The C-320 Fullerene Polyhedron

Posted on 7 October 2017 by

The duals of the geodesic domes are polyhedra with hexagonal and pentagonal faces. This particular one has 320 vertices, with those vertices representing carbon atoms. Here is C-320 as a polyhedron. The next image shows this molecule as a ball-and-stick … Continue reading →

A Faceting of the Rhombcuboctahedron

Posted on 30 September 2017 by

This particular faceting of the rhombcuboctahedron can also be viewed as a cluster of stella octangulae. I made it using Stella 4d, polyhedron-manipulating software you can try, for yourself, at http://www.software3d.com/Stella.php.

The Truncated Stella Octangula

Posted on 25 September 2017 by

This can also be called the compound of two truncated tetrahedra. This image was created using Stella 4d, which you can try at this website.

Creating a New Polyhedron from the Snub Dodecahedron

Posted on 13 September 2017 by

Shown below are the snub dodecahedron and its dual, the pentagonal hexecontahedron. Seeking a way to make a “new” polyhedron (one never seen before), I augmented each face of the orange dual, above, with prisms. These prisms have a height … Continue reading →

The Cubic Rhombicosidodecahedroid

Posted on 10 September 2017 by

I call the polyhedron above the cubic rhombicosidodecahedroid because it combines a cube’s six squares (shown in green) with the overall appearance of a rhombicosidodecahedron. For comparison, the latter two polyhedra are shown below. I made these rotating images using … Continue reading →

An Expanded Version of the Snub Cube

Posted on 1 September 2017 by

To make this polyhedron, I started with a snub cube. Next, I augmented all triangular faces of it with prisms, then took the convex hull of the result. Finally, I used Stella 4d‘s “try to make faces regular” function on the … Continue reading →
