Origami Polyhedra: The Stellated Dodecahedron Part 2

A little while ago I posted some pictures of Stellated Dodecahedra I made in origami. Here the crease patterns for them. You see, in addition to folding origami, I’ve taken an interest in diagramming, and someday I hope to publish a book of my models. But I find diagramming so laborious that I only do one model a year! (Although they do tend to be pretty complex models.) I’ve also been developing crease patterns, which is particularly useful for polyhedra and other complex subjects where there is a lot of prefolding.

I do my diagramming and CP’s in Flash, and I’m not aware of other people doing this. One reason is I use Flash a lot in my day job, so I know it and can work in it quickly. Another is that I can use to make animated diagrams and CP’s. You can see some of them on my main origami page. This is an experimental format which I am refining over time. It had its origin in the Foldinator Project. Foldinator was originally envisioned as a full-on authoring tool for modeling origami and creating printable diagrams. However, to get there is a rather major development effort. So instead I wound up with this little hacker-level tool that I use. I still hope to finish and release Foldinator someday, but I’d need to treat it like a professional software development project and devote something like 6 months to a year of full-time work to it. Ah well, maybe if I’m lucky I can do like Robert Lang and retire young to do origami full-time.

Meanwhile, you can see the various approaches for the Stellated Dodecahedron.

Here is the one made from two squares. As you can see it’s the simplest of the bunch.

Next up is the one folded from a 2:1 rectangle. This one is remarkably efficient in it’s use of paper, to the point where I had to set it into a larger area to have paper to do the joining. It’s also kind of cool because it has a sort of zigzag layout. I plan to publish an animated CP of this one shortly.

Lastly is the “classic” version, from a single square. This is foldable but very difficult. I like the CP a lot because of the way the layout maximizes the root pentagon and underlying square. Vertices of the finishes form touch 3 edges of the paper. This one would be a good for an animated CP as well.
