Hi There, I was interested in using your periodic table of elements graphic in a publication. Would that be possible? Thank you!

Thanks for asking — certainly! Could you please add the standard Wikimedia credit line below so that your readers can find its vector-graphics version, and also be aware of the discussion regarding its accuracy? Cheers, cmglee (talk) 00:10, 30 May 2016 (UTC)

Your image uploads

It is not a good idea to add photographer name into the filename. Credits are given in the image description ("Author"). Regards. Materialscientist (talk) 23:46, 25 July 2012 (UTC)

Hi I note that you have renamed a large number of my and other contributors' uploads under this Commons:FR#reasons:

#	Aim	Examples (old name)	Examples (new name)
3.	Correct misleading names into accurate ones	File:MY_CUTE_MOUSE.JPG File:1BIGGest_nOSE_everS33n.JPG	File:Dutch_pet_rabbit.jpg File:John_Doe_at_concert.jpg

I do not see how prefixing my ID makes it a misleading name. It is certainly not what the examples illustrate. Can you point me to a Wikimedia guideline stating that IDs are not allowed in filenames?

The issue is not credit but to keep the filenames unique. E.g. being a popular subject, there could be any number of images called File:London_Aquatics_Centre_interior.jpg while File:cmglee_London_Aquatics_Centre_interior.jpg is much more likely to be unique and would almost certainly not clash with an existing file.

cmglee (talk) 13:24, 29 July 2012 (UTC)

Thanks for bringing this up. The renames were proposed by user:BaldBoris and I agreed with him, but you are correct that this is not reflected in the renaming guidelines, and you can claim the files should be moved back. I'm looking into the relevant guidelines and will get back to this. Cheers. Materialscientist (talk) 23:00, 29 July 2012 (UTC)

Dice Distribution

On File:Dice Distribution (bar).svg, could you remove the strange numbers on the left that don't line up with the values of the p.m.f.? And maybe move the fractions to the left axis? I would, but I can't get my Inkscape to do anything with it. Dicklyon (talk) 03:31, 29 April 2013 (UTC)

The numbers are not strange at all: they are probabilities in decimal representation (where the scale on the right is in fractions). They are useful to allow different distributions to be compared, as in File:Dice sum central limit theorem.svg. cmglee (talk) 08:58, 29 April 2013 (UTC)

But they're not being used for that, and multiples of 0.02 are strange when unrelated to anything useful. Dicklyon (talk) 19:42, 29 April 2013 (UTC)

Dicklyon, I don’t get what you’re talking about. The axis on the left is a completely normal decimal axis as used in any and all graphs. It is useful for the same reason and purpose as it is in all other graphs. The fractions are nice for the exact value, but the decimals are what give me the real feeling of magnitude. They should stay. — Timwi (talk) 23:11, 29 April 2013 (UTC)

File:MH370 map.svg

An excellent image, Cmglee. But, as my secondary school Geography teacher used to remind us (with tedious regularity): "a map isn't a map without a compass and a scale." I'm not sure you would necessarily agree with that statement. But - is there any chance of you adding a scale? (I think we can guess China is in the North). Many thanks. Martinevans123 (talk) 15:12, 11 March 2014 (UTC)

Thanks for your feedback, Martinevans123. They are valid points for large-scale maps indeed. On maps covering a significant part of the world's surface, however, having a scale would be misleading, as different parts of the map have different scales (the usual problem of representing a spherical surface on a flat plane). I also think that this part of the world is well-known enough that the reader can surmise that north is up. Many other maps on Wikipedia and other sites do not indicate north unless the direction was unobvious or "up" wasn't north for some reason. cmglee (talk) 20:46, 11 March 2014 (UTC)

Thanks. "I think we can guess China is in the North". I see we already have another contributor at that article. I thought your map was very clear. Martinevans123 (talk) 22:14, 11 March 2014 (UTC)

Confusing homonym diagram.

