Here are the variations of classical six-pointed star patterns generated by Grasshopper. Generally, you can see these patterns under the title “Islamic patterns” because they are frequent in the decorations of mosques and palaces. I studied these patterns in Grasshopper earlier in these posts. I always find this an interesting geometry exercise. This time, my main goal was to develop a useful code only with the native Grasshopper components that create laser-cut-ready products of hexagonal star lattice. Thus, I made…

I am still trying to find the simplest solution to some geometric definitions. This is why I called this Grasshopper definition “Basic Grid Deformation”. Here you see the Curve Proximity (CrvProx) component in use. This component calculated the shortest distance between two curves. I think the underpinnings of this component are very interesting. I hope I can code it in Python one day. In order to see the result more clearly, the Previews of the Interpolate Curve (IntCrv) and Square…

In this short tutorial, I want to give Grasshopper beginners the basics of how we create attractor systems. The Grasshopper definition you see in the below figure is the equivalent of array-type copying operations in CAD. However, unlike in CAD programs, here we are dealing with multiple generations of objects rather than transformations. Attractor Basics: Data Matching In the application you see in the figure below, each row of the hexagonal grid created with HexGrid has a different radius value….

This project was about a unique 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. The problem statement included one sketch with a zigzag-shaped tiling pattern. Thus, I tried to implement this pattern on multiple floors with different shapes. I call this definition corridor tiling. First, I’ve imported the geometric boundaries and the…

This is the continuation of a very old parametric model of a building facade, presented here. I will introduce the basic Grasshopper definitions of several alternative designs. The first one is the rhombus facade. The first part of the algorithm deals with the necessary data collection. We reference a polyline from the Rhino model as the path that the facade will follow. After that, we create vertical lines around the path. Then, we shatter these lines by using a Graph…

This is my first experiment on developing add-ons for Grasshopper. There are two components in the “Parquet Deformations” add-on. These are the ghuser files coded in Python. So, they can work by just dragging and dropping to the Grasshopper canvas. These first two components of the toolset are more like helpers while designing Parquet Deformations. I introduced some of my re-generations of classical parquet deformations here and here and in a book chapter here. The Loft Component of Parquet Deformations…

This is the continuation of the physical prototyping project of a folding pattern from 9 years ago. I simulate the folding pattern using the Rhino Grasshopper Kangaroo. As seen in the video, this is possible thanks to the pre-set hinge positions on the Rhino model. Thus, the folding motion can be animated on the screen. You can download and try the Grasshopper code. I often use this code in my ARCH 362 Parametric Modeling course. I think it is possible…

The Parquet Deformation named “Wiry Wonder” was designed by Michael Cuttita in William Huff’s studio at the State University of New York in 1989. The below figure shows the original drawing made by the student. Similar to the previous one, this composition is based on a hexagonal lattice. In this composition there are three significant prototiles, marking the three key moments in the shape-shifting process. There is also one invisible prototile. It accommodates the transition between the last two prototiles….

“Strange Start Startling Stop” was designed by Mary Purdy at the State University of New York in 1985. The composition is based on a hexagonal lattice (above figure). There are four prototiles, marking the four key moments in the shape-shifting process. The first prototile is a regular hexagon, which is also the first tile of the composition. This prototile morphs into a shape that is a composition of four smaller hexagons, creating the second prototile. This morphing process finishes at…

I will try to explain the student project called KUKABAE that was developed in my Robotic Fabrication elective course in 2018. This was a very interesting project. Initially, the students were doing the design to attach an ordinary pen holder to the robot. but then the project changed by chance. they decided to replace a pen holder with a ceramic knife. As seen in the video and pictures, the relationship between the material and the instrument became more complicated and…
