Hmm, not sure. Yes, Stella does store the edge traversal in its .stel files, so once it's right it should stay right. But coincident faces cause all sorts of problems during Stella's processing (figuring out how to traverse edges, figuring out the symmetry group etc). It usually does ok, but this mo...

Enumeration of stellations (by Miller's rules)

Some of you may know the page where I list the number of stellations, by Miller's rules, for many of the Platonic/Archimedean solids: http://www.software3d.com/Enumerate.php Well, I got an email from Marc Newin, with a new result not presented in my table! A count for the number of reflexible stella...

Hey, thanks for the review. This forum was looking pretty empty :roll:

To keep things relevant, I've posted a response to your feature requests in the Feature Requests forum: http://software3d.com/Forums/viewtopic.php?p=300#300

Thanks,

Stella wizard?

These feature requests were mentioned in a post on the Reviews and Testimonials forum : * I think it would be good to have a 'quick start' or 'highlights' section in the library, to lead the new user directly to some of the prettiest and most impressive polyhedra. Yeah, I wonder if being more friend...

why does yours have so many homes compared with the Stella one? I think you mean "holes" :wink: This is Ulrich's style, to leave holes in the faces so that the inner parts can also be seen (the parts of faces normally hidden within the model). I believe Ulrich uses Stella's stellation features to c...

Nice stuff :D

So these were rendered with Lightwave? What format are you exporting from Stella? .OBJ?

Re: A Duality-related Question

In general, no. It's one of many things that only works for Platonics. The technique can be generalised, but the faces may change (generally to their duals, which are the same for regular polygons). Have a look at Stella's "Morph Duals by Truncation" view. With the cube, at 50% you'll see the cuboct...

Given the many, many polyhedra available, can anyone recommend an interesting one with lots of hollow spaces? (And tell me where to locate it in the menus!) The Stewart Toroids are a good place to start. Select "Stewart Toroids" from the category drop-down list in the toolbar (initially showing "Pl...

Re: Funny pointer

That's odd. Never does that to me, but I know what mode it is (I think). It happens while you hold the Space bar down. Hold down the space bar and you'll see the cursor change as you described. But I don't know how you got stuck in that mode, presuming your Space bar doesn't get stuck down! My guess...

I hope you will consider auto export sequences for a future release - I'll have to try and tempt you by doing something impressive manually! I don't doubt it could be impressive, along with direct export of video. Currently though the only way to see the animations is within Stella. If people start...

Re: A few questions...

I am mainly interested in the export of objects for use in 3d graphics software. I see some great possibilities for 'chrome' models, or sticking a volumetric light at the centre of the ones with holes, or even using refractive glass! You can see a few examples of ray-traced renderings from Stella h...

Paper: 65 pound acid free card stock (sorry, I'm not used to the metric system!)

Re: Cundy & Rollett

This sounds like it might be Cundy & Rollett's Mathematical Models , which describes the construction of the five cubes compound in just that way. (On the other hand, that book was not necessarily for young readers.) No, it was not that book. It contained larger nets that you could trace off and us...

Re: Cundy & Rollett

If you use double tabs and continue the tabs where the edges form pentagrams - do it pin-wheel style with 5 sets of double tabs, each holding two pairs of triangles (and thereby bracing each octavalent re-entrant vertex) - the model is so rigid you would not believe it! I'd believe it (although I g...

Re: Ten grand stellated hecatonicosachora

Compare, say, a great stellated dodecahedron with a single one of its two-dimensional cross sections, which might typically be a few interpenetrating polygons. And just for fun, here's a cross-section of the great stellated dodecahedron , taken at the 0.555 depth that George has grown fond of: http...