Hello. The diagram you made https://en.wikipedia.org/wiki/File:Homograph_homophone_venn_diagram.svg is a bit confusing. I think it was a mistake to include synonyms in your diagram, as a homonym can never be a synonym. (Homonyms have different meanings by definition) I can see why you wanted to include synonym in your diagram, but it makes the whole thing quite confusing. For instance, it looks like heteronyms are not also homonyms, which is not the case. I think a better idea for a clearer diagram is to not include synonym at all, and instead nest everything under homonym.

I have many an example to show what I mean:

http://i.imgur.com/ITeQLCX.jpg

As you can see the diagram that I have made is not nearly as beautiful as yours. That is why I am contacting you instead of just replacing your diagram. Maybe if you have the time and willpower you can one day update your diagram.

Original rendition

Hello! Thanks for your note. I drew the graphic based on File:Homograph_homophone_venn_diagram.png which also has synonyms. I don't know enough about linguistics to make a judgement call or find appropriate reference. If you can get a consensus on the exact changes required from the English Wikipedia language reference desk, I'll upload a new version. Cheers, cmglee (talk) 23:25, 29 December 2014 (UTC)

Manhattanhenge

Cmglee - I am fascinated by the analysis you did visualizing location of sunrise and sunset at Manhattanhenge. I am trying to establish how close Greenwich Village/Meatpacking District's Gansevoort Street is aligned to the equinox. Have just discovered it is an old Native American trail and having lived in the area 15 years have always noticed the equinox sunsets each Spring and Fall. More detail here at Bolton's 1922 map but if you have any advice, I would appreciate it. I was a little confounded by the Earth System Research Laboratory website you linked to! Info use here w:Jackson Square Park WindingRoad (talk) 16:09, 29 March 2015 (UTC)WindingRoad

Thanks, WindingRoad. That's an interesting question! I took a screenshot of the area on Google Maps and pasted it in an image editor. I found that rotating it clockwise by 1 degree made Gansevoort St horizontal, so it would be most closely aligned on Mar 22, 2015 (solar declination = 0.84°) according to http://www.esrl.noaa.gov/gmd/grad/solcalc . Even better, the next street, Horatio St is almost exactly east-west, so it should exactly align during the equinox — though the trees may spoil the view! cmglee (talk) 19:41, 30 March 2015 (UTC)

Cmglee - thanks for doing that analysis, very helpful, very interesting. I just posted some pics I took before (believe it or not) i fully realized this was so close to the equinox! Unfortunately they are off by a few days, but I think you'll find them interesting, too!

Adjustment?

Could you adjust File:Ordnance Survey National Grid.svg to use a different landmark? It looks to me as if Nelson's Column, for example is slap on the square border, possibly edging over into the next square (TQ 30 80). Perhaps the nearby equestrian statue marking the site of Charing Cross would be suitable.

Rich Farmbrough, 07:06 17 January 2016 (GMT).

Hello, Rich. I like your choice of the statue as it's traditionally where distances to London are measured, as I just found out. However, its grid reference, TQ 30037 80373 still puts it at the edge of a square. I'll think about how I can better present it. Cheers, cmglee (talk) 15:47, 17 January 2016 (UTC)

P.S. This might sound silly, but I like "TRAFALGAR SQUARE" because "TQ" is hidden in it. I suppose I could also pick Buckingham Palace because it has "The Queen"!

I like the TQ/Trafalgar Square too, hadn't thought of "The Queen"! Rich Farmbrough, 22:58 18 January 2016 (GMT).

3d Bubble Chart

Hi,

I am really interested to know the name of the program you used to create that 3d bubble chart of life expectancy for males vs females. Any support either in terms of the code or any other information is gretaly appreciated. Thanks. You can reach me at: stat4everman@gmail.com

John

Hi John, the program is a one-off Perl script embedded in the SVG file itself. If you open http://upload.wikimedia.org/wikipedia/commons/b/b2/Comparison_gender_life_expectancy_CIA_factbook.svg in a text editor, from near line 4000 to the end of the file is an SVG comment ( <!-- --> ) containing the script. Extracting and running it generates the SVG file. I've since moved on to Python — see en:user:cmglee#animal_hearing_frequency_range.svg_.E2.98.8E_26_Oct_2014 — but if you've any questions about this script, just ask!

