Below are some of the student works from 4th week of this semester’s Basic Design studio. The gestalt notion “figure-ground phenomenon” refers to the characteristic organization of perception into a figure that ‘stands out’ against an undifferentiated background. What is figural at any one moment depends on patterns of sensory stimulation and on the momentary interests of the perceiver. Figure-ground relationship is an important element of the way we organise reality in our awareness, including works of art. Poets may rely on our habitual figure-ground organisations in extra-linguistic reality to […]

This was a month ago, I was searching for a way to work with random points and growing populations. Then this idea appeared accidentally. I wasn’t trying to mimic the behavior of biologic cells (in fact I’m in a serious doubt about biomimicry in general). The trick is to use timer + data recorder + a knob for the arbitrary user input. It starts to breed when you start the timer, but in order to change the evolution speed, just roll the knob!  Of course the knob is as precise […]

I learnt this method from the open math resources website. I couldn’t help myself repeat it in Rhinoceros. It was quite fun to solve circle tangency problems in 2D, this is one of them: drawing the circle that passes three given points, not using ready-made commands but only geometric tools of circle (compass) and ruler (line). Here is the sequence of it: First of all, we need to know that the circle we are looking for is centered at somewhere on the perpendicular paths between the points. This means, we […]

This was the initial example of image processing at our Parametric Modeling class. I saw this design at Maxthreads Architectural Design’s website (especially here). Hand-drawn and digital diagrams can also be digitized and used in order to describe certain parameters for design formation. Such algorithms would similarly use Image Sampler Component of Grasshopper. In the algorithm below, image data is used to capture black pixels as attractors of a Voronoi subdivision. A regular point grid is dispatched according to Brightness values so that the points lie on the lines of the drawing […]

After the first three weeks of research, students at Parametric Modeling course is ready to fire a blog, putting their survey results, ideas and selected example projects around the World. This is the web address so that we’ll be able to check their progress here:  

Here is a simple explanation about the famous Euclidean Constructions: Why didn’t Euclid just measure things with a ruler and calculate lengths? For example, one of the basic constructions is bisecting a line (dividing it into two equal parts). Why not just measure it with a ruler and divide by two? One theory is the the Greeks could not easily do arithmetic. They had only whole numbers, no zero, and no negative numbers. This meant they could not for example divide 5 by 2 and get 2.5, because 2.5 is […]

Grasshopper still surprises me. This definition draws a spiral by using random component. It is obvious that the seed value of the random component has a relationship with an archimedian or a similar spiral. My intention was to create a definition to put a number of random points inside a circular area, not a rectangular one. While I grow the radius of a circle and get a t parameter evaluation from a random component using the same seed value with the radius, the resulting points started to create this spiral. […]

One at the Center is a multiple-axes vertex deformation based on a quadrangular hyperframe, designed by David Oleson at the studio of William Huff in 1964. Below, you see the original drawing and my Grasshopper animation based on a single point attractor, creating the “one” whereever it is. It was a pleasure to read and repeat this deformation, which is a nice exercise of data tree operations and also one of the first examples I see about point attractor algorithms in design education. Here is the Grasshopper file; if you are interested; [GHX: […]

This simple component controls Rhino viewport background without a need to enter it’s options panel. It is used to change viewport background color and grid visibility quickly within Grasshopper. Here is the definition file: [GHX: 0.9.0056]. In order to be able return to default settings, I put a “default” toggle. Just click on it to “false” state, then the Rhino background color can be changed by the B input. This component also handles the grid. However I couldn’t find a working method to hide and show the Rhino grid within […]

Instead of searching for an iterated and rule-based variety, this method captures instances of a spatial deformation by transforming the hyperframe. This liberates us from classical understanding of pattern deformations that are enframed within regular polygons, mostly rectangles or hexagons. Grasshopper has a built-in component to study such variety. Spatial Deform component gets vectors as inputs and transforms any given geometric object according to it. This website has also another nice use of this component. Here is the Grasshopper definition including the Islamic Pattern cluster from semi-regular tessellations, and spatial […]
