Let’s make some nostalgia. I thought of a very simple and useful algorithm that I can generate with Grasshopper. At the concept stage in architectural projects, I tried to derive figures that could symbolize the trees on the land. To make random low poly trees in Grasshopper we need several lists of random numbers first. The Facet Dome component will meet all our needs. In the code I shared on […]

Installation In this episode of Grasshopper for Beginners, we will look at the Interface. If you do not have the Rhino software, you can download the 90-day trial version from www.rhino3d.com and install it. The website will give you the latest version, Rhino 7. The compatibility of the applications and examples with the Rhino 7 version has been checked. Therefore, all applications and examples can run on version 1.0.0007 of […]

Architectural design, as a cognitive activity, has always been fed by architectural knowledge based onpractice and theory, and it has been questioned how creative and generative design processes canbenefit from scientific methods. Therefore, through inquiry and experimentation, the architect develops his or her ideas, constructs and analyzes the space, and continuously improves it. However, this is asubjective process. There are design tools and methods that provide objective criteria for theassessment […]

“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 […]

We continue the Grasshopper for Beginners (2) series with the data flow programming concept. Control flow diagrams we use in traditional programming languages control the sequence of executed commands. In data flow diagrams, the focus is not on the order of commands but on how the data progresses. In the previous example, it doesn’t matter whether the Circle and Polyline command runs first. As a result, both are prerequisites for […]

This is a new series aimed at beginners in Grasshopper. The design method pioneered by Grasshopper with the way he defines geometric relationships is becoming increasingly popular today. Its interactive interface, which looks like a game or a puzzle at first glance may seem easy and its impressive geometric results are a little dazzling. But when you enter the world of Grasshopper, it is understood that it is not a […]

The first trial of Discrete Fourier Transform in Grasshopper and Python. The technique is used to decompose a function into its frequency components. There are many uses for this technique in physics and engineering. However, the interesting and intuitive part of this mathematical technique is the way of its visualization and the potential mathematical “magic” it produces. I found several examples on the internet of this beautiful visualization such as […]

This is the new paper with Meryem Nurefşan Yabanigül, published at Automation in Construction. It is also Meryem’s master’s thesis. This study is about testing the production of curved surfaces with non-linear robotic hotwire cutting and shape memory alloys. Below is the abstract of it: Robotic arms are being used by construction firms and schools of architecture around the world in design/build research and material studies. Some of these studies […]

In this session, I will add two new methods to the Vector class. I think this will finish the basics for the vectors. In the future, we are going to need several new methods like adding multiple vectors and interpolation. But for now, I think this would be sufficient to further advance into parametric curves and surfaces. These new methods will be based on the dot product method we created […]

This is the continuation of the Vector class we started here, and further advanced here, here, and here. This new Rhino Python implementation is mostly educational and partially a hobby. Before this session, we have developed display, magnitude, add, multiply, reverse, and subtract methods. This time, I am adding the vector normalization and dot product methods and seeing the utilizations of the dot product. Line Explanation 1-26 Already explained in […]

This is the continuation of the previous post on parametric curve equations. In this new version, the script picks a NURBS curve from the user. Then, it analyses the curve’s degree and control points. Unfortunately, only the curves with degree+1 number of control points can be processed. In the future, I hope that I will be able to extend this script to include multi-span curves with more than degree +1 […]

Today, I am going to make only one addition to the Vector class we recently started in Rhino Python. The magnitude of a vector can be easily calculated by assuming that the axes (2 or 3 axes) of it are perpendicular to each other. This gives us an opportunity to assume a right triangle visually, and calculate the magnitude (length) of a vector by using the Pythagorean Theorem. In short, […]

The parametric curve equations are good examples to demonstrate the bridge between computer-aided design and mathematics. Although useless and pointless, it is a good exercise to extract the curve equations. In this Rhino Python code, I present a generalized equation extractor for Rhino. Rhino curves are good examples de Casteljau and Bézier curves. You can see the mathematical underpinnings of Rhino curves with this exercise: This code asks the user […]

The SpaceChase plugin for Grasshopper focuses on initiating dynamic capabilities to Space Syntax theory by introducing the “Dynamic Canvas” model along with real-time editing capabilities in an interactive physics-based environment. SpaceChase is a software development project for “Mekan Dizimi Tasarım Uygulaması” under the ARDEB 1001 program of TÜBİTAK. It is a collaborative research project between İstanbul Technical University, İstanbul Bilgi University, and Tuşpa Design Studio. You can find more information about the project […]

This is a new paper published in Nexus Network Journal. I tried to implement euclidean constructions by compass in the approximation of famous parametric curves; Bézier curves, and B-Splines. Then, I created the algorithms to calculate the number of steps on a compass-only construction of Bézier curves. I developed a simple Python script to simulate the geometric constructions. However, I have been studying this topic for nearly four years. In […]

This is the continuation of my new project of re-creating the parametric curve and surface methods of Rhino via Python scripting. If you remember, I started with the building block of vector operations, here and here. Then, I defined vector addition and multiplication, before going deeper into the geometric calculations. In fact, they are using the previously defined addition and multiplication methods. New Vector Operations: Subtraction and Reversing In the […]

Together with Sevde Dinçer, we published a new study on the digital reconstruction of muqarnas. This is also Sevde’s ongoing Ph.D. topic. Previously, she started studying muqarnas geometry in her master thesis under the supervision of Togan Tong. Then, she advanced her studies in this field. Eventually, my contribution to this study was about redefining and comparing the three major modeling approaches. Apart from that, the case study, literature research, […]
