Today, we’ve discussed ways of subdividing entities to create parametric definitions. Curves can be divided into segments, creating snake-like object definitions. This exercise is important regarding the management of data. Vectors and planes are used as reference entities here. Nowadays, it became clear to me that, reference planes are very important because they both include reference points and related vectors as well. The definition studied in this post includes a curve subdivision and a combination of vector / plane management to…

This was an interesting topic in design computing class. Geometric constructions based on strict relationships are becoming exciting in parametric modeling environments. I think muqarnas includes such a relationship. There is a primary method of modeling this shape, introduced by Mete Tüneri. His solution to a simple parametric muqarnas object includes a surface with six reference points, with two boolean differences (one cylinder and one box) creating the component. In Grasshopper, I tried to simulate his process by adding real-time…

SPEC disappeared from our garden suspiciously. Hopefully, we’ve already finalized its parametric survey. Can create the original model by measuring exact corner coordinates. Then, it manipulated shape by creating diverse vectors for each shape. Emre has also tried a similar approach. Can be definition was too long, and did not use data trees, therefore it is slow. But it’s very effective at offering a solution for animation. I re-captured his frames for animation: Another innovative solution came from Yağız along…

Here is a funny sketching system for the “SPEC” homework. Four (or more) points are created using 2d sliders (MD slider) and decomposed these points into x,y and z numbers. Then, they are re-populated in 3d points by changing their plane. X coordinates are connected into Y, and Y coordinates are connected to Z’s. Tricky part comes then, the X number is defined by a serie of numbers started from 0 to 30 by 1. After that, polylines are constructed using…

Today, we’ve studied ways of representing multiple data structures in Grasshopper at ARCH 362. As of our last week’s experience, sometimes (most of the time actually) we’ll need to work with vast amount of data. We’ll have to control them in order to open door for further explorations. Today’s exercise was a good example of this “sustainable” process of data management. All functionality of Grasshopper is based on data matching. From short-list, long-list matching, to the structures of data trees….

This is the basic definition of one point attractor on a grid of points. Here, the fundamentals of data tree matching can be studied. A hexagonal grid is exploded into points and new polygons are created there. Instead of a standard point distance relation to polygon size, this time the distance factor affects the rotational angle of these polygons. Although the structure of data trees is getting complicated, this has no difficulty in such definition, because the operational complexity is still very…

Maybe a huge kitsch for contemporary architecture, I know, but a good example of a fundamental problem of constructing geometric relationships. In ARCH362 today, we’ve examined the geometric modeling process that opens us to parametric relationships just by converting it into a diagram of design history. You may follow the construction of such a diagram step by step and see the possible parameters emerge from it. The only rule of this construction is the connection from the left side of…

Here are some of the results of first assignment, “Reptile Skin”. Generally, we couldn’t manage to develop innovative solutions to the problem. But this became a good starting point for understanding the method of “skins of components” in contemporary digital design. Before going into any control over the flow of data, it’s hard to maintain associative geometries. We usually feel stuck within the capabilities of the single commands or procedures. That’s why, digital design deals with “processes” much more intensively…

That was about six months ago, our study for a design competition required a spatial allocation algorithm. An office building with a rectangular plot and a strict functional requirement forced me to the good old Voronoi diagrams, subdividing a surface. However, there were other design parameters such as the sunlight and orientations of each functional cell. Combining a couple of graph components helped me create diverse solutions later used in the functional-formal interpretation phase. Unfortunately, later on, the competition was…

This is the old-method Parametric Truss definition. Interestingly this quickly became a solid solution, used and taught for years. I couldn’t find a better answer yet. As Grasshopper updates, some of the components in this definition change but the overall structure remains. Subdivision of a free-form surface and addition of geometric components has, of course, a wide range of alternatives. Maybe we should combine this with different problems and solutions we’ve talked about earlier on this website. The same solution…
