Although it appears simple, Goldberg Polyhedra in Grasshopper became a tough challenge, which I like a lot. I spent about 24 hours attempting to generate these polyhedra. I started with Goldberg’s original method. This creates an equilateral triangle using coordinates denoted as m and n on a hexagonal grid. Then, we place this triangle onto the faces of an icosahedron. Finally, we project them onto a concentric sphere. We can create many polyhedra by changing the values of m and…

The Hilbert Curve is one of the results of David Hilbert’s vision of mathematics as a network of symbolic systems. Defined in 1891, this curve is a fractal that fills a two-dimensional plane with a one-dimensional line in the limit. It exhibits self-similarity. It emerged from representing higher-dimensional spaces through continuous, lower-dimensional entities. A curve that grows within a bounded area remains continuous but non-differentiable. Yet it possesses infinite length. Perhaps no one will ever truly see or fully grasp…

I had been researching Goldberg Polyhedra for a while. While exploring how to perform chamfer operations in Grasshopper, I found some interesting results. I want to share them with you. In this Grasshopper project, I reused my previous work, where I built a dodecahedron using the golden ratio. Essentially, all I did was add the Fillet Edge component. I don’t use this component much, so I learned it through this process. At one point, I realized I had created a…

Robotic EarthCrafts II occurred in the summer of 2024 at Istanbul Bilgi University, seven years after the first. Together with Fulya Özsel Akipek, Nilüfer Kozikoglu, Abdullah Mallah, and Halit Mallah, we experimented with the robotic fabrication of molds for rammed-earth structures. The focus shifted toward a human scale based on the experience gained from Robotic EarthCrafts I. At the workshop’s core were spatial systems resembling muqarnas, which incorporated non-planar geometric transitions. Unlike the first workshop, we utilized a parametric model to design and generate robot…

3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects from a digital file by building them layer by layer. Unlike traditional manufacturing, where the material is cut or molded into shape, 3D printing adds material in successive layers. This allows for greater precision and the creation of complex geometries. In this short tutorial video, I am using Cura software to slice a simple geometry for 3D printing. This is a tutorial for a specific homework…

Relief in the context of art and sculpture refers to a technique where a three-dimensional form is created on a flat surface. The object or figure “protrudes” from the background, creating depth and texture. In this short tutorial video, I am modeling waves relief using the basic drawing and modeling commands of the Rhinoceros software. Here, I use the point surface command. Because, in Rhinoceros, generally we describe the parametric surfaces as four-sided objects. So, this exercise is a basic…

Truchet patterns refer to a set of geometric designs based on simple, repeating shapes, usually tiles or squares. These tiles can be rotated or flipped to create complex and visually interesting patterns. A French mathematician, Michel Truchet introduced these patterns in the 1970s. Since then, you can see them often in art, design, and mathematics. In this short video tutorial, I am modeling truchet relief in Rhinoceros CAD software. My purpose of this modeling process is to demonstrate the basic…

A “hypar” is short for a hyperbolic paraboloid, a double-curved, saddle-shaped surface often used in architecture and structural design due to its unique geometric properties. It is a ruled surface, meaning it can be constructed entirely with straight lines, despite its curved appearance. In this short tutorial video, I am building a beginner-level 3D pattern that resembles the hypar surface. This is a basic drawing exercise to control the viewport and place primitive objects precisely. Thus, more advanced tutorials would…

In art, design, and geometry, folding involves bending or creasing a material, such as paper, fabric, or other flexible materials into defined shapes or patterns. In this short tutorial video, I am modeling a folds relief pattern. This pattern stands out due to its resemblance to a collapsible folding system, combining both structural and aesthetic qualities. We refer to it as a folds relief pattern because it also mimics a relief design, creating light and shadow effects. This video series…

In geometry, a truncated icosidodecahedron, rhombitruncated icosidodecahedron, great rhombicosidodecahedron, omnitruncated dodecahedron, or omnitruncated icosahedron is an Archimedean solid. It is one of thirteen convex, isogonal, non-prismatic solids constructed by two or more types of regular polygon faces. In this short tutorial, I am constructing an irregular truncated icosidodecahedron. It is not the regular Archimedean solid, but a rough approximation of it. I made this model to exercise the exploration of new polyhedra by using rectification and truncation operations. Nevertheless, here…
