A Black-on-Black Polyhedron: The Final Stellation of the Icosahedron

Icosa

I made this using Stella 4d: Polyhedron Navigator, which you may try for free right here.

Spectral Circles on a Cuboctahedron

Cubocta

I used three programs to make this: Geometer’s Sketchpad, MS-Paint, and Stella 4d. The third of these may be tried for free at http://www.software3d.com/Stella.php.

Spectral Circles on a Truncated Icosahedron

Trunc Icosa

I used MS-Paint and Geometer’s Sketchpad to make the designs on the faces, and then used Stella 4d (here) to put the whole thing together.

A Dozen Pulsating Dodecahedra

Posted on 6 April 2017 by RobertLovesPi

12 dodecahedra

To make this using Stella 4d (available here) I started with an icosahedron, placed a dodecahedron on each of its vertices, then rendered the central icosahedron invisible. The slight pulsating effect is caused by the program fitting the polyhedra tightly into each frame of the animation.
