This Grasshopper exercise is a special one. I used Hoopsnake components to develop the branching design I studied earlier here. This time I multiplied the number and orientations of several tree structures to generate my interpretation of the Tree of Life. The challenging part of the algorithm was to finalize every branch tangent to a predefined circle. Group 3 handles this issue by utilizing a Blend Curve component. There are […]

Here is a short tutorial on getting help from Grasshopper in physical terrain modeling. It is a classical architectural terrain modeling process. Let’s see how Grasshopper can help us with this. Part 1: Terrain modeling for Laser cutter The terrain model entered in the Brep data store in this application is a closed/solid model. For now, you can also use ready-made components such as Cone or Sphere (Sph) to quickly […]

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 […]

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 […]

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 […]

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 […]

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 […]

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. […]

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 […]

In this 5th episode of Grasshopper for Beginners, the interface continued by exploring the interface of Grasshopper. With the help of these two methods (tabs and search box), we can find the components. We can select them with the left click and place them on the canvas with the left click again. Now take random components and try to place them on the canvas with both methods. Therefore, components with […]

In this fourth episode of Grasshopper for Beginners, the explanation of the graphical user interface continued. We call the data flow diagrams definitions. GH definitions are rendered on a large blank screen area called canvas. We can zoom in and out (zoom) the canvas with the middle mouse wheel. Or pan sideways by holding down the right mouse button. Tabs and panels are menus where all the components of the […]

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 […]

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 […]

Here is a design exercise I’ve been giving to students. It aims to familiarize students with the concept of dataflow diagrams used in Grasshopper. Dataflow is a different concept than conventional computer programming. Here is a good comparison between control flow and dataflow languages. In most educational settings (such as courses and workshops) we concentrate on the fundamental issue of dataflow management via design projects. This requires us to think […]

Today in the Digital Fabrication course, we examined digital-physical translations utilizing the robots add-on for Grasshopper. Students learn how to get coordinate data from a physical environment, use it in the digital model and apply it to a robot motion. We aimed to dig chopsticks into an EPS block by using a special wooden tool called “Chopstick Digger”. In the first hour of the class, we attached the “pointer” tool, […]

Today, we started learning Robots add-on for Grasshopper. The first two codes we experimented with were similar to the first week’s jogging exercises. In the first one called “axial jogging”, we had 6 number sliders to control the angles of the axes. Every number slider generates values between -Pi and +Pi. These numbers are joined into a text by adding a comma in between. Then, Create program and Simulate Program […]

Here is a short series of videos showing the basic usage of Ladybug tools in a canopy design. So, I prepared this for my Parametric Design Systems elective course. Then, I encouraged my students to design their own canopies utilizing a similar Ladybug workflow in Grasshopper. In this first video, I am building a test surface in Grasshopper. I use the Graph Mapper component to derive 3D points and Interpolated […]
