Near-Miss Johnson solids

Hello there,

I have made a web page about near miss Johnson solids where I am collecting models made by people across the internet.
The models are displayed in interactive windows and the corresponding files can be downloaded.
I have already included the ones available in Stella as well as from ...

Golden Rhombic Polyhedron made from Dodecahedra

Hello there,

I have been playing with dodecahedra and found in the Stella database two Stewart's solids made only with dodecahedra:
a ring of 8 dodecahedra making a rhombus and a triacontahedron.
Based on the observation that this rhombus must be a golden rhombus (with its diagonal ratio being the ...

Re: Dynamic graph of convex polyhedra with regular faces

Hello,
I have updated the loading of the graph. It is much faster and embedded in the main page now.
Please enjoy !

Re: Vertex issue -1.#IND

I have managed to modify the position of some vertices a bit and now it opens/works fine in Stella, the OFF data is still single precision though.
There was no degenerate face whatsoever. I hope it does not happen again.
Thanks you.

Vertex issue -1.#IND

Hello,

I get an issue when loading some off file into Stella. The loading does not go so fine, I get the right number of vertices, edges and faces but
the polyhedron does not appear on screen and all vertices/edges/faces shows some error like values:
1x5valence, radius -1.#IND

Has it happened to ...

Re: Errors with making regular-faced polyhedron

Hello,

Here is the follow-up about my isssues after some discussion with robertw through PM.

The internal error "ConnectEdges(): Could not find mNeigh for edge 19-1." when loading an OFF file is triggered when attempting stellation/nets.
It seems that the polyhedron I work with are not adapted to ...

Re: Errors with making regular-faced polyhedron

Thank you for your answer.

I think (hope) the first condition is met.
I don't quite get the accuracy one, though. I mean, if some vertex coordinate is 0.5, do I have to explicitly write 0.5000000000000000000 with trailing zeros in the off file ? I understand that there may be issues if two ...

Errors with making regular-faced polyhedron

Hi there,

I would like to report two issues:
- an internal error "ConnectEdges(): Could not find mNeigh for edge 19-1." when loading an OFF file
- an error "Could not make faces regular" when trying to make faces regular

Let me explain how I got that.
I usually start by playing with my Supermag ...

Dynamic graph of convex polyhedra with regular faces

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.
I welcome any critics and remarks.
