Poly includes all of the following polyhedra:

Platonic Solids

  • Tetrahedron
  • Cube
  • Octahedron
  • Dodecahedron
  • Icosahedron

Each platonic polyhedron is constructed using (multiple copies of) a single regular polygon; the same number of polygonal faces is used around each vertex. A polygon is regular if all of its edges have the same length and all of its interior angles are equal. Both the equilateral triangle and square are regular polygons.

Archimedean Solids

  • Truncated Tetrahedron
  • Cuboctahedron
  • Truncated Cube
  • Truncated Octahedron
  • Rhombicuboctahedron
  • Great Rhombicuboctahedron
  • Snub Cube
  • Icosidodecahedron
  • Truncated Dodecahedron
  • Truncated Icosahedron
  • Rhombicosidodecahedron
  • Great Rhombicosidodecahedron
  • Snub Dodecahedron

The Archimedean solids were defined historically by Archimedes, although we have lost his writings. All of the Archimedean solids are uniform polyhedra with regular faces. A polyhedron with regular polygonal faces is uniform if there are symmetry operations that take one vertex through all of the other vertices and no other points in space. For example, the cube has rotation by 90° around an axis and reflection through a plane perpendicular to that axis as its symmetry operations.

A common heuristic for the Archimedean solids is that the arrangement of faces surrounding each vertex must be the same for all vertices. Although all of the Archimedean solids have this property, so does the elongated square gyrobicupola (Johnson solid #37), which is not an Archimedean solid.

Prisms and Anti-Prisms

  • Triangular Prism
  • Pentagonal Prism
  • Hexagonal Prism
  • Octagonal Prism
  • Decagonal Prism
  • Square Antiprism
  • Pentagonal Antiprism
  • Hexagonal Antiprism
  • Octagonal Antiprism
  • Decagonal Antiprism

After the Platonic and Archimedean solids, the only remaining convex uniform polyhedra with regular faces are prisms and anti-prisms. This was shown by Johannes Kepler, who also gave the names commonly used for the Archimedean solids.

After taking into account the preceeding three categories, there are only a finite number of convex polyhedra with regular faces left. The enumeration of these polyhedra was performed by Norman W. Johnson.

Catalan Solids

  • Triakis Tetrahedron

The Catalan solids are duals of Archimedean solids. A dual of a polyhedron is constructed by replacing each face with a vertex, and each vertex with a face. For example, the dual of the icosahedron is the dodecahedron; the dual of the dodecahedron is the icosahedron.

The first geodesic dome was designed by Walter Bauersfeld and was built in 1922. Several decades later, Buckminster Fuller popularized and extended the ideas behind geodesic constructions.

To construct a geodesic sphere, you first choose a convex polyhedron which will serve as a framework for the construction. The next step is to ensure all of the polyhedron’s faces are triangular: each non-triangular face is triangulated by connecting its vertices to a new vertex placed at the center of the face. You will then have a 1-frequency geodesic sphere if all of the vertices are made to be equidistant from the center of the polyhedron by moving them directly away from or towards the center.

Higher frequency geodesic spheres may be constructed by replacing each face with a regular triangular mesh and then ensuring all of the new vertices are equidistant from the center. 2-frequency geodesics bisect each edge of their associated 1-frequency geodesics by using 4 triangles for each mesh; 3-frequency geodesics trisect each edge and add one vertex to the center of each face of their associated 1-frequency geodesic by using 9 triangles for each mesh.