Read the video description:

If "GMG NETWORK ORG" does not own the rights of the video,"GMG NETWORK ORG" can not release it under a creative commons license.

If it was released at some point under Creative Commons License, "GMG NETWORK ORG" forgot the attribution/source.

In both cases, we can not use the frame grab.

I am very very sorry. It is a valuable picture illustrating an idea, that makes the world a better place.

That is why am sad and sorry to request the deletion. But with the unknown original source, the image it self is a copy right risk.

File:Comparison optical telescope primary mirrors.svg

Hi, your graphic of the large primary mirrors is really well made and accurate. It lacks a little something though, the Five hundred meter Aperture Spherical Telescope (FAST) which China is building and will complete in 2016. I figure it won't be too difficult to add since it's just a curved line at the bottom. I don't know if it will even be relevant because it will maybe look like a straight line, but since it will be the largest telescope in the world, I think it has its place. Thank you and good job on your great graphics. --Piponwa (talk) 21:19, 11 May 2016 (UTC)

Hi @Piponwa, Thanks for bringing FAST to my attention. It's a radio telescope whereas the graphic is about optical telescopes. Arecibo was put in as a comparison because it is well-known. I'll keep it in mind if I decide to make one on radio telescopes. Cheers, cmglee (talk) 11:53, 12 May 2016 (UTC)

Doing one on radio telescopes would definitely be cool, I feel like the more quality material there is, the more people are going to be excited about telescopes. Thanks for all that you do! --Piponwa (talk) 15:19, 14 May 2016 (UTC)

I've been looking through the SVG images you've created and they're very impressive. I actually saw the comparison of bridges one in the past and was surprised SVGs could do that.

A small mistake?

First, thank you for your work.

Second, I think I might have found a small mistake in one of your additions: https://en.wikipedia.org/wiki/File:3D_shapes_in_isometric_projection.svg

In the cube there is a measurement that says sqrt(3) and I believe it should be 2*sqrt(3), I haven't checked the others, but I just happened to notice that.

Sorry if I am wrong.

Hi @Sempiedram, Thanks for your feedback. I think √3 is correct. One way of looking at it is to consider that the cube appears as a regular hexagon made of 6 equilateral triangles of side 1. Looking at the top-right one, its top most angle (the one just under the 3 of the √3 label) is 60°. As the top-right side (hypotenuse) has length 1, the horizontal width of the triangle is sin 60° = √3/2. Hence, the total width of two of these triangles back-to-back is √3.

Spherical panorama

Hi,

I'm curious- what device did you use to take the above image? Andy Mabbett (talk) 19:19, 10 July 2016 (UTC)

Hi Andy,

Just an old Nexus 7 (using the Photo Sphere mode of the native Google Camera app, then converting to a Tiny Planet projection on the same app). Alas, there are plenty of misstitches due to my handholding it... Are you planning to snap some yourself?

Cheers,
cmɢʟee⎆τaʟκ 19:48, 10 July 2016 (UTC)

Thanks. Yes, I'd like to have a go. You might like to use Category:Taken with Nexus 7. Andy Mabbett (talk) 10:54, 12 July 2016 (UTC)

Good idea – done!

You're probably aware of these but if not, here are some techniques for better results:

1. Choose scenes far from the camera to reduce parallax – best are landscapes, but at least stand up and stay away from railings.
2. If possible, choose scenes without obvious geometric patterns e.g. large floor tiles and roof beams.
3. Avoid taking a shot when moving people are in the scene to avoid half bodies.
4. Pick an identifyable point on the ground and try to keep the camera over it.
5. Pivot around the camera rather than standing still and turning the body; I grasp the device around the lens with one stationary hand and use the other to swing it around the pivot.

