Stella: Polyhedron Navigator

"If you're unfamiliar with three-dimensional polyhedra, Great Stella gives you the chance to get acquainted in the on- and off-screen worlds"
Mike Bedford, PC Plus magazine, Issue 271, August 2008, p46
"I am finding Great Stella the greatest program ever devised for the use of polyhedron model makers..."

Stella News:
  • Polyhedral calendar and greeting cards designed by Robert Webb.
  • Polyhedra on display and article in The Age
    My paper polyhedra were on display for two weeks at Fed Square in Melbourne, Australia. An article appeared in The Age about it.
  • MoStella Android app released!
    The companion mobile app for Stella is now available! It's called MoStella and comes in 3 flavours:
    • MoStella Free - Platonic solids, Kepler-Poinsot and Archimedean solids.
    • MoStella Silver - Adds all the uniform polyhedra.
    • MoStella Gold - Adds stellations, compounds, Johnson solids, Stewart toroids and more.
    They can display duals, and morph between polyhedra and their duals in a couple of different ways. You still need the desktop Stella to create new polyhedra or print nets, but it's nice to have all these shapes at your finger tips wherever you go!
  • New Stella video!
    Produced a new introductory video for new Stella users.
  • Stella 5.3 released!
    See the version history for a list of changes. Existing users can upgrade from within the software using "Help→Check for Software Updates Now" (or in older versions: "Help→Check for Updates Now" or "Help→Check for Updates→Check Now").
  • Recent photos of paper models made using Stella
  • Now you can follow Stella on facebook
  • Stella on TV!
    The Today Show had a story about Great Stella back in 2003. You can watch it here.
  • Picture from Stella4D in New York Review of Books
    See it online here. It's the last image in the article, a picture of the tesseract.
  • Great Stella reviewed in PC Plus magazine
    Mike Bedford reviewed Great Stella for PC Plus, a UK magazine. Issue 271, August 2008, p46-47. See some quotes on the testimonials page.

Hi, and welcome to the Stella home page! Small Stella, Great Stella and Stella4D are computer programs which let you create and view polyhedra on the screen, then print out the nets required to build your own models out of paper. Small Stella has a fixed list of built-in models and can print out nets for over 300 polyhedra. Great Stella is more advanced, with many more built-in models, and tools for building literally trillions of new ones. Stella4D includes everything from Great Stella, but adds support for 4D polytopes too. 4D models can be projected into 3D, and you can see their 3D cross-sections and nets in real-time. Click here for photos of polyhedra I've made, all using nets printed from these programs, along with tips for building them.

The programs are fun and easy to use. Some of the jargon in the descriptions below may be a bit baffling at first, but you don't need to know anything about maths or geometry to be able to use these programs and create amazing polyhedra. They should suit everyone from the amateur enthusiast to the seasoned polyhedral expert! (There's a comprehensive glossary too, if you do get stuck).

Small Stella can display and print nets for over 300 polyhedra. You just pick a model, decide what size you want it, and Stella figures out what nets are required and prints them out. Then you cut them out, fold them up, and glue them together to build your own polyhedra! It is ideal for amateur model-makers or as an educational geometry tool for schools. You can always upgrade to Great Stella later.
