This was a couple of weeks ago, together with my six-year old son Mete, we decided to make a “ball” out of old memory cards. I was curious about a subdivision method, using only planar quadrilaterals to construct a sphere (named as Sixty Square Sphere. There are a couple of models on www. Of course look much better than mine :=). However my son was expecting a “ball” to play. Then, both of our expectations have been partially met, I think. You see the component configuration of squares that create triangular […]


This is the second year we are experimenting a beautiful exercise with basic design 1 students at İstanbul Bilgi University Faculty of Architecture. This is the construction of new year’s lanterns to be lit at campus garden. Here are a few photos of the two projects from 2012 and 2013, taken by Avşar Gürpınar. As a geometrical basis for this, we are conducting unrolling and stellation exercises combined with the basic idea of platonic solids and archimedian solids in Rhino. Benay has also introduced some interesting examples of such constructions. Here […]


Today’s Architectural Geometry course was about platonic solids and different attractor objects in introducing component-based design systems. Benay’s idea was both pedagogical and interesting to test in Grasshopper. I searched for the most fundamental type of attractor solid in creating a composition such as this; There is a subdivided sphere and an attractor sphere. Pull component works great here. You may use multiple attractor solids or different shapes such as platonic solids as attractors. It is a quite easy and funny definition to play with and to tell students about […]


Tetrahedron is a popular platonic solid for designers. We’ve explained how to draw them using equilateral triangles here before. Recently I’ve found (sorry, lost the web adress) a much quicker way of modeling a Tetrahedron using a cube. It’s very simple, just connecting the three opposite corners of the cube automatically makes them equal, resulting the four equal faces. Of course this time you’ll have to calculate the actual edge length, but if you use “box diagonal” command, you’ll also have opportunity to set the edge length of the tetrahedron. […]
