This is a design competition I’m very excited about. Normally, I don’t post such events, but people looking at this blog are probably interested in this. According to the competition brief: This competition is a call for methods and forms that inspire hope and dreams through new technology, creative logic, and aesthetic intuition. Its purpose is to encourage the development of new design methods for better architecture and better cities (and, broadly, better design in general), and to recognize groups and individuals who have taken up this challenge. By introducing outstanding achievements to […]


Basic Design I exercise called “Cut and Fold: Deviation” explores diversity within relationships and material behavior. It is initially intoduced by Salih Küçüktuna as a simple but effective exercise platform. Below are some students works of this one week exercise. The term “deviation” has many uses in a range of fields from medicine to sociology. However it is frequently used in statistics with an interesting evocation to design computing: In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, […]


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 simpliest ways of introducing generative deformations for design geometry.


Here I’ve come across to a nice website about the short history of tilings and tessellations: I’m especially interested in the role of Albrecht Dürer, who seem to pioneer some of the concepts of today’s emerging field of architectural geometry. In this website Kevin Jardine explains mathematical aspects of some of the ancient tilings in a very understandable format. Here is a phrase from his section about Dürer; Like Kepler, Dürer was fascinated with regular polygons and polyhedra, although more for their practical visual possibilities than as the basis for mathematical […]


While looking at the student works of my 2009 class, I realized that in some cases, the “pipe” component takes considerable amount of time to execute even on fast computers. Students mostly create pipes to model structural frame systems such as canopies and facade frames. Therefore, the path of the pipe is usually linear (not curved). I decided to calculate the performances of three approaches the could be used to make pipes in Grasshopper. One was the good old Pipe component, the second was a sweep component with an aligned […]


Below are some student works of this years Architectural Geometry / Pattern Deformations assignment. Students developed their own pattern deformation sequences mostly on regular hyperframes. Based on the classical Parquet Deformation exercise (discussed here), we tried to implement a rule-based approach in order to explore emergent patterns. The exercise seem to reveal endless improvisation potentials. Ece Erdoğdu İdil Side Erdoğan Bengisu Aydos Görkem Ünsal Mısra Sonat Göz Zehra Böhürler


Force fields might be one of the most influential component sets of Grasshopper, thus it also becomes a de facto method like Voronoi subdivision. There are beautiful examples of this mathematical solution on the internet. This time I tried to see how it looks like when animated. Multiple spin forces merged together and the effect of field lines are extended for better visualization. Here is the Grasshopper definition: [GHX:0.9.0061] I know the video sucks. Here are some images of this effect;  


In the third day of Architectural Geometry class, we’ve discussed about the regular tessellations, the famous triangle, hexagon and square tiles. Homework was to develop a custom referential system based on regular tessellations. We used popular explications of Islamic Patterns as inspirational examples, however we developed our own reference systems and patterns.

Here is a simple description of Rhinoceros’ Printing dialog. It is just the same with version 4.0, nothing changed in layout and printing dialogs in 5.0. Especially our Architectural Geometry classes should benefit from this explanation. Most of these options should be tested with plotter (e.g. pencil widths) before final print-outs. Also, you may try creating PDF file of your homeworks from this dialog.


Below are some of the student works from 4th week of this semester’s Basic Design studio. The gestalt notion “figure-ground phenomenon” refers to the characteristic organization of perception into a figure that ‘stands out’ against an undifferentiated background. What is figural at any one moment depends on patterns of sensory stimulation and on the momentary interests of the perceiver. Figure-ground relationship is an important element of the way we organise reality in our awareness, including works of art. Poets may rely on our habitual figure-ground organisations in extra-linguistic reality to […]


This was a month ago, I was searching for a way to work with random points and growing populations. Then this idea appeared accidentally. I wasn’t trying to mimic the behavior of biologic cells (in fact I’m in a serious doubt about biomimicry in general). The trick is to use timer + data recorder + a knob for the arbitrary user input. It starts to breed when you start the timer, but in order to change the evolution speed, just roll the knob!  Of course the knob is as precise […]


I learnt this method from the open math resources website. I couldn’t help myself repeat it in Rhinoceros. It was quite fun to solve circle tangency problems in 2D, this is one of them: drawing the circle that passes three given points, not using ready-made commands but only geometric tools of circle (compass) and ruler (line). Here is the sequence of it: First of all, we need to know that the circle we are looking for is centered at somewhere on the perpendicular paths between the points. This means, we […]


This was the initial example of image processing at our Parametric Modeling class. I saw this design at Maxthreads Architectural Design’s website (especially here). Hand-drawn and digital diagrams can also be digitized and used in order to describe certain parameters for design formation. Such algorithms would similarly use Image Sampler Component of Grasshopper. In the algorithm below, image data is used to capture black pixels as attractors of a Voronoi subdivision. A regular point grid is dispatched according to Brightness values so that the points lie on the lines of the drawing […]


After the first three weeks of research, students at Parametric Modeling course is ready to fire a blog, putting their survey results, ideas and selected example projects around the World. This is the web address so that we’ll be able to check their progress here:
