Zonohedrification can generalize into any dimension except 0D, add it in the next update.

Some recent models using 3D-printed connectors for K'nex rods. Connectors modeled in OpenSCAD using vertex angles from Great Stella....

I put together a little puzzle, to count intersecting cubes. You can test your answers and I just added hints in the form of colours.

Let me...

I found this polyhedron while going through facetings of the snub tetrahedron/icosahedron. Has anyone seen this before? I find this faceting to be...

Hello people from the Stella community,

Long story short, here is a graph of all convex polyhedra with regular faces.
I hope you will enjoy it.

Just finished a new paper model, the small snub icosicosidodecahedron:

New member with interest in making, via CNC, wooden models of the various shapes.

Would appreciate contact with other members with similar interests

Two of my models were accepted for display at the Bridges 2016 conference in Finland in August, as shown below with a picture of one of them being...

Would it be possible for Stella to explore plane tilings as well as polyhedra?

There seem to be two approaches to tiling:

Symmetries (e.g....

Hi Rob,

Apart from doing a screen/window capture is there any way of retrieving the information in the Great Stella info window? Appreciate that...

Where you can find models of polyhedra crystallography? (cubic, trigonal etc)
They are available in stella?
thanks for the reply
thx

Hi, I am looking for a way to get polyhedra as vector out of Great Stella.
DXF export and import in AI/CDR X6 is what I already have tried but

One feature that would be quite useful would be the ability to rotate and move a part of a compound. This could be used to produce interesting...

Just bought Great Stella4D. Happy to join the club of symmetrists. Having built quite a few models over the past years I am ready to tackle the...

Here's a couple of not-quite near misses I created recently. They're like near misses, but maybe not quite close enough to earn the title. They're...

Hi

I've just spent a frustrating couple of hours trying to find an app that could display Stella4D 3D models on my original iPad running iOS 5.1.1....

Hi folks,

I have just created a facebook page for Stella, so if you're a facebook user, feel free to like it and help get it started.

Thanks!...

Back in 2003 there was a story about Great Stella on TV.
You can see a bunch of my paper polyhedra here too.

Rob.

At this site you can buy a 3d model of carved elements, such as:
Carved arches, carved moldings, carved coats of arms, carved capitals, carved...

This thought started a few days ago when I thought I'd try and export images of each stellation of the icosidodecahedron. I noticed there wasn't...

Hi Rob.

I've discovered a new stewart toroid!
Basicly K5 / 12Q5 S5 (E5) + 20 (R5 / S5 Q5)

Just bought Stella4D, will be using it to cut facets on my CNC machine thence to make wood realizations of the various shapes. I build furniture...
