Winter is coming soon!
This is a continuation of the process shown in the last post here, but with a different coloring-scheme.
I made this using Stella 4d, which you can try for free at this website.
This is based on the well-known tessellation of squares and regular octagons, but with each line segment replaced by two semicircles.
The blue polygons are regular pentadecagons, and the yellow polygons are irregular dodecagons. There are also equilateral hexagons (orange), red squares, and black concave pentagons.
These polyhedra are the rhombic dodecahedron (above), and the rhombic triacontahedron (below).
I made both of these using Stella 4d, which you can try for free at http://www.software3d.com/Stella.php. The tessellation on the faces of these polyhedra first appeared right here on this blog, in the post just before this one.