Shame I discovered them only as I went along, but I suppose one gets better with practice... Good luck :-) cmɢʟee⎆τaʟκ 11:31, 12 July 2016 (UTC)

Useful tips, thanks - why not write them up at, say, Commons:Polar coordinates panoramics, so others can benefit? Also, sadly, the Google Camera page on the app store tells me "Sorry! This content is not available in your country yet." :-( Andy Mabbett (talk) 20:06, 16 July 2016 (UTC)

I could do that, but I'm uncertain about Commons' policy; I know Wikipedia discourages How-to articles. Strange it complained about the country; mine came preinstalled. I suppose you could sideload it with adb, or find another app? Alternatively, just snap enough coverage and use AutoStitch (easier but less control) or Hugin (lots of options but a pain to use). After watching a clip on Hololens today, I had a thought that spherical panoramas would be a useful application, if only there was a good way of navigating between panoramas.

It's a "prosign"! This particular one is KN, with the overscore denoting that K's dahdidah is followed directly by N's dahdit without the standard pause. There are a number of such prosigns, and the meaning of this one is "go ahead, specific named station", which is a less-than-perfect fit, since linking to my Talk page is perhaps more akin to inviting someone over to a different frequency, but I think the overall tone of the message is right. —jameslucas ^{▄▄▄ ▄ ▄▄▄ ▄▄▄ ▄} 11:45, 18 May 2017 (UTC)

Pyramid SVG

I really admire your Comparison_of_pyramids.svg and Comparison_of_pyramids_SMIL.svg images of many of the most famous pyramids around the world.

I don't have any experience with SVG files, but was wondering if you might consider updating them to include Monk's Mound at the UNESCO Cahokia site. It is considered the largest pre-Columbian site of its size north of Mexico. It has been damaged considerably by less-sensitive early European settlers, but Monk's Mound remains. It stands at about 30 meters so on the smaller side by height, but the base is similar in size to the Great Pyramid. Monk's Mound was also probably taller when the area was inhabited prior to European settlement, given that it is earthen like some of the Chinese pyramids.

Thanks for your work and consideration, --24.148.29.243 23:47, 30 July 2017 (UTC)

Box-Muller Transform SVG

Fixed

Hi Cmglee,

Firstly, thanks for the excellent SVG of the Box-Muller transform.

Would it be possbile to have the round points (U0, U1) start at 0 and go to 1, so that (0,0) and (1,1) can be selected as points? That way it's easier to see the transformation because cos(0) = 1 and sin(0) = 0.

Diagram of Integrating Sphere use in measuring transmittance and reflectance

In the first part of the figure, dealing with transmittance measurement, shouldn't the bottom port simply be plugged (i.e. covered with the same material as the rest of the inside of the sphere) rather than being fitted with a reflectance standard? 72.89.126.128 08:09, 8 November 2017 (UTC)

Hi @72.89.126.128, I assume that the reflectance standard is opaque and fills the port, in which case, plugging it is redundant. If it weren't, plugging it would be a good idea.

I just discovered your CSS-animated Haiwaian map. As a cartographer I find this purely fabulous.

Thanks, Yug. I'm unsure how much detail I should go into, so let me know if you'd like me to elaborate on the steps below:

1. Extract paths of contours from an existing SVG, File:Hawaii_Island_topographic_map-en.svg in this case.
2. Assign each path to a class with CSS3 animation (360° rotation).
3. Scale each rotating class by half vertically and progressively translate them to give the appearance of 3D.
4. Add special effects e.g. the wavy surface denoting sea level.

Thank you for creating a graphic for the different brick sizes over the world. One correction that needs to be made is changing the word "nominal" to "actual" since that is what is shown in the associated table. Nominal is the actual size of brick plus a mortar joint thickness. The table lists actual sizes. Also, you should consider deleting the word "house" brick since the brick shown in the table and your graphic can be used in buildings as well as homes.

