Model: K2 Diagram: moduł Toma Hulla Twórca: Robert Lang Komentarz: 20 przecinających się trójkątnych ramek, dokładniej to 5 przecinających się czworościanów, który zbydowany jest z 4 przecinających się trójkątnych ramek. Jeden z najtrudniejszych modeli modułowych. Diagram: Tom Hull unit
2012 in review The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog. Here’s an excerpt:
The Dixiesphere is composed of twenty spherical-hexagonal 7-cup modular units, which you will construct first. Each hexagonal modular unit consists of seven cups hot-glued together such that one central cup is surrounded tangentially by six more cups. (The spaces between cups will look like equilateral triangles with concave edges, and the circular bases and rims of the cups will look like hexagonal close-packings of circles, but they will posess a slight overall curvature, as the circles define the surfaces of spheres.) It is important that the central cup contacts each of its surrounding six cups at their bases.
Instuctions for making this model Below is the Sonobe unit, designed by Mitsonobu Sonobe, which I learned from Kazuyo Inoue. Above is the capped icosahedron which she made for me from this unit; you need to make about 30 units for this, but you only need six if you want to make a cube. Since this must be very well known, I'm only putting a very brief picture of how to make it. The second line of instructions gives a little more detail for the last step. Just in case you want more details than above, you can find some more diagams here and here .
Modular Origami VRML Models Modular origami involves folding several identical or similar pieces (called units ), which are then joined, usually without glue. Although I prefer single-sheet origami, some modular models are extremely attractive and elegant, not the least in the mathematical sense.
