About the Images |
The Dodecahedron Day logo was created with POV-Ray 3.5. This versatile ray-tracing program may be downloaded for free at povray.org.
The polyhedron in the image is a regular dodecahedron. It floats above a corner constructed from the twelve pentominoes. If the pentominoes are contructed of cubes rather than squares, they may be arranged three-dimensionally.
This is more easily seen with the dodecahedron removed from the image. The vertex of the corner is omitted so that the arrangement requires exactly 60 cubic units.
The smaller images of the various dodecahedra were also created with POV-Ray 3.5.
The nets on the models pages were made with PostScript, then converted to PDF with the utility ps2pdf. PostScript programmers of the world, unite!
The navigation bar at the bottom of the main page is a tiling of a 5 x 12 rectangle using the twelve pentominoes. It is simply an HTML table. Click here to see another example using this method.
