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. + +IMAGE + +IMAGE + +IMAGE + +##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. + +* [Tutorial 1](https://vimeo.com/372876664) +* [Tutorial 2](https://vimeo.com/372895793) +* [Tutorial 3](https://vimeo.com/373176432) + + +<iframe width="560" height="315" src="https://www.youtube.com/embed/EexonaUZhxs?rel=0&controls=0&showinfo=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> + +<iframe width="560" height="315" src="https://www.youtube.com/embed/JnrGAdoXsy4?rel=0&controls=0&showinfo=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> + +<iframe width="560" height="315" src="https://www.youtube.com/embed/179EzWVsEAY?rel=0&controls=0&showinfo=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> + +<iframe width="560" height="315" src="https://www.youtube.com/embed/rufBrcaMdgI?rel=0&controls=0&showinfo=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> + + +###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 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.

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.
