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]

Finally I had a chance to test and understand what the “vector force” stands for in Grasshopper. It creates a continuous flow of force inside of the boundary, and is very useful if you want to create a field that is under continuous presence of a directional force such as gravity. The definition is pretty much simple: [GHX: 0.9.0076] [3DM: Rhino 5]

Another tutorial we’ve analysed together with ARCH362 students last week was the one that mimics Zaha Hadid’s Kartal Masterplan. Although the project of Zaha Hadid was pretty much controversial among Turkey’s architectural critics (and most of the people also), we’re not dealing with how successful of “ugly” it is, but the most simple version of the technique that generated such forms. We have a term “çakma” in Turkish that means “conscious imitation, possibly full of errors”. But however, this “çakma Kartal Project” example has a pedagogical intention that a technique or concept could […]

This year’s Parametric Modeling class starts with some of the very basic use of Grasshopper concepts. This definition is a practical start-up of using force fields in architectural design process. However it does not compute any physical phenomena (such as circulation of people, wind or anything else), but shows a simple way to tell Grasshopper about walls that push the field, and points that pull the field. I’ll post more of these kind of basics, hopefully along with some student works. Here is the Grasshopper definition [GHX: 0.9.0076] and the dummy Rhino file [3DM: […]
