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, 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 […]

It is a nice exercise to study various components of 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 […]

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 a “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 […]

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.[1] A vector field in the plane, for instance, can be visualized as a collection of arrows with […]

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, […]

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 […]

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: I hope I’ll be able to improve these sketches and publish their definitions […]

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, […]
