 # 8. Computational couture
 
+This week I produced some printed results, but I mainly spent a lot of time documenting what I learned from the tutorials I did, to build up a vocabulary or archive of useful *clusters* that represent a functionality or method. A bit like a function in programming I guess? Once I have a good overview of these it will be a bit easier to start doing my own designs/scripts by using them as building blocks. Screenshots of these annotated blocks allow me to quickly look at how stuff is done without having to go all the way into Rhino & Grasshopper (it gets a bit slow :D)
+
+**"Tangible" Results**
+
+Besides the documentation below, I also tried out some designs by printing them on textile. I worked with the image sampler to create some shallow surfaces consisting of separate geometries. They would fall apart if printed in the usual way, but printing them on textile holds them together. Sizing is a bit of a trial and error still. These samples are useful to try out how small you can go without elements just falling off. I printed these with an Ultimaker 3, using PLA, and Cura as a slicer.

+##Tutorial time
+
+Designing parametrically takes quite a different shift in thinking about shapes and designing. I have done simple parametric design using Eagle (for electronics production), Processing and very basic parametric 3D design using Fusion360. Rhino+Grasshopper definitely allows for super beautiful architectural forms and patterns. But I found out quickly that it's quite hard because it takes quite an abstract mathematical approach to shapes and relationships. This doesn't come naturally per se, so I decided to do loads of tutorials to get a grip on it and maybe tweak a few to understand the design to fabrication process.

+**Plug-ins and user objects**
+
+Get your plugin on here: https://www.food4rhino.com/
+I used bifocals as recommended by Eugenio. 
+
+And also used the *remap+* user object that is used a lot by the Parametric House guy. 
+
+###Tutorials with Eugenio Bettucchi (Noumena)
+
+Eugenio guided us through some basics in Grasshopper, such as the interface, using fields with attractors and repulsors and all sorts of components and useful methods to link things together.

+###Tutorials by Parametric House
+
+I also enjoyed a lot the tutorials by Parametric House! They don't just show how to build up a design, but also explain the logics behind it, which is reaaaally helpful at this beginners stage. I saved them in a [Youtube Playlist](https://www.youtube.com/playlist?list=PLXJnjBsCdBxHFOV1te8BiZnfz9LF7mpHT) for later reference. 
+
+**Rotating curve**
+
+Pretty nice beginner tutorial this one [here](https://www.youtube.com/watch?v=iXYMQh1Z_r4&list=PLXJnjBsCdBxHFOV1te8BiZnfz9LF7mpHT&index=9&t=0s).

+
+**Geometric Pattern**
+
+[This tutorial](https://www.youtube.com/watch?v=n_bZJjkkkG8&list=PLXJnjBsCdBxHFOV1te8BiZnfz9LF7mpHT&index=3&t=0s) was great for creating tile-like patterns like the one I made below. I was not successfull in creating a printable design yet! I have to study the parameters a little better to understand how I can avoid making crazy intersecting lines and end up with curves that an be offset and extruded. But good start and lots of playing around.

+[This Truchet Tiles tutorial](https://www.youtube.com/watch?v=DIc7a2mectY&list=PLXJnjBsCdBxHFOV1te8BiZnfz9LF7mpHT&index=4&t=0s) was also a super nice one.

+**Pattern using Booleans & Dispatch**
+
+[This one here](https://www.youtube.com/watch?v=Cs2YzNyQuiU&list=PLXJnjBsCdBxHFOV1te8BiZnfz9LF7mpHT&index=5&t=0s) explains an easy way to generate patterns using **dispatch** and **booleans**. 
+
+Here's the overview, and below a video of some slider action:

+
+**Graft, Flatten, Simplify, Parametrize**
+
+You have to do quite some data management to organize and merge lists and groups of data well in a way that can be translated to geometry but this is so abstract, it's not easy to understand the why and how. This video does a great job at exaplaining why and when you should use these.

+
+Here it is also explained in a tutorial file I made following the lecture by Eugenio, that shows the difference in a different way.

+
+**MD Slider**
+
+I find the MD slider very useful! You can use it to represent an area or surface in percentages (x: 0 to 1 and y: 0 to 1), which is also referred to as UV values. Oki cool. Some components only take UV values like that (so not absolute points relative to an origin, but points relative to the size of an area expressed in percentage. The image sampler also uses UV values for example.

+
+**Image sampler**
+
+This is an [image sampler tutorial](https://www.youtube.com/watch?v=9RvgvPw6kxo&list=PLXJnjBsCdBxHFOV1te8BiZnfz9LF7mpHT&index=11&t=0s) that allows you to use simple images to create geometry. I used this to print some of my samples.

+##Inspiration
+
+**Auxetic structures and metastructures**
+
+You can cleverly engineer materials so the change states in a way. Oh that is so cool! Bea found a file somewhere from somebody who made them. I'd like to explore this further. Especially for textiles it's interesting because they can really shift shape and SIZE! 
+
+[This article](https://issuu.com/danielvr81/docs/out_of_plane_pages_09.14.2015) describes some of the process behind developing the designs for these, and the theory. A bit dense but very interesting ideas there. I wish I had spent more time studying math and physics though, if only then I'd known how interesting the applications of such knowledge would be!

+##Lecture notes
 What is computational design? A series of [automated] instruction carried out in a specific order (also definition of *scripting*). Hmmm this is debatable if you ask somebody with a humanities background. 
 
 Alberti: instructions for a building. Forms into numbers and instructions forfabrication.
