This is a simple tool resembling John Hejduk and colleagues’ famous design exercise “The Nine-Square Grid”. The tool was developed in 2009 using MaxScript. Here is a phrase from our eCAADe 2009 paper titled: “Role of Studio Exercises in Digital Design Education: Case Study of the Nine-Square Grid”; The nine-square grid is one of the most common kit-of-parts exercises in design studios since more than 50 years. To explain briefly, the ninesquare grid exercise is based on the transformation of a nine-square grid into a series of alternatives, using a pre-defined kit-of-parts and a set […]


From the 2009 eCAADe paper presented with Birgül Çolakoğlu titled; “Designer as Casual Coder: Overview of an Experimental Design Studio”; In recent years, computational approaches in architecture started to change the scope of the architect’s work. He/she is not any more a passive tool user instead, became a casual tool developer. Conventional CAD systems that focus on geometric representation of a designed artifact, are transforming into systems in which the design is represented as a parametric process. By increasing utilization of these systems in architectural design process, arametric modeling is integrated not only as a new medium of design representation, […]


It was 2008, eCAADe Presentation at Antwerp together with Birgül Çolakoğlu and Serkan Uysal. The work presented in this paper, is an example of student work developed in Introduction to Computational Design  graduate course titled “Designing the Design”  at Yildiz Technical University. The course focuses on the use of algorithms as design tools, rather than coding experiments. The course runs parallel to shape grammar course, in which basic concepts of computation is thought through visual design exercises. The shape grammar course teaches rule based logic, algorithmic thinking and formal approach […]


Studio exercises are short term and open ended design activities which represent a constructivist learning approach by limiting design domains. They are student-centered, model and process-oriented educational tools. These qualities make studio exercises potential tools for integration of contemporary Digital Design thinking in architectural education. This research aims to reveal these potentials by defining an analytical perspective and logical connections between the pedagogical intentions of studio exercises and theory of Digital Design. First chapter of this research includes a definition of the research problem. Research method and strategy, along with […]


While looking at the archive, I found this; a recovered model of Süleymaniye from famous Ottoman architect Sinan. It was 2002, a part of my master thesis about the generative system of Sinan mosques (here). In order to understand the specific structural geometry of “baldaken”, I modeled some of the important Sinan mosques in Rhino 3.0, however Süleymaniye was modeled much more detailed in Autocad 2000. Unfortunately I lost some parts of it, the courtyard and minarets. The image shows MAX rendering of the complete version, I’ll upload that version […]


Under the dust of 10 years; revisiting my master thesis; This paper introduces a research about the Computer Aided Instruction (CAI) tool which is based on the master thesis of Tuğrul Yazar from Yıldız Technical University (YTU) Faculty of Architecture Computational Design Graduate Program (BOM). The thesis is named “Expert Systems for Architectural Education: The Expert System of Sinan Mosques” and completed in 2003 under the supervision of Dr. Birgül Çolakoğlu. YTU Department of Computer Engineering supported this research by assigning the graduation project of Ali Murat Akkan as programming the prototype software. The educational […]


This was a couple of weeks ago, together with my six-year old son Mete, we decided to make a “ball” out of old memory cards. I was curious about a subdivision method, using only planar quadrilaterals to construct a sphere (named as Sixty Square Sphere. There are a couple of models on www. Of course look much better than mine :=). However my son was expecting a “ball” to play. Then, both of our expectations have been partially met, I think. You see the component configuration of squares that create triangular […]


In 30th eCAADe Conference, there was a very interesting paper by Gabriel Wurzer and Burak Pak, titled: “Lawnmower”, that explains a research on an educational tool. However, their survey tells us some of the fundamental issues of dataflow programming paradigm for designers. Here is a quote from them; …A further point not connected with the graphical representation is that of lacking comprehensibility of data flow (and therefore the call for step-by-step debugging). Data in Grasshopper is mostly exchanged via lists containing geometrical objects. These lists are used as a replacement for loops, in the following manner: […]


For the last 10 days I’ve been searching for a proper algorithm in representing surfaces using planar shapes. It is obvious that triangulation is an answer but there is an interesting research topic of planar remeshing using shapes other than quads, hexagons or any other regular polygons. Especially in computer graphics, such things refer to optimization of models to decrease the load of GPUs. In Grasshopper community, this has also been discussed and there is a great implementation at Trada pavilion by Ramboll Computational Design Team (link here). There are […]


This is the third and the last project of Infections workshop conducted at YTU this week. Conceptual Framework is developed by Betül Dönmez (DEU). In this project, the host body is infected by high fever and pressure, changes its solid phase into plasma. The solid molecules of the existing body transforms to become plasmatic. This substance can react to various movements around it. When someone comes close to the wall, the plasma molecules start to get into motion, unify, expand, and react to push the existing body itself. This transformation of the […]


This is another final project of the three-day workshop at YTU, named Infections. Conceptual framework is developed by Bahar Aybudak (METU) and Zeynep Gür (ITU). The cellular forms come together to set the existing wall (host body). The wall represents the body structure, in which in case of any infection, various challenges could be seen in parallel with the immune system. The struggle with the mentioned infection is observed through various transformation in these cells. The location in which these transformations occur is not static but changes according to the infected […]


This is one of the three final projects of the Infections workshop at YTU. Conceptual framework is developed by Begüm Aktaş (YTU) and Merve Özhan (BAU). According to them; the existing host body is a 16×11 unit glass brick wall, which is constructed to separate the corridor of the faculty and to create semi-private spaces for various activities. In this project, the host body is considered as a dead tissue of an organism. Sound is considered as an injection that changes the inner structure of the organism and transform the […]
