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 produce a solid model. In this application, after we obtained…

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…

Let’s have some fun with the parametric stuff! You may remember that we created many vases and glass alternatives that we could bake with a single Revolution (RevSrf) component in previous exercises. Since we were referencing the profile curve drawn in Rhino, it was also possible to create a one-component glass algorithm with some Rhino knowledge. Now, we will try to develop a parametric mug. In the application you see here, we carried out the drawing of the profile curve…

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….

I have created a straightforward Grasshopper code that generates a Voronoi diagram on a surface. Then, it adds thickness to form a structure called a “Voronoi Cage.” In the initial step, I project a surface onto the ground plane (Z=0). The projected frame serves as the boundary for two operations: generating random points using the Populate 2D (Pop2D) function and calculating the Voronoi diagram based on these points. The resulting Voronoi cells are then slightly offset inwards. Moving on to…

This is an update on my 2012 exercise on rhombille tiling. This reminded me of the old-school subdivisions of surfaces again after 11 years. It was while reading about rhombic dodecahedron (the stackable solid), that I came across this cute tiling. It’s quite simple, just a hexagonal grid with a special reconstruction. I decided to recreate it by using well-known native Grasshopper components. I animated the result with a variation of the Breaststroke surface function (described here). Then I reconstructed…

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…

Data structures and data matching principles are important to be able to design with Grasshopper. In this tutorial, I show data matching procedures with arithmetic operations. Then I repeat them in the production of geometric objects. I think it should be easier to use this programming language once the students understand the basic principles. Therefore it would be easier to design with it. Sometimes the design process of these diagrams proceeds from left to right (by induction) but sometimes it…

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…

Here is another basic exercise in Grasshopper. This exercise “Point Waves” creates wave-like deformations on the grids of points. The major function of the definition is to calculate the distances from every point of a grid to an attractor point, with the help of Distance (Dist). Then it sorts them from the smallest to the largest (= closest to farthest) with the Sort List (Sort) component. This component takes and matches two lists of the same size, called key (K)…
