or-python
VB.Net and C#
VB.Net and C# both belong to the ".Net" family of languages, and the things you can do with them in Rhino/Grasshopper are nearly 100% equivalent. Grasshopper itself was written in a combination of VB.Net and C#. Some advantages/comments, in no particular order:
Performance - VB.Net and C# scripts tend to execute faster because they are "Just-in-time" compiled as opposed to interpreted.
Autocomplete - both VB.Net and C# have rich autocomplete functionality in their respective script editor components - significantly more so than the python editor. This can be helpful for beginners since you can "hunt" for methods and properties by just typing a "." after an object name and looking at the list of available methods/properties.
Native Component development - If you eventually want to develop GHA assemblies/plug-ins for grasshopper, as of Rhino 5 you will have to use one of these two languages. However, there are plans to introduce python-based plugins in Rhino 6. Even so, the resources around plug-in development are very rich in the C# and VB.Net environments (with c# seeming to be the more popular of the two).
"Strong Typing" - VB.net to some degree, and C# especially, are less "forgiving" languages than python - they require you to know about the data type of the objects you're operating on. This can sometimes result in more verbose code - as you explicitly convert from type to type - but it also promotes good programming practice and helps make errors more understandable.
.Net ecosystem - using a .Net language means you have access to the thousands of libraries publicly available, and the process of referencing these libraries and making use of them is comparatively straightforward relative to python. More on this in the following section.
Resources/Support - At least as of 2012, VB and C# turned up more results on this forum than python, and I think you'll find slightly more expert-level coders in those languages able to help you here.
Which one between the two? C# or VB.Net? - Personally, I greatly prefer C# - I find it to be cleaner and clearer to use. I also have some programming background in C++/Java/Processing so I found the "C family" approach to be more familiar. As David and Damian point out in some of the posts linked above, C# is more popular than either python or VB.net in the rest of the coding world. However, if you are learning without any prior programming experience you may find VB.net to be a bit easier to learn.
Python
Python is, without a doubt, a beautiful and elegant language, which is probably more than can be said for VB.Net/C#. It is very popular with beginner coders, and its syntax is more readily understandable.
Syntax - Python is beautiful to read and write. Its syntax is very clear and free of extraneous punctuation (for example the ";" line endings in c#). It has many very nice language features that make common tasks more concise, like its loop syntax, list comprehensions, list "map" and "filter."
Multiple ways to talk to Rhino/Grasshopper - Python enables two general approaches to interacting with the Rhino/Grasshopper environment: RhinoCommon and RhinoScriptSyntax. If you have prior experience with Rhinoscript, you may find RhinoScriptSyntax to be preferable - it adapts many of the methods you're familiar with to the python language, and simplifies some tasks. A word of caution though - working with Rhinoscriptsyntax can introduce a performance hit relative to RhinoCommon operations. C# and VB.net by contrast can only work with RhinoCommon.
"Goodies" - The Python environment in Grasshopper has some "special features" that the other languages lack. In particular, the "GHPythonLib" library enables the ability to call most Grasshopper components from within your code, and the ability to easily enable parallel processing to improve performance. (A word of caution though - these two features do not seem to "play well" with each other, there may be bugs causing memory leaks that result in increasingly worse performance with each execution).
Cross-Platform - Unlike C#/VB.net, Python can be used natively in Rhino for Windows and Rhino for Mac.
Direct scripting in Rhino - You can also use Python directly in the Rhino environment without the need for Grasshopper if you desire, using the Rhino Python editor.
IronPython / Ecosystem issues - one frustration / potential downside to working with Python for Rhino/GH is that though there is a vast, amazing ecosystem of external libraries for Python, getting these to install/work properly in the Rhino/GH environment can be a real pain - largely because the language is actually "IronPython," a version of python designed to work closely with the .Net ecosystem. Many popular libraries like numpy and scipy are very challenging to get working in Rhino/GH.
Scripting in other programs - Especially in the AEC industry, Python is a popular scripting language for other applications. Tools like Revit, Dynamo, Blender, and ArcGIS all offer their own Python scripting interface - so learning Python in Rhino/GH can give you a leg up in eventually scripting in these other programs.
Python's Stock is Rising - there are currently a number of efforts to improve the "status" of python within the Rhino/GH ecosystem. The python editor in Rhino 6 has a number of improvements, not least of which is the ability to "compile" add-ons for Grasshopper written in python. I'm sure Giulio can speak to other upcoming improvements.
I hope this summary helps you find the right option for you. Ultimately you can't go wrong; concepts from any of the available scripting languages will make it much easier to learn the next one. In my day to day work I use a combination of both C# and python, where appropriate, and I love them both.
I hope others will feel welcome to chime in on this FAQ and add their own thoughts about advantages/disadvantages of these various options! If you have time, read through some of the other posts linked to at the beginning - there's lots of additional great information there. …
