About to finish the well-defined section of this year’s Parametric Modeling course, here are the mid-term questions I’ve asked; First question checks if the curve < > point conversions are well understood in Grasshopper. Evaluating a parametric curve and generating closest point from another curve. This also requires a basic understanding on the use of Grasshopper interface. Second question was testing a basic and classical use of attractors on grids of objects. Students generated their own grids and put pyramids on each cell, as the height of these pyramids would […]

This is a great site, explaining very familiar concepts of dataflow diagrams for designers from the first hand. Leveling is an interesting chapter there, I’m not sure if it completely fits with the use of “Clusters” in Grasshopper but it is obvious that the complex systems should be well organized not only to be perceptually “better” ones but also to develop a way to use parts of definitions again and again in diffierent situations. …How do you actually DO the leveling of DFDs? The discussion thus far has been misleading in […]

    Site models could be calculated for laser cut easily using Grasshopper’s native components. This definition was a practical one we’ve created in Parametric Modeling course to see that Grasshopper could also be utilized to prepare fabrication documents not generating design outcomes. However this definition is a draft one and could be improved more by putting labels inside of each cut pieces, trimming the edges properly and so on. It is good news for students at least that they have a chance to generate topography models from the AutoCAD maps […]

2015_03_26-delsurf-th

This is a useful tip both to solve some of the problems with custom surface subdivisions, and to explain the uses of parametric surface evaluations (the U,V,W thing) and the practical use of data lists. Step 1: Put your points inside 0,0,0 and 1,1,0 so that the resulting coordinates can easily be converted to U and Vs. In the example, we are putting some random points between 0,0 and 1,1 using Populate2d component. Step 2: Then make whatever you want with these points. For example we can create voronoi subdivision or delaunay […]

2015_03_17-metalfoam-th

Image Sampler of Grasshopper saves life, if used responsibly. While explaining the component to this year’s ARCH362 students, I used this simple example that generates numbers from a beautiful picture of “metal foam” and uses it to generate lots of circles: Metal foams are lightweight but stong materials, that are typically produced by injecting gas into the liquid metal. Of course it becomes easier to teach something when you manage attract the attention of students. Here is the Grasshopper definition that shows the basic use of image sampler component: [GHX: 0.9.0076]

Finally I had a chance to test and understand what the “vector force” stands for in Grasshopper. It creates a continuous flow of force inside of the boundary, and is very useful if you want to create a field that is under continuous presence of a directional force such as gravity. The definition is pretty much simple: [GHX: 0.9.0076] [3DM: Rhino 5]

2015_03_17-cakma-th

Another tutorial we’ve analysed together with ARCH362 students last week was the one that mimics Zaha Hadid’s Kartal Masterplan. Although the project of Zaha Hadid was pretty much controversial among Turkey’s architectural critics (and most of the people also), we’re not dealing with how successful of “ugly” it is, but the most simple version of the technique that generated such forms. We have a term “çakma” in Turkish that means “conscious imitation, possibly full of errors”. But however, this “çakma Kartal Project” example has a pedagogical intention that a technique or concept could […]

2015_03_17-fields1-th

This year’s Parametric Modeling class starts with some of the very basic use of Grasshopper concepts. This definition is a practical start-up of using force fields in architectural design process. However it does not compute any physical phenomena (such as circulation of people, wind or anything else), but shows a simple way to tell Grasshopper about walls that push the field, and points that pull the field. I’ll post more of these kind of basics, hopefully along with some student works. Here is the Grasshopper definition [GHX: 0.9.0076] and the dummy Rhino file [3DM: […]

2015_03_16-contouring-th

After this tutorial, we are still working on the basic ways of making contouring easier in Grasshopper. This is the updated version of the 2-year old contouring definition in Grasshopper, with some additional functionality. It produces a flat and properly numbered output of each section. However it does not include optimized nesting to reduce material use. Here is the Grasshopper definition (don’t left click, use right click and “save” option) [GHX: 0.9.0076] and the Rhino test file [3DM: Rhino 5].

2015_03_07-gaudi-th

Gaudi-like columns are generated as part of the “boolean” classes of Design Computing. The most inspiring, beautiful and ugly variations are often done by boolean intersection, as this operation is the surprising one of the three brothers. While the class deals with the concept of emergence once again via solid and void relationships, constructive solid modeling techniques are introduced. Although it is widely used as a spatial analysis approach in architecture, there are some examples of using boolean algebra in actual design processes. CSG trees are one of the interesting […]

This video is dedicated to the Design Computing and Basic Design students, who “contour” and then move each and every section by hand, one by one, in order to fabricate their laser-cut homeworks from cardboard. It could also be a macro but I prefer this because it somehow does not work in all conditions. Maybe you should orient your contouring results similar to shown in the video, and then use shear command to spread them.

