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 […]

Previous studies on the timer component were based on understanding it’s use. This time, I tried to implement it in a geometric design task. Moreover, manipulating timer component to change the regular animation of parameters. Time does not have to be equally divided sequences. Rather, new possibilities may be emerged with different time flows. A simple triangulation system is developed with a potential manipulation, based on a timer. This definition is exciting and new for me because I’m not designing geometry here, rather I’m trying to manipulate the flow of […]

This is the final project of group 2 at İstanbul Bilgi University Faculty of Architecture Basic Design II Spring 2012 undergraduate studio*. 1:1 material system is constructed by two layers of tesselfations, triangular and hexagonal. They studied much for the connection detail and elaborated the structure to maintain stasis within a dynamic pose. They have used a Grasshopper definition (described here) to label and measure all of 800 rods into Excel. Very hard work, intellectually and physically has finished. Congratulations! Although the underlying geometric system is purely deterministic, small changes […]

Digging out with Grasshopper, Rhinoscript and Paneling Tools, everything seems to be more and more automated and fast. However my colleagues Mete, Benay and Elif reminded me that, we can always do much with those high-end architectural geometry tools; but we still have to understand and follow the roots, probably best described by the “manual ways”. Sometimes using these methods would be much more intuitive as they are SLOW enough for designers to think about what is going on there… Here is a good example we experimented with our undergraduate […]

Here is a funny sketching system for the “SPEC” homework. [GHX: 0.8.0066] 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 the new point list. Data recorder is initialized to […]

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 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 in this website. Here are the geometric model and parametric definition files. [3DM: truss] [GHX: 0.8.0066] The same solution can […]

[2011_12_25_divide] here is the fundamental of surface subdivision in Grasshopper. In order to design a parametric truss exercise, this is generally accepted starting point. Get a surface from the file, subdivide it into U and V directions to create point lists and then manipulate these points to create something interesting. Having a list of points would also present good potentials regarding attraction with other entities, such as point or curve attractors. As you probably notice, this is the new version of Grasshopper, which also includes NURBS objects. As a parametric […]
