Kündekâri is an old woodworking technique, composed of interlocking parts without any glue or nail. It is primarily used in wooden doors and minbers inside Mosques. The interlocking system makes the whole structure very durable. I tried to model this technique using the Voronoi pattern, naming it Voronoi Kündekâri. Below you see a typical example of Kündekâri pieces and the resulting pattern. The interesting part of the Grasshopper model is to define the tongue-and-groove detail. It is similar to a…

This is based on my failure of creating an optimum solution for planar polygonal subdivisions. There is a method called Tangent Plane Intersection (TPI), explained briefly here (sometimes similar algorithms are called “planar remeshing” and  “variational shape approximation”) which is effectively used in the Trada pavilion (here). I tried to implement a similar method using only native Grasshopper components and no recursion, but it quickly became much more complicated than I thought. It was based on the simple idea that…

Below is a classical Truchet Patterns example we used to discuss in design computing class. Now, we can create a much faster and cleaner definition using the newly added Array component. The new version of Grasshopper brings several important features: Patch surfaces and date/time components. We used to implement a VB component to create simple clocks that measure temporal operations in Grasshopper. Parsing and executing MusicXML and related applications were based on that. Now I see there is a whole…

The story of Atatürk Cultural Center (in Turkish: Atatürk Kültür Merkezi – AKM) dates back to the 1930s. Auguste Perret designed the first version of the project and started the construction in the late ’30s. However, war and financial problems halted the construction. The project continued in the early 1950s with major updates and extensions. Faruk Akçer and Rüknettin Güney were responsible for this second version. Hayati Tabanlıoğlu designed the last version of the building. He studied the previous version…

The Parquet Deformation exercise is generally originated with William Huff. Huff conducted it at several schools of architecture since the 1960s. Huff defines the exercise as rooted in two analytical disciplines; monohedral tilings in geometry, and the continuous deformations in biological morphology. This is generally exemplified by D’Arcy Thompson’s and Albrecht Dürer’s studies. One of the student’s works of Huff, Trifoliolate is a single-axis, single-prototile hexagonal parquet deformation. It was designed by Glen Paris at the studio of William Huff…

I’ve seen beautiful examples of similar compositions made using vector field components in Grasshopper. I just tried to make my own animate field lines to see how they float over force dynamics. In essence, these compositions could also be done using regular vector components but the field components make life much easier by merging different forces together rather quickly. As you see below, it is a quite small definition that creates beautiful complexity. Although we know every single parameter of a…

WFC Shangai is a design exercise in our first-year Design Computing class introduced by Onur Yüce Gün. This exercise emphasizes both analytical thinking and associative geometry and aims to utilize boolean operations as solid and void references in creating forms. We asked students to develop variations of this building. In order to discuss this formation in class, I studied a simple algorithm to test variations in real-time. The initial shape, developed by a boolean intersection of a rectangular prism and…

This is a first-year design computing problem we studied last month. It is a simple parametric wall exercise introduced by Mete Tüneri. Creating a simple definition of a building brick to be placed on a straight path, and then manipulating the path to reform different variations of the brick. This aims to introduce a fundamental concept of associativity in contemporary architectural geometry and design computing. Students are then encouraged to develop their own parametric brick to be tested in different…

Today’s design computing class was about fractals. In Rhino, writing macro statements are very easy to learn as it just mimics your behaviors in a sequential text. There are a few syntactic rules that we should know. First, you should watch the command line carefully to understand the steps of your design process. Each command in Rhino requires different inputs from the user. In macro, you may enter these values or tell the macro to ask the user by typing…

Maxscipt can be used to automate specific modeling tasks in a sequential-parametric way. This example, developed in 2005 shows an example of that. It creates various table designs by polygon modeling operations and asks the user various parameters. Below is the interface of the script; There are preset parameters in a dropdown box, and all other available parameters are organized in rollouts. Here are some default results of the script. It is not as fast and smart as the Grasshopper…