Requesting help to fix SVG

Hi there, it's been a while. Since it's election season in Malaysia, I've emerged from the proverbial cave to upload another SVG related to the topic. However, the text doesn't look quite as well as this one. Have they changed the SVG rendering, or have I left out something in the stylesheet or XML namespace?

Also, I'm sure some parts of my SVG code are redundant, such as reusing colours. I couldn't think of an elegant way to do it without breaking the neat format you have introduced. Can you help on this? Thanks a bunch! Hytar (talk) 07:44, 16 April 2018 (UTC)

Dewan Rakyat 2013 Equal Area (changes).svg

Hi Hytar, thanks for updating the graphic – good work! I've updated the file after

1. Moving the class to the top of the stylesheet – there's a small chance that the stylesheet has a bug before the word class preventing the class from being parsed and the text reverting to the default style (I don't see any bugs when eyeballing it,
2. Turning style tags with colours into classes, and
3. Aligning columns of numbers etc

I've no idea why the font looks different even though both SVG specify 14px normal Bitstream Vera Sans, thought I've previously encountered Wikimedia thumbnails being broken, often because the XML header was incorrect (it's fine in this case) or the renderer had temporary issues. The latter often cleared up after a few days, so it might be worth clearing the cache and rerendering it by adding ?action=purge at the end of the URL.

As a side note, I normally specify "Helvetica,Arial,sans-serif" instead of Bitstream Vera Sans as I think it's more likely that users have these fonts, should they wish to view the SVG on their browser.

Hope that helps, cmɢʟee ⋅τaʟκ 13:03, 16 April 2018 (UTC)

P.S. I find the colours (especially the faded versions) of PKR, Warisan and Independent, and DAP and PPBM hard to distinguish. Not knowing Malaysian politics well, I cannot recommend alternative colours, but how about increasing their colour saturation, or adding subtle versions of their symbols in the hexagons?

Thank you for your fixes! I have uploaded another version after changing the colours a little. At first I'm basing all colours on this template, but the faded colours (under "/shading" in templates) are more suited as background for text, and seemed too bright for map use. Hence I stuck with the previous colour template from 2008 and adjusted from there. I might tweak them some more to find the "best" palette, but for now I'll put the image into this article.

As for the text, I removed other properties deemed extraneous and used "sans-serif" as font. They are readable even though they look a little off, so I'll give it a pass. Hytar (talk) 18:14, 16 April 2018 (UTC)

Thanks, Hytar. That's clearer. I'd prefer to specify a widely-available font, though. Otherwise, people who have a very different-looking font assigned as sans-serif will see it garbled. I think Helvetica,Arial is a good choice for wide support and acceptance, and neutral appearance.

A nitpick: I noticed that "general election" is in lowercase where it's in title case in the previous image. Cheers, cmɢʟee ⋅τaʟκ 12:05, 17 April 2018 (UTC)

I prefer it to be lower case "general election" following the convention on Wikipedia article titles. That means I need to change the 2013 file, which I try not to; but you can change it if you want, including your suggested font change.

Eventually I'll touch the parliament "changes" file and will take your suggestion into account. In the meantime, I need to work on three files:

• State assembly/DUN changes file — more work due to increased Sarawak seats in 2016.
• Base SVG for 2018 parliamentary election — easier because seat number is retained, only name changes and additional parties required.
• Base SVG for 2018 state assembly elections — "changes" file in item 1 plus increased Sabah seats.

Very impressed with images

I am curious about their creation. I read you've used Python in the past. Do you have any additional information, or some code of how you went about it? I've been interested in delving into a similar project myself. The possibility of controlling a complex visualization programmatically seems like it opens up many interesting doors. I was particularly impressed by the visualization of the binomial theorem (up to the 4th power). I'm well versed in software and Python, so please feel free to be as technical as necessary. Thank you very much for any information, and for the wonderful contributions. (talk) 04:18, 19 August 2018 (UTC)

Thank you for your kind words, ‪Rmiguez0‬. My Python code comprises standalone scripts which output SVG files with the Python code embedded. I wrote short articles on my almost-polyglot SVG-generating Python code and improved its handling of format strings on my Wikipedia user page.

