Currently Stella doesn't print tabs on nets. Do people think it's important that tabs should be printed? The FAQ has the following: Q: Are tabs printed on nets? A: No. Maybe someday, but I don't think it's too important. You just need to remember to leave tabs on edges as you cut out the nets. There...

Good idea Ulrich. Here's a pic in case anyone can't follow this: http://i225.photobucket.com/albums/dd237/RobertCWebb/SubdivIcos.gif Use "Poly->Subdivide Faces" to get the tesselation required. You're right that this will only work in this case. For a dodecahedron with one vertex truncated, dividing...

I used (and almost always use) 120gsm paper. I found 160 was just a bit bulky, but weight doesn't always correlate to thickness. Actually I think the more recent paper I got was 140gsm which was fine. My model has edge length 2cm, giving the model a diameter of about 10.5cm. Yes, it could have used ...

Yeah, an undo button after hitting a mine would be handy, and yes it would have to disable high scores for that game. Has been on the to-do list for a while, so maybe sometime. Don't know about the "am I missing something" button! MineSweeper3D can already show you a hint for the next move (which al...

That's the zonohedrification of the dodecahedron. Just load a dodecahedron in Stella and hit "z" (or "Poly->Zonohedrify").

Stella can then print nets for you, and show angles if you need them. Here's one I made out of paper:

I don't know what to call that shape. It reminds me of a Moebius strip, but obviously isn't. It's really a torus with a lateral wave through it. I'll ask around, but maybe it has no name.

Actually there is no way to define edges in an OFF file, but yes you often don't need to define cells (although sometimes you do). I'll make it possible to load a vertex-only 4D OFF file at some point. If you just want a convex hull of the verts, you're not going to want to figure out how to link th...

Not sure, but Stella can take an .OFF file as input, so if you have any programming skills, you may be able to write a program to output a helix in OFF format. See http://www.software3d.com/StellaManual.php?prod=stella4D#import and http://www.geomview.org/docs/html/geomview_41.html Something occurre...

IF I ROTATE EACH 10 degree SLICE/SECTION SAY 2.5 degrees.
WHEN ASSEMBLING?

If I keep everything aligned (NO ROTATION) then I produce a torus.

A helix?

Hmm, pretty weird-looking board, and a meaningless shape to most people.

Rob.

I would like to see a nice open torus (perhaps a genus 1), where it is easier to see what you are doing. Like taking an Icosidodecahedron (ID), and excavating two triangular hebesphenorotundas (J92) from opposite ends. That's quite a nice model. Probably still a bit hard to see how some of the tile...

Interesting idea, and maybe not too hard given the code I already have to start with. How do you see it working? Would the view be of the whole shape like in MineSweeper3D, with say the closest point (or a bit above) being your current position, then you turn and move with the mouse? Or would the vi...

Maybe, although I thought there were other ones like that which worked (been a while since I looked at this stuff). Send me the .stel files anyway and I'll have a look.

Rob.

No, Stella4D inclused all known uniform polychora, but not all the scaliforms, so please send them through if you make any

Rob.

It can indeed be done in Stella, although it was a little tricky.

Once in Stella you can print out the nets
