Katılımcı listesi 25 ekim salı günü duyurulacaktır. Katılım listesine girenlerin […]

This is done because I needed to represent relationships between different factors and layers of a design process. Although this method of “Chord Diagrams” is a very common technique in information design, it became very hard to find an effective tool for generating those diagrams quickly. There seem to be a solution called “Circos” but however even installing it to the computer became very boring for me. So I decided to make a Grasshopper definition that generates simple circular relationship diagrams. The resulting Grasshopper definition ([GHX: 0.9.0076]) seem to be a […]

This project started as a study on a geometric method, called as quadror, but resulted as an amazing self-standing structure with a capability to fold flat. Initially after Ayza made lots of sketches and models, the project team continued the research and finally they managed to build one prototype only in two days. Here are some photos of this project but there are much more variations and models at their own blog linked below: Below are some photos of their research: This is supposed to be the final prototype. *Students: […]

This final project of the Computation-based Basic Design II at IBU, focuses on the bending performance of wooden plates. Their initial development of a module ended up with a macroform that spans a surface in two directions, enabling various human postures such as sitting, leaning and lying down. A very promising work that could further be developed. Below are some photos: Final prototype The idea and the process. *Students: Azra Tulu Cumur, Batuhan Güllü, Büşra Kılışlı, Cem Mert Şimşek, Fatma Oran, Onurcan Oktay Here is the student blog of this […]
