This is done because I needed to represent relationships between different factors and layers of a design process. Although this method of “Chord Diagrams” is a very common technique in information design, it became very hard to find an effective tool for generating those diagrams quickly. There seem to be a solution called “Circos” but however even installing it to the computer became very boring for me. So I decided to make a Grasshopper definition that generates simple circular relationship diagrams. The resulting Grasshopper definition ([GHX: 0.9.0076]) seem to be a […]
This project started as a study on a geometric method, called as quadror, but resulted as an amazing self-standing structure with a capability to fold flat. Initially after Ayza made lots of sketches and models, the project team continued the research and finally they managed to build one prototype only in two days. Here are some photos of this project but there are much more variations and models at their own blog linked below: Below are some photos of their research: This is supposed to be the final prototype. *Students: […]
This final project of the Computation-based Basic Design II at IBU, focuses on the bending performance of wooden plates. Their initial development of a module ended up with a macroform that spans a surface in two directions, enabling various human postures such as sitting, leaning and lying down. A very promising work that could further be developed. Below are some photos: Final prototype The idea and the process. *Students: Azra Tulu Cumur, Batuhan Güllü, Büşra Kılışlı, Cem Mert Şimşek, Fatma Oran, Onurcan Oktay Here is the student blog of this […]
Another well organized group of students produced this self standing structure in only a couple of days. This group joined the same 8mm wooden plates into a set of components of 8-sided polyhedra. Then, they joined these components in a fashion that the macroform emerged from the angles of their geometry. Below are some of the pictures of their production phases: The final prototype Some phases of the production Model of the component and the macroform. *Students: Başak Ayris Karayiğit, Dila Kırmızıtoprak, Dilruba Ağaçcıoğlu, Ecem Karabıyık, Elifsu Oturan, Maide […]
A very hard working group of this year’s Computation-based Basic Design Studio produced this amazing structure. They joined 8mm cnc-cut wooden plates using puzzle-like cuts and tightened with strings. A good example of group coordination produced this result in two days. Below are some photos of the prototype and the project phases: Final prototype. The joint details and the first experiments. *Students: Aslı Naz Çolakoğlu, Aybike Yılmaz, Bilge Kardelen Bekiroğlu, Büşra Hamzaoğlu, Ceren Bilen, Simay Uluca, Zülal Atakul Here is the blog of this project.
In this final project, wooden sticks are arranged to produce ruled surfaces for various uses such as sitting, leaning etc. Here are some photos of the final prototype and it’s production phases. Final prototype Digital model First sketches. *Students: Dilara Çerçi, Elham Kaya, Gizem Kama, Gül Zorlu, Gülşah Kılıç, Orhan Ünver, Yiğit Altındağ, Sena Ortaç Here is the students’ blog on this project.
After several readings I’ve understood the way of working the new and very interesting feature of Kangaroo 2: “Grab”. Now, we can actually grab the Grasshopper objects from Rhino viewport! Also, while on one hand the new Kangaroo has a very special way of working (not common to us, native Grasshopper users) and on the other hand, it is very very easy to use and understand now. I loved that. Here is the classical truss exercise I’ve made with my students at Parametric Modeling class; This is the […]
It is a nice exercise to study various components about point to curve transformations and vice versa. Tower Crane was our second week exercise at İstanbul Bilgi University Faculty of Architecture Parametric Modeling class, asking students to design and draw a parametric object that has joints and parts that are moving alongside straight lines. Below is the most “safe-side” solution for me, although there are also very complicated solutions such as Mertcan’s. [GHX: 0.9.0076] here is the Grasshopper definition.
This is a classical method of generating tree-like forms utilizing a simple command “Arc SED”. The idea is simple, as the command draws arcs using an input direction vector, so this could easily be implemented creating “smooth” composition of curves just by iteration. Actually, this has been a previous study, discussed before here, using Hoopsnake. Now, this time I’m implementing the same algorithm using Anemone and a couple of other changes. Here is the Grasshopper definition (Anemone Components should be installed first): [GHX: 0.9.0076].
Utilizing “Force Field” components of Grasshopper to show my students how it is easy to develop flexible surfaces in design. The classical parametric canopy design is introduced in this video: According to Wikipedia; In vector calculus, a vector field is an assignment of a vector to each point in a subset of space. A vector field in the plane, for instance, can be visualized as a collection of arrows with a given magnitude and direction each attached to a point in the plane. Vector fields are often used to model, […]
“A-Chord” design system is developed and constructed for the World Wood Day 2015 events in İstanbul. The structure is made of fifty wooden struts of 4 cm X 4cm with changing heights from 200 cm to 230 cm. Single unit of the structure is formed by two struts joined with a hinge to enable folding, while the nearby unit is folding to the opposite direction. The construction details, measurements of the struts, positions of the hinges, angles of the tensile chord axis are generated automatically by the parametric model. These automatic construction data enabled the revisions […]
Based on this post, the problem of modeling tree-like fractal shapes is still a good question for early years of computational design education. Last time, I used Rhino’s macro to study these kind of fractals in an “impossibly” limited interface, but this time both vb.net and Anemone are introduced to students. First, using a Vb.net component that creates “the binary tree”: Here is the Grasshopper definition if you would like to see the simple vb.net loop in there: [GHX: 0.9.0076] (Don’t left click on the link, right click and “save the file” to your computer). Then, […]
Some facade studies as early sketches of an architectural project; all of them are utilizing the similar Grasshopper approach. My favourite “Graph Mapper” generates the overall gridal deformation, then some of them are drawing geometry for membrane, while others are generated to be realized from sheet metal. Hopefully one or two of these could be further studied: I hope I’ll be able to improve these sketches and publish their definitions soon.
Further studying iteration in Grasshopper, this time, inspired by Stiny’s “Ice-Ray”ish subdivisions with Aneome, instead of Hoopsnake in the previous work. Here is the Grasshopper definition (Requires Anemone components to be installed first): [GHX: 0.9.0076] Of course this is just an inspiration not the real scientific study Stiny has conducted (although I receive lots of emails about the previous Hoopsnake implementation; guys I’m not sure if this kind of algorithms are suitable for academic studies). Anyway this definition chooses random splitting directions of a surface for every iteration.
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 closest point from another curve. This also requires a basic understanding on the use of Grasshopper interface. Second question was testing a basic and classical use of attractors on grids of objects. Students generated their own grids and put pyramids on each cell, as the height of these pyramids would […]
This is a great site, explaining very familiar concepts of dataflow diagrams for designers from the first hand. 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 diffierent situations. …How do you actually DO the leveling of DFDs? The discussion thus far has been misleading in […]
Site models could be calculated for laser cut easily using Grasshopper’s native components. This definition was a practical one we’ve created in 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 pieces, trimming the edges properly and so on. It is good news for students at least that they have a chance to generate topography models from the AutoCAD maps mostly used […]
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 Populate2d component. Step 2: Then make whatever you want with these points. For example we can create voronoi subdivision or delaunay […]
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 stong materials, that are typically produced by injecting gas into the liquid metal. Of course it becomes easier to teach something when you manage attract the attention of students. Here is the Grasshopper definition that shows the basic use of image sampler component: [GHX: 0.9.0076]
