| 説明 | We want to base our Future Professionals' Day this year around hexagonal flat units. The question of what one can make with such polygons as a building block naturally arises, and I suppose the most common answers would be truncated tetrahedra and truncated octahedra. As a bonus, both of these polyhedra exhibit tetrahedral symmetry, so they could be used to create large tetrahedral symmetry "toroids", but meh.Instead, I looked for honeycomb tessellations that happened to include the polyhedra above. I was not disappointed! One (relatively) simple honeycomb stood out from the crowd: the cantitruncated cubic honeycomb.Making something like this would have been fairly simple: take eight truncated octahedra and separate them with 12 cubes so that the end result simulates a "larger cube." There remained the problem of what to do about the big, great-rhombicuboctahedron-shaped central void (surely not "nothing"; how boring is that?) until I realized that the void itself was part of a smaller honeycomb that I had made before. This smaller honeycomb would become, I decided, the core of the structure.Both the great rhombicuboctahedron I had already made and the proposed one could be realized by connecting eight triangular cupolas together using 12 cubes. The chief difference between this model and that one is "emphasis"; the previous model emphasized the triangular cupolas, but this model uses colors to emphasize the square cupolas instead.For those of you who wish to create the object pictured here, there is a simple pattern to follow: each triangle--and there are 24 of them--shares an edge with two squares on one side, two squares on another side, and nothing on the third. (You will need to put two joining tabs together back-to-back in order to get the "Y"-shaped tabs necessary to connect two squares and one triangle to the same edge.) Repeat this pattern over and over and you will have your core. |
