The A-Chord folding structure was developed and constructed for the World Wood Day 2015 event in İstanbul. The structure had fifty wooden struts of 4 cm X 4cm with changing heights from 200 cm to 230 cm. Two struts joined with a hinge enabled the folding motion of the structure. Thus, the nearby unit is folding in the opposite direction. The Grasshopper model generated all construction details and drawings automatically. As a result, these data enabled the revisions needed for structural experiments. In…

Based on this post, the problem of modeling tree-like fractal shapes is still a good question for the early years of computational design education. Last time, I used Rhino’s macro to study these fractal trees in an “impossibly” limited interface. But this time I used a VB.NET script. Here is the code inside of the VB.net component: Here are the inputs. x is the number of iterations. The Crv input is a line needed for the first iteration. t represents how…

Some facade studies as early sketches of an architectural project; all of them are utilizing a similar Grasshopper approach. My favorite “Graph Mapper” generates the overall gridal deformation, then some of them are drawing geometry for membranes, while others are generated to be realized from sheet metal. Hopefully, one or two of these could be further studied: “Below, I am sharing my favorite among these codes. I had to pull off some geometric acrobatics to affect all four facades of…

Further studying iteration in Grasshopper, this time, inspired by George Stiny’s “Chinese Ice-Ray Lattice” subdivisions with Aneome, instead of the Hoopsnake add-on I tried in the previous work. As you know, loops add various ways of usage to Grasshopper. In future versions, loops may cease to be just an add-on and become native components of Grasshopper. Until then, loop plugins like Anemone take on this task. In the example here, we create an application by throwing random lines to divide…

About to finish the well-defined section of this year’s Parametric Modeling course, here are the mid-term questions I’ve asked; First question checks if the curve < > point conversions are well understood in Grasshopper. Evaluating a parametric curve and generating the closest point from another curve. This also requires a basic understanding of the use of the Grasshopper interface. The second question was testing a basic and classical use of attractors on grids of objects. Students generated their own grids…

This is a great book, explaining very familiar concepts of dataflow diagrams for designers firsthand. Leveling is an interesting chapter there, I’m not sure if it completely fits with the use of “Clusters” in Grasshopper but it is obvious that the complex systems should be well organized not only to be perceptually “better” ones but also to develop a way to use parts of definitions again and again in different situations. …How do you actually DO the leveling of DFDs? The…

Site models could be calculated for laser cutting easily using Grasshopper’s native components. This definition was a practical one we created in the Parametric Modeling course to see that Grasshopper could also be utilized to prepare fabrication documents not generating design outcomes. However, this definition is a draft one and could be improved more by putting labels inside of each cut piece, trimming the edges properly and so on. It is good news for students at least that they have a…

This is a useful tip both to solve some of the problems with custom surface subdivisions, and to explain the uses of parametric surface evaluations (the U, V, W thing) and the practical use of data lists. Step 1: Put your points inside 0,0,0 and 1,1,0 so that the resulting coordinates can easily be converted to U and Vs. In the example, we are putting some random points between 0,0 and 1,1 using the Populate2d component. Step 2: Then make whatever you…

Image Sampler of Grasshopper saves life if used responsibly. While explaining the component to this year’s ARCH362 students, I used this simple example that generates numbers from a beautiful picture of “metal foam” and uses it to generate lots of circles: Metal foams are lightweight but strong materials, that are typically produced by injecting gas into the liquid metal. Of course, it becomes easier to teach something when you manage to attract the attention of students.

Finally, I had a chance to test and understand the force fields tab in Grasshopper. It creates a continuous vector field inside of a given boundary. Therefore, it is very useful if you want to create an effect of the continuous presence of a force, such as gravity. The Wikipedia definition of a vector field is very basic and understandable: In vector calculus and physics, a vector field is an assignment of a vector to each point in a subset of space. For instance, a vector field in the…
