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]


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 […]


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: […]


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].


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.


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 […]


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 […]


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 […]


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 […]


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 […]


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 […]


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, […]


This is an unfinished research on textile tensegrity technique, developed at Basic Design I Studio of Istanbul Bilgi University. The result was not satisfactory  as a design outcome, but yet interesting educational experiment. Students explain their project as follows: Coral reefs and corals themselves were starting points of our research. After analysing some of the coral forms and a couple of studio sessions, we came up with experiments of using “textile tensegrity” in our designs. We got inspired by many examples of this technique; the portable basketball stadium in London, the Temporary […]


This project explains itself very well, their motivation was very different from the rest of the studio; In our Basic Design Final Project, we are inspired from Theo Jansen’s Strandbeest sculptures, and we wanted to make our arboriform kinetic. First, we made a copy model of the original kinetic sculpture for ourselves in order to observe its shape, parameters and movement patterns. We realised that the system can also move and generate interesting variations without actually “walking”. So, we decided to study from the smallest components to the whole system and produced the Dna […]


Student project of the first year Computation-based Basic Design I studio at İstanbul Bilgi University Faculty of Architecture. The contextual background is based on “Arboriform” that aimed to drive students’ design research process. Here is a quote from the student’s presentation: …Many of us do not believe and even do not want to believe in compatibility of natural phenomena with things done by human. Nature eliminates unfitted environmental factors while generating new potentialities from it. In our project, “symbiosis”, “tropism”, “branching”, “holding”, “rooting” etc. were the concepts that helped us to construct our material research. We aimed […]


This year’s first semester Basic Design studio was full of surprises. Together with Can Sucuoğlu and Birgül Çolakoğlu, we coordinated 9 student groups in their 4-week final project called as “Arboriforms”. Here is the material research of the first group of students. They described their project as; By using the folding geometries, we managed to mimic the movement of an ivy. It is the symbiotic relationship between a tree and ivy via haptotropism and branchings. We connect the folded and pinned faces of aluminium mesh plate, creating our micro-component. Then arranging micro-components together, we […]


This is a macro exercise in Rhino, showing that Rhino is pretty much capable of automating some cool text effects. Just copy and paste below code into the command bar of the Rhino, or open macro editor by typing macroedit, then paste there and press play. You’ll enter any string when prompted, then the macro handles rest of the process. You can play with the parameters by changing numeric values you see in the macro. ! _show _selall _delete _-text 0,0,0 h 10 _pause _sellast _setobjectname tex _boundingbox o c […]
