Great Stella


After finally persuading my Dad to let me get it, I now have my own copy of the program Great Stella! Great Stella is one of the only available computer programs for viewing and printing out nets for polyhedra. But it can also stellate, facet, truncate, augment, and much more. Great Stella is the second in a series of polyhedron-making software by Robert Webb. The first, Small Stella, comes with a library of about 300 polyhedra and can print out nets for all of them, but cannot modify them at all other than changing their size. Great Stella has the capacity to, as I mentioned earlier, play around with the models quite a bit. It also comes with a built in library of several hundred polyhedra, including many not included in Small Stella. And finally, there is Stella 4D, which is a lot like Great Stella, but also can handle 4-dimensional models. Wait, 4-dimensional? Sounds like something out of a science fiction novel, right? Technically, though, there is no way of proving that the fourth dimension doesn't exist (I think), and besides, four dimensional objects (projected into our familiar three) look really cool. And who knows? Maybe we are just poor shortsighted three dimensional beings wandering around on the three dimensional surface of a four dimensional hypersphere. But I digress.
So far I have made one model with nets from Great Stella, the compound of four cubes. My model is in red, yellow, orange, and black, with an edge length of 3 inches (so a diameter of about 5.2 inches). I will get a picture of this model up soon. The model matches my compound of 3 cubes in edge length, and I am currently building a compound of 6 tetrahedra with an edge lenth of three inches as well.

Hey, N., i was wondering what book is Lilith? I looked it up but...

It's by George Macdonald (if that means anything). I read it and loved it. To tell you the truth, though, I don't remember that much of it. I really ought to read it again.

Hey Question. What dimension is Time? After all If a figure had no "duration" would it actually exist? There's length (1st) width (2nd) and depth (3rd) but then if it did not exist for any length of time... (and I don't mean infinity either).

The "great disnub dirhombidodecahedron" should obviously be considered a polyhedron, if only because it has an abnormal name. Which completely qualifies it.

Hey, that Great Stella, or whatever it's called, looks interesting. I'd never, in the history of my life, be able to work it.
I don't like long words I can't pronounce...

Hi Nate! Your blog sounded intriguing...so here I am! I am not the best at math but good for you!

Hi Rose its me (from St. Mary's Picnic)...I will have to e-mail you!
