#grid

I am still trying to find the simplest solution to some geometric definitions. This is why I called this Grasshopper definition “Basic Grid Deformation”. Here you see the Curve Proximity (CrvProx) component in use. This component calculated the shortest distance between two curves. I think the underpinnings of this component are very interesting. I hope I can code it in Python one day. In order to see the result more clearly, the Previews of the Interpolate Curve (IntCrv) and Square…

This python code proves how much effort it takes to create a simple hexagonal tessellation. There are, of course, much easier and faster methods than this. But here you see a code that introduces students to Rhino Python. Using this code, a new Rhino command can be generated, and for the first time in Rhino, we can have a command that creates a hexagonal grid. I followed this tutorial to turn this Python script into a Rhino command. This is…

This is one of the three final projects of the Infections workshop at YTU. The conceptual framework is developed by Begüm Aktaş (YTU) and Merve Özhan (BAU). According to them; the existing host body is a 16×11 unit glass brick wall, which is constructed to separate the corridor of the faculty and to create semi-private spaces for various activities. In this project, the host body is considered the dead tissue of an organism. Sound is considered an injection that changes…

It all started with my new passion for origami tessellations, not much of origami, but the tessellation part. I was too lazy to fold it physically, nor model them using an engine such as Kangaroo. That would also be very unnecessary (and yes, very boring) to simulate a folding effort on the computer unless we lose our connection with the real world. Instead, I tried to look at a much more abstract, silly, and basic part of it; the creasing…

After playing with vector fields in 2d (here) it was quite easy to create a 3d surface deformation. Here is my first experiment on a regular triangular grid’s three-dimensional behavior within a vector space, that includes a point charge of varying z coordinates. That makes field lines escape to a bounding box, instead of a bounding rectangle. Again, you may play with force decay, the number of samples, and the “grid blast” parameter, which is just a t-value evaluation of…

Back to the basics. I finally had time to test the vector fields components in Grasshopper. It was a couple of updates ago, a new tool group emerged in the vector tab, introducing different types of vector fields to users. Then, these fields could be merged to form more complex effects. However, I created a very simple example of how we can use those components to distort a system (such as a regular tessellation).  Using attractor forces (usually in geometric…

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…

Wow! Is this possible in Grasshopper? In order to start creating recursive algorithms in Grasshopper, I finally managed to run Hoopsnake, a special component developed by Yiannis Chatzikonstantinou. This will help me develop parametric models that include loops. The fundamental experiment here shows a surface subdivision based on iterations. We should define a starting object or data, an operation to be repeated, and a limit that will tell Hoopsnake to stop looping. In this condition, this is the area of…

Here, I used a curve to accomplish grid tearing. It’s straightforward, and from an educational perspective, this exercise includes several potentials on vector arithmetics and graph manipulation techniques. As a design domain, this definition stresses the use of associative entities in a parametric model. Any primitive or complex entity may evoke different parameters in others. The beauty in the simplicity of these algorithms still amaze me.
