Re: Built Models of Compound Polyhedra

Looks to be very well made. Well done!

Yes you can find this in Stella at "Stella Library->Compounds->Cubes 10 B"

Re: Constructing models with transparent faces?

Looks great! And a great example for using such a method.

Re: Constructing models with transparent faces?

Late reply, but I haven't been active on this forum so much (forgat checking actively) Anyway.. The answer is: yes, I did. I made some models of polychora. I use plastic overhead sheets, on which I printed a little bit of colour. One result is here: https://i.postimg.cc/TLq2QptS/Rect5-Cell.jpg Here...

Re: On display in Finland

I wasn't there and haven't visited the Bridges Conference for quite some years. Not even the one in Sweden (where I live). During that time I was hiking in the Swedish mountains up in the North. Next year's Bridges is in Finland again, and I hope I can be there. Nice to see your models, Robert! Sor...

Never seen this one. That is an awesome model, Robert! Is it still in one piece?
Pieces pop out easily if you try to operate it, but it's easy enough to put them back in (hopefully the right way around!)

Thanks Marcel.

The link still works for me. Try it again maybe? Does it work for others?

Re: 4D stellations

Use "Poly->Create Mirror Image". Only available when the base model doesn't have mirror symmetry already.

Re: 4D stellations

When I was working on the 600-cell, after adding a bunch of these cores by using the blend from memory I ran into an error: "Couldn't find exit edge" What does that mean? It means something went wrong when adding lines to the stellation diagram. Could you send me a .stel file of the first model tha...

Re: 4D stellations

Interesting idea. People have asked about support for 4D stellations in Stella, but there would be a lot involved, and beyond the simplest polychora it would get crazy very quickly. However I'd never thought about just supporting the 3D stellation diagrams. Something I should think about sometime. I...

Re: 4D Compounds from verf

Ah, been a while since I did this so I'd forgotten some of how it worked, but turns out I did already add a way to set the dual name in the vertex figure. Just add "cell-of-" at the start of the dual name. The dual of the vertex figure is a cell of the dual. This tells Stella to extract the name of ...

Re: 4D Compounds from verf

I think that's correct, to count compound vertices twice, and corealmic cells twice. They are two separate items that happen to be in the same place/plane. Same happens in 3D, coplanar faces are still two faces. Re 4D dual naming, you mean you'd like to be able to name the dual even when only saving...

Re: 4D Compounds from verf

Hmm, I don't remember, but could just come down to what order the faces are defined in, which causes it to grow each vertex in a different order.
