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 […]

We are back! Here are some Revit components I’ve created for a project. These and other cool downloads can be found at revitcity.com T_Room Tag T_Parking Space T_Door Tag A Door
Third and the final outcome of the Animate Patterning workshop is coordinated by Mehmet Ali. Students tried to develop a kirigami-like surface animation (which is also a good solution to my one-servo question) while they studies numerous variations. They ended up with this panel, ready to be moved by Arduino; The workshop is organized together with Mehmet Ali Altın and Fulya Akipek. Students are, Murat Akırmak, Gizem Ceyhanlıer, Cem Kıyak, […]
Here is another student project from the three-day workshop we conducted together with Fulya Akipek and Mehmet Ali Altın. Briefly, the idea was to develop a system of cogwheels that spin together to animate an entire pattern. It was about to develop a kinetic system with a simple Arduino-based setup, probably with one servo and a motion sensor. The integration of the cogwheels system and the underlying pattern was interesting […]
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 […]
It seems that our first-year students of architecture, interior design, and industrial design take Rhino’s macro functionality very seriously. This encourages us to study algorithmic techniques more and more in the freshman year Design Computing class. Below are some of the results of this week’s assignment. They explicated the modeling process of their prototiles into macro codes, ready to be molded. Zeynep Dutipek developed the macro to reconstruct her prototile with different parameters. She […]
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 simple Grasshopper definition [GHX: 0.9.0072] that activates Rhinoceros’ camera by given parameters. Camera position is determined by the “point-oriented” method here. This means that you have to have a target point for the camera first. In fact, I was trying to find a suitable command for getting the actual camera position of the Rhinoceros but I think it is impossible (for now). I couldn’t track the camera object by its […]
It is Baldequin (or Baldachin) in English, Baldeken, or Baldöken in Turkish. I don’t know which one is correct, but it is the name of a structural system of arches and pendentives that carry a dome. Sinan experimented with square, hexagonal, and octagonal variations in his mosque designs (as I developed parametric definitions of them in my 2003 master thesis (here)). Today, together with students we’ve modeled the system and […]
I’ve been searching for a way to implement edge bundling on Grasshopper. It is an effective visualization technique that you can use in connectivity diagrams. There are a couple of different approaches to this problem. It is a nice way to analyze common paths within crowded graphs. I’ve found several entries in the Grasshopper blog about this subject, but only implementing Kangaroo seemed to be a complete solution. My approach […]
Anemone is a simple but effective plug-in for Grasshopper that enables loops. It has been a while since Hoopsnake succeeded in extending the dataflow capacities of Grasshopper with recursion. However, Anemone is much more user-friendly and easy to use. Below is my first test, yes it works! Here is the group page on Grasshopper. I hope this plug-in would be advanced more. I’ll try to return to my old studies […]
Here is a test of the optical flow component of Firefly. You can check the Firefly add-on to Grasshopper here. As an ongoing research project, I’ve been searching for a suitable platform to study responsive geometric patterns. This initial study focuses on one particular effect of Firefly, the optical flow that outputs the direction vectors on a given webcam input. I developed traces of it by joining endpoints of these […]
Currently, Rhinoceros does not offer the capability for an aligned text onto a curve, to the best of my knowledge. However, Grasshopper, with its latest version, provides a solution for such tasks by offering a range of text components. For my current project, I am studying an installation. It incorporates various typographic effects, and Grasshopper has become an invaluable tool in this regard. Nevertheless, it is important to note that […]
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 […]
In this fun experiment, points rock and roll! It should be based on a sound input of course but this is only a test to see if I can handle a timer and graph input at the same time. I’ll modify this definition to actuate with sound. The use of the timer component gives a certain degree of randomness to the overall formation. Here is a video of the Headbanging Points […]
Bending is an easy operation in Rhino and Rhinoscript, however, Grasshopper did not include that particular transformation (along with cage editing) yet. I tried to simulate the bending transformation by using native Grasshopper components. First, surface projections and pulls did not work at all, because I wanted to simulate a real bending effect without changing the surface area or edge lengths. Then, the Surface Morph component seemed to handle this […]
In today’s drawing class, we taught methods of drawing basic transformations by hand. Mirror was one interesting subject of that. However, then I opened Grasshopper and Rhino to test the effects of curved mirror planes. Unfortunately, I realized that there is already a curved mirror component in Grasshopper :( Here is the Grasshopper definition: [GHX: 0.9.0061] This might be one of the simplest ways of introducing generative deformations for design […]
