A Non-Convex “Bowtie” Polyhedron

Image

To form this polyhedron, I took a rhombic dodecahedron, and augmented each of its twelve sides with additional rhombic dodecahedra, forming a cluster of thirteen of these space-filling polyhedra. I then stellated this cluster thirty-four times, and this was the unexpected result.

The software I used to do this may be found (and tried for free) at http://www.software3d.com/stella.php.

Twenty Hexagons with Heptagrammic Designs

Twenty Hexagons with Heptagrammic Designs

The design on the hexagons appeared in the last post here, and was created using Geometer’s Sketchpad and MS-Paint. After that, I used another program, Stella 4d, to place these images on the hexagons of a truncated icosahedron, render the pentagons invisible, and create this rotating .gif file.

The great dodecahedron here is red, and the yellow polyhedron is the sixth stellation of the icosahedron.

This, like “Dark Stars” before it, was based on previous posts. I stellated the post two posts ago, several more times. Software credit: http://www.software3d.com/stella.php

This is a polyhedron with 140 faces, all triangles. There are:

  • 20 equilateral triangles
  • 60 visible isosceles triangles
