Create Polyhedra with Antiprism

Last year, I shared about Archimedean, a user-friendly software in exploring solids and polyhedra.  If you want to create polyhedra with a little bit of challenge, you may want to try Antiprism.  Antiprism is a set of command line programs for working with polyhedra. There are programs to create, transform, analyze, and visualize polyhedra.


An extensive collection of polyhedra is included, many accessible by name: Platonic, Archimedean, Catalan, Johnson, uniform, prisms, antiprisms, pyramids, cuppolas, trapezohedra, uniform compounds, isohedral deltahedra, geodesic spheres.

The Antiview viewer allows a model to be inspected using various options, including a display of a model’s symmetry. The models may be exported to POV-Ray for producing high quality images, or to VRML for viewing on-line.

The programs are easily combined in scripts, making it easy to generate a series of models, or frames for an animation.

The Windows package is freely downloadable and freely redistributable. A source package is provided for users of other systems.

An Intriguing Number Pattern Problem

Math and Multimedia Blog Carnival 20 via GeoGebra Applet Central

Welcome to the 20th edition of the Mathematics and Multimedia Blog Carnival. Here are the posts I have collected this month — some from the Blog Carnival site and some from my RSS feed.

Before we begin a carnival, let’s have some trivia about the number 20.

  • The number of sectors in a dartboard.
  • The atomic number of calcium.
  • It is the smallest primitive abundant number
  • The number of faces of an icosahedron
  • Can be written as the sum of the three Fibonacci numbers: 13 + 5 + 2

Week in Review – February 2012 Week 3

Good morning from Baguio City (6 hours from Manila), the summer capital of the Philippines. I am here for a one-day lecture-workshop on “Mathematics as a Way of Thinking” at the AEIRS National Conference.

After sleeping for 7 hours,  I feel rejuvenated, so I am going to list the most recent posts for this week.

That’s all for this week. Have a blessed Sunday!
