The A-Chord folding structure was developed and constructed for the World Wood Day 2015 event in İstanbul. The structure had fifty wooden struts of 4 cm X 4cm with changing heights from 200 cm to 230 cm. Two struts joined with a hinge enabled the folding motion of the structure. Thus, the nearby unit is folding in the opposite direction. The Grasshopper model generated all construction details and drawings automatically. As a result, […]

Based on this post, the problem of modeling tree-like fractal shapes is still a good question for the early years of computational design education. Last time, I used Rhino’s macro to study these fractal trees in an “impossibly” limited interface. But this time I used a VB.net script. Here is the code inside of the VB.net component: Here are the inputs. x is the number of iterations. The Crv input is […]

Further studying iteration in Grasshopper, this time, inspired by George Stiny’s “Chinese Ice-Ray Lattice” subdivisions with Aneome, instead of the Hoopsnake add-on I tried in the previous work. As you know, loops add various ways of usage to Grasshopper. In future versions, loops may cease to be just an add-on and become native components of Grasshopper. Until then, loop plugins like Anemone take on this task. In the example here, […]

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 […]

Finally, I had a chance to test and understand the force fields tab in Grasshopper. It creates a continuous vector field inside of a given boundary. Therefore, it is very useful if you want to create an effect of the continuous presence of a force, such as gravity. The Wikipedia definition of a vector field is very basic and understandable: In vector calculus and physics, a vector field is an assignment of a vector to each point […]

This quick project was about a special tiling pattern inside a multi-story residential building’s hallways in Grasshopper. While drawing the construction documents of the project, it was necessary to apply some coding here, as each floor had a different shape to be tiled. Although it is not a real Herringbone tiling, I named it because I couldn’t find a better name yet. First, I’ve imported the geometric boundaries and the “middle curves” […]

Euclidean constructions, when represented computationally, rely on algorithms and mathematical principles to generate geometric shapes and forms. Through precise calculations and logical operations, a computer program can emulate the actions of a compass and straightedge, constructing lines, circles, and polygons with accuracy and efficiency. These digital incarnations of Euclid’s timeless techniques enable the exploration of geometric concepts and the creation of visually captivating representations. This project is interesting because of […]

This is the final Grasshopper sketch of our graduate studio conducted together with Fulya Akipek at Yıldız Technical University Computational Design Unit. The project was about designing parametric “Landscape Extensions” at Kabataş Park. I hope I’ll be able to post the actual student works and the material system, but now; only the final result of the digital sketch we’ve developed together with students is presented here. This was a kind […]

This year’s first semester at 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 “Arboriforms“.  “Arbori-” is derived from the Latin word “arbor,” meaning “tree,” and “-form” indicates a shape or form. Therefore, we can understand “arboriform” as an adjective describing something that is tree-like in appearance, structure, or form. For example, one might […]

Again, we revisited the seamless patterns exercise this semester. This is one of the main exercises of architectural geometry class. We expected to improve students reasoning on generative patterning while they explain their processes step by step. The key element of this exercise is the usage of compass and ruler constructions. However, we didn’t keep this rule limiting their creativity too much. In this activity, we tasked students with developing a personalized […]

This is the Grasshopper definition that generates a tetrahedral helix (also called as Boerdijk-Coxeter helix) but in a funny way. This geometry is also a solution for tangent spheres. I generated the helix using Anemone components for recursion and gave it a little bit of responsiveness. I don’t know if it depends on the speed of your CPU but if it is slow enough, you’ll see the snake game of tetrahedral […]

This is one of the works of the three-day workshop at Eskişehir Anadolu University, called “Animate Patterning“. This project is based on our previous folding experiment posted here, while students advanced it, testing a folding style called “Miura”. They built a 2.5m x 1m folding pattern, explained briefly here. After analyzing, and testing the folding technique, they drew the tessellation composed of a single parallelogram. They joined the structure together with hinges and […]

Inspired by this cut-fold pattern, we developed a prototype with Fulya Akipek. The first experiments were made from 3mm thick foamboards and they worked very well with 50×70 plates. However, when the project gets bigger and bigger, we needed to add a joint detail and use 5mm thick foamboards to achieve our goal (that is to develop a 1m by 2.5m shutter system). Then, we tried to animate its folding behavior by […]

This is one of the ideas we’ve tested for the workshop “Animate Patterning“. Inspired by this work, Apart from the pattern that turns around, the torque, rotation radius and speed of the servo, weight, connection detail, and a number of foamboards become important inputs for this design. In the three-day workshop, one group of students interpreted this idea of using several moving layers and creating an emergent pattern at the […]

This is a Cycloid-like family of curves, generated by its classical description: a rolling circle. I had several other studies on similar topics before. In this cycloid experiment, I used Grasshopper in which, we don’t need to roll the circle. Instead, we can divide a parametric curve, utilizing data lists to simply rotate a circle around it. Finally, evaluating the circle repeatedly creates a Cycloid-like result. I found this as […]

While testing Anemone components for Grasshopper, I accidentally generated these branches by looping. In fact, I was trying to develop the definition that mimics the well-known “Arch SED” component method. This method uses the tangent vectors for the endpoints of the arcs. Then, it iterates the process in a random fashion so that the branches (arcs) join nicely. Anyway, this definition develops new branches from a previous one. It does […]

Here is the video of the project Life Sciences, designed together with Fulya Akipek, and engineered by Filika Interactive. To be presented in the 2014 Vitra Contemporary Architecture Series Exhibition, Life Sciences is an interactive project produced by Filika Interactive using Openframeworks following the conceptual and visual design by Fulya Özsel Alipek and Tuğrul Yazar. The project is an interactive presentation of the content obtained from the interviews made with primary education […]

Lokma is the name of a pastry made of fried dough soaked in sugar syrup or honey and cinnamon, typically shaped into a ring or ball. Unfortunately, it is not the “Lokma” we’ll study here. In Turkish, there is another meaning of the same word related to the history of Eastern architecture. It is the name of metal connectors in railings, mostly inside of the openings of garden walls and […]

This year’s “Lanterns” assignment was nothing short of spectacular. It left both the students and faculty in awe of the creative brilliance displayed. Despite facing constraints in terms of time and experience, the Basic Design students surpassed all expectations. They crafted mesmerizing compositions of polyhedra and intricate unrolled surfaces. Their ability to conceptualize and execute such remarkable lantern designs can be attributed to the valuable skills they honed in their […]

I’ve come across this nice website about the short history of tilings and tessellations. In this post, I am regenerating a tiling of Dürer rhombii. Albrecht Dürer sounds like one of the pioneers of some of the concepts of today’s emerging field of architectural geometry. Here is a phrase from that website about Dürer; “…Like Kepler, regular polygons and polyhedra fascinated Dürer… A large section of the Painter’s Manual is dedicated to […]
