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 […]

Here, our aim is to generate a 3D Voronoi puzzle ready for 3D printing. Below is the step-by-step explanation of this Grasshopper algorithm: The 3D Voronoi Puzzle Step number one is the application we saw earlier in the Voronoi diagrams. We obtain random polyhedra within a given volume quickly. The basic features we need for the puzzle are: (1) When we solve the puzzle the final volume should be a […]

Here is a tattoo design I am currently developing by using Grasshopper. 11 years ago, I developed a Grasshopper definition that approximates Julia Sets here. One of the experimental outputs of that definition looks suitable for a tattoo design. It is a beautiful fractal shape. But I am not perfectly sure about its suitability for a tattoo. Here it is: This was generated by the function z2+c and the parameters […]

This is a basic Grasshopper exercise, covering many fundamental topics. The aim is to create the parametric model of a spiral staircase. This is more educational than functional, I guess. Below is the explanation of the Grasshopper definition in three parts. Helix Points for the Spiral Staircase In the first part of the definition, I am defining the points ordered on a helix. First, I calculate the number of steps […]

This website explains the problem and several solutions. I managed to implement the formulas to convert a 2D square grid into spherical coordinates. The Fibonacci Sphere is one of the solutions to the equal distribution of points on a sphere. It is not the best solution to this problem. But it is regarded as a quick and efficient one. Suitable for me. I developed this Grasshopper code by studying the […]

This is an implementation of the famous Koch Snowflake Fractal in Grasshopper. We will be using the Anemone add-on to handle the iterations. In this fractal, we start from an equilateral triangle. Then, we form new equilateral triangles, one-third of the side. So that each repetition protrudes in the middle of all the sides. In summary;1: Take a closed polygon and divide it into parts and divide each side into […]

I studied the interlocking joint details in Grasshopper here and here. This time, the interlocking structures were revisited with a cleaner code and an in-depth explanation. I believe that this is a very good educational exercise for learning the potential of the native Grasshopper components. The Preparations The Region Difference (RDiff) component is used to create the interlocking detail of a surface that is contoured with bi-directional spacing. In the […]

In this Voronoi puzzle exercise, we derive two-dimensional puzzles by using Voronoi diagrams. This is similar to my previous studies here, and here. Part 1: The Random Voronoi Diagram In section 1 of the below image, I use a rectangular region to generate random points. Then, I create a standard Voronoi diagram by using those points. Finally, I explode the Voronoi cells. Part 2: The Voronoi Puzzle Details In the […]

Fields is a native group of components available since the very early version of Grasshopper. In today’s Design Computing class, we studied it again with the first-year design students. I studied these interesting and beautiful shapes earlier here, here, here, and here. The one you see below is a short in-class exercise about vector fields. The exercise aims to show the Grasshopper’s capabilities in form-finding studies via Field Lines. The […]

This is a return to the Swirly Flames tutorial I made in 2013 here. Since then, Photoshop changed a bit. There is no more Variations tool. Therefore, I had to use other tools such as Color Balance, Hue/Saturation, Inverse, etc. to achieve the same effect. It is still cool for me, personally, although we are in the age of AI-generated images now. It is not the visual result only, but […]

This paper investigates the integration of robotic fabrication into first-year undergraduate design education, particularly in a basic design studio. Traditionally, robotic technologies are not introduced at this level due to perceived skill gaps among novice students. The study demonstrates the potential and strategies for incorporating robotic arms into early design education through an experiment conducted at Istanbul Bilgi University. The experiment involved 32 students from various design disciplines, divided into […]

While digging through the lecture archive, I found this video I made in 2017. We introduce Platonic solids and Archimedean solids in the Design Geometry course at Istanbul Bilgi University. This video shows how we can create an Archimedean solid, the Truncated Tetrahedron, by folding it from a flat sheet.While doing this, I intersected the spheres by using the relations between the side lengths of the solid, and I calculated […]

We continue with the Grasshopper for Beginners series by explaining Rhino+Gh workflow principles. What does GH add to Rhino‘s standard drawing and modeling functions? To put the question differently, what does GH do that conventional modeling programs, such as Rhino, can’t? What is the difference and relationship between Rhino+Gh? Let’s take an example to answer these questions. Our example is about parametrically describing a surface model and deriving its alternatives. […]

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 […]

Let’s continue the Grasshopper for Beginners series. We start with the traditional “Hello World!” displayed on the Rhino screen: Placing the Components In most CAD programs, the text creation function, which is the equivalent of the Text command, is performed by a component called Text Tag (Tag) in GH. The Text Tag (Tag) component is in the Dimension panel under the Display tab. If you’re not comfortable with tabs and […]

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 […]

Here is the Grasshopper implementation of the famous Evolution Door design by Klemens Torggler. The code I used here is from my course on Parametric Modeling. This Grasshopper algorithm is a good exercise for the basics of Kangaroo. I attached several goal objects to a special mesh object created in Rhinoceros. Kangaroo’s goal objects work as expected to simulate the folding door behavior. I used the goal objects to fix […]
