Welcome to WikiProject Polyhedra, the WikiProject that aims to improve Wikipedia's coverage on polyhedra!
Polyhedron of the week[edit]
Uniform polyhedra |
Please help improve these articles:
- Get our coverage of all 75+1 uniform polyhedra to a reasonable level, covering all aspects of each polyhedron in its article. Some prisms and antiprisms (especially 3-, 5-, 6-, 8-, and 10-gonal prisms, and the pentagonal antiprism) wouldn't hurt either – these would be a great help for our uniform polychora coverage.

Tasks[edit]
- DONE: Create stubs on all uniform duals.
- Completed to an inconsistent minimal stub level, list at Template_talk:Nonconvex_polyhedron_navigator Tom Ruen (talk) 22:20, 16 September 2009 (UTC)
- DONE: Add infoboxes
- I tested a minimal statbox using uniform database, tried at Tetradyakis hexahedron. The main useful thing missing for the duals is images of invidual faces (polar inversions of the uniform vertex figures). They are given at [1]. I can generate them, maybe can run a batch process in the next week. Tom Ruen (talk) 22:37, 16 September 2009 (UTC)
- If anyone wants some useful "busy work", you can add templates to ALL dual uniform pages:
- Go to a dual uniform article (Second list at Template_talk:Nonconvex_polyhedron_navigator), example Octahemioctacron
- Click on first sentence link about its "dual" to get to the uniform article and edit, copy template from the top: example Octahemioctahedron, COPY: example { { Uniform polyhedra db|Uniform polyhedron stat table|OhO } }
- Go back to dual uniform article and edit
- Remove image on top (It'll be in the template table)
- Paste template copied, and insert word "dual", and "save page", PASTE AND EDIT: example { { Uniform polyhedra db|Uniform dual polyhedron stat table|OhO } }
- This will allow changes in the database Template:Uniform polyhedra db and changes in the stat-table Template:Uniform dual polyhedron stat table to affect all dual article.

- User:Robert Stanforth completed this. Thanks! Tom Ruen (talk) 23:49, 19 September 2009 (UTC)
- Make a template for all uniform polyhedra and uniform duals in the form of Template:MinorPlanets Navigator.
- Complete Stellation model images at The_Fifty_Nine_Icosahedra (Using Vladimir Bulatov's Applet at: [2]. George Hart also lists them all at [3]) (About 38 of 59 are missing)
- I added links to all 59 of George Hart's VRML stellation models, helpful at least until all images are added! Tom Ruen (talk) 05:40, 21 September 2009 (UTC)
- All images added using Stella. Double sharp (talk) 04:51, 7 October 2012 (UTC)
- I added links to all 59 of George Hart's VRML stellation models, helpful at least until all images are added! Tom Ruen (talk) 05:40, 21 September 2009 (UTC)
- Help needed on Sonobe please! Sonobe modules are origami shapes used to construct polyhedra. I have Wikified the page and added the history, however the maths bits are unreferenced and beyond my ability to reference accurately. Ninquelosse (talk) 10:33, 18 October 2014 (UTC)
- Add 3D models to all polyhedron articles, including the uniform polyhedra (and compounds), Johnson solids, stellations of the icosahedron, and other special shapes. I and TilmannR have already created most of these, and I'm working on some of the missing ones (pyramids, antiprisms, trapezohedra and the uniform compounds). It's just a matter of adding them with a short description such as "3D model of [shape name]". For convenience, I've been compiling these models on my userpage, where a download link with all the GGB and STL files I've made can also be found. – OfficialURL (talk) 03:45, 12 April 2020 (UTC)
- Add coordinates for all the Johnson solids. Wolfram Mathematica (and by extension WolframAlpha) gives coordinates for the n-th Johnson solid with the command
PolyhedronData[{"Johnson", X}, "VertexCoordinates"]
. To cite them, based on their support page, one should use
- {{Cite journal|last=Wolfram Research, Inc.|date=2020|title=Wolfram{{!}}Alpha Knowledgebase|location=Champaign, IL|quote=<code>[CODE]</code>}}.
- If they eventually add info on (more of) the uniform polyhedra, we could also use them as a citation there. – OfficialURL (talk) 03:45, 12 April 2020 (UTC)

- Tomruen - no promises!
- Steelpillow - may be a bit come-and-go.
- Robert Stanforth - special interests include uniform polyhedron compounds, and proofs of enumeration
- Tetracube - visitor from 4-dimensional Euclidean space
- Double sharp - special interests include uniform polyhedra, stellation and faceting.
- Stannic — building the database of tessellations on Wikimedia Commons while I have time for it.
- RobertLovesPi -- Will work on improving clarity and accessibility in polyhedra-related articles. Also may begin replacing numerous unmoving polyhedral images made with Stella 4d with otherwise-identical rotating .gifs made using the same program. If anyone thinks this is a bad idea, please shoot me a message to that effect.
- Alberto79
- KingAntenor There is definitely some potential here.
- OfficialURL (talk) – I'll be adding 3D models to all uniform polyhedra and Johnson solids (credit to TilmannR for creating many of these in the first place), as well as translating many pages to Spanish.
- هيربد فودازى٢ (talk) 09:11, 6 July 2021 (UTC)-I'll mainly improve pages in Persian Wikipedia.