2015_03_07-wood-th

This is a project proposal designed at the workshop organized together with Simge Esin Orhun and Fulya Akipek as part of the International Wood Day Exhibition in İstanbul. This time, the final Grasshopper definition is created “after” some experiments with physical models. Here is the first model showing the idea inspired from the folding chairs studied here. I realized that in order to make a “wall” instead of a chair, it would be a good idea to extend the edges of the sticks so that they meet at several (2 for example) […]

This quick project was a mapping of a tiling pattern inside of a multi-storey residential building’s hallways. While drawing the construction documents, it was necessary to apply of some coding here, as each floor had a different shape to be tiled. First, I’ve imported the geometric boundaries and the “middle curves” of the designed tiling pattern. The design was a simple one, yet to be handled carefully. After solving an example like this one, the Grasshopper definition generated all tiling solutions for the remaining hallways very quickly, saving lots of time. Sorry for the spaghetti code here, […]

Classical folding methods were subjects to be tested and studied in this semester’s design geometry classes. This has been very useful in introducing first year students with 3d euclidean constructions and using physical objects as reference to a digital model. Groups of students studied different folding methods and made both physical and digital models. Two of these methods were dominant in the class however, one of them was the variations of Miura-Ori, and the other one was Ron Resch’s famous folding pattern. Below are some models students made during their research. I’ll […]

2015_02_01-foldchair-th

Parametric variations of the folding chair, inspired from the “Rising Chair”, designed by Robert van Embricqs, was a good exercise for me to study Grasshopper again. After several different solutions, I’ve found the shortest one I think. This definition could work alone without any Rhino data, the overall size (width, length) of the plate, number of longitudinal cuts are all calculated within the definition. Without using any physical engines for complex rigid folding simulations, this is solved quickly just by applying simple right triangle equations. There are three other parameters that control the shape […]

2015_02_01-lex-th

This is the final Grasshopper sketch of our graduate studio conducted together with Fulya Akipek at Yıldız Technical University Computational Design Unit. The project wa about to design parametric “Lanscape Extensions” at Kabataş Park. I hope I’ll be able to post the actual student works, the material system, but now; only the final result of the digital sketch we’ve developed together with students are presented here. This was a kind of “sketchy” definition that came up as an investigation about how can we construct a system on the selected area […]

2015_01_29-group8-th

This is our last material system of 2014, designed and produced at Basic Design I studio section instructed together with Can Sucuoğlu and Birgül Çolakoğlu. This group of students succeeded in developing a flexible but strong connection detail that allowed them to generate desired macroform quickly. However the overall look of the final composition should have been much better, it was placed in a little hurry, due to the snow and heavy rains. However, the multi-layered research on material, fabrication, connection details and geometry were very interesting. Students: Aslı Naz Çolakoğlu, Büşra […]

2015_01_24-group7-th

This was an example of high concentration. Group of students developed a material system from a very weak connection detail, making it possible to stand by itself, purely by experimentation. In the beginning, the geometric composition was already decided, so their research focused more on the possbility and precision of the materials and the connection details in realization of the composition. While watching a documentary film about arboriforms in nature, we gathered different project proposals, and decided to focus on the very first meaning of arbiforms which was highly related with the […]

2015_01_24-group6-th

This student project was lightweight but also very strong, a good start for a research on fibrous structures. The group of first year Basic Design students explain their project as; Arboriform, meaning as “something tree-shaped” was the main theme of the project, however we decided to focus more on the entwining movement of ivy. In order to create a material system that reflects this entwining behavior, we chose to research on fibrous structures, specifically the pvc hoses. It was a challenge to understand how we could make a very weak material such […]

2015_01_24-group3-th

This research was very successful in achieving its intended physical performance, which was holding on to a tree its designed for (and even  near climbing up in some cases). The system is lightweight yet very powerful, holding on but not causing any harm to its “host body”, the tree. The group of students explain their project as; Commensalism is one of the symbiotic life forms, in which one of the two life forms live together and provide benefit while the other one neither provides benefit nor gets harmed. For example, […]