I've since split the generated SVG into two parts: definitions and the main body. If you'd like to see an example, download https://upload.wikimedia.org/wikipedia/commons/2/2a/Plato_number.svg and look at its contents. Does the above help answer your question? Let me know if you'd like to work on an illustration together. Cheers, cmɢʟee ⋅τaʟκ 23:58, 19 August 2018 (UTC)

A barnstar for you!

	The Graphic Designer's Barnstar
	I was so impressed by one of your images (water phase diagram) that tracked other work you have done. Now I have a folder full of amazing images. I am a teacher (Earth Sciences) and like to use visual aids. Your work prompted me also to read enough about how to properly attribute CC... Thank you for the work you do. VBIK (talk) 16:39, 9 October 2018 (UTC)

Thank you so much, VBIK – that's the kindest thing someone has told me in a long time!

I love spreading useful knowledge and as I wrote on my Wikipedia user page, I'm eager to illustrate science, technology, architecture or mathematics, and always on a lookout for ideas. Please let me know if you know of anything that can be better explained in a diagram.

Best wishes in your teaching,

File:Volcanic eruption map.svg requires updating

Hi Cmglee,
Thank you for your contributions to Commons. I noticed File:Volcanic eruption map.svg is out of date. Could you update it? Thanks again. (And sorry for the somewhat blunt automated message!) OwenBlacker (talk; please ping me in replies) 16:45, 14 December 2018 (UTC)

File:Voyager 2 velocity vs distance from sun.svg

Hi

Thank you for all your excellent work. I have a query about this file https://commons.wikimedia.org/wiki/File:Voyager_2_velocity_vs_distance_from_sun.svg

Perhaps I'm wrong but the shape of the "solar system escape velocity" chart in blue looks wrong to me.

I tried to make a version in Excel and it looks quite different (I'm afraid I can;t manage to upload it). My chart is based on the escape velocity changing as one over the square root of the distance from the sun. I wonder if you have used some other formula?

I came across this via this Quora answer: https://www.quora.com/Escape-velocity-from-the-Sun-is-42-1-km-s-but-Voyager-2s-maximum-recorded-speed-is-16-km-s-How-did-it-reach-interstellar-space-What-am-I-missing/answer/Joshua-Engel

Kind regards

Thanks, David. Your concern had already been raised on File_talk:Voyager_2_velocity_vs_distance_from_sun.svg. As I replied, since the data was taken from the graph at the NASA site, I am rather reluctant to change it without further evidence from an equally or more reliable source. (Other factors besides r² losses may affect it.) Cheers, cmɢʟee ⋅τaʟκ 03:11, 24 December 2018 (UTC)

Planetary Elevation Models

Hi There,

I love the work you have done so far with the planetary elevation models so far, particularly Mars. Unfortunately the Wikipedia page for downloading the STL seems broken. Would it be possible for you to upload it to a separate file-sharing website for us to download?

(As a note on this, what program did you use to create it/can you change the height scale (currently at 20x) easily?) —Preceding unsigned comment was added by 62.252.189.68 (talk) 19:49, 7 January 2019 (UTC)

Thanks! It seems to be working for me. Note that each is over 20 MB, so it might take a while to download. Another way to view them is by clicking the viewstl button e.g.

View https://upload.wikimedia.org/wikipedia/commons/c/cd/Mars_elevation.stl  on viewstl.com

I wrote a Python 2 script using PyPNG to create the STL from a heightmap in PNG format. Here is the source code. By changing the variables at the top of the script and the heightmap, one can tweak the model. The one you asked about is exaggeration. The script is described at en:user:cmglee#Mars_elevation.stl_☎_1_May_2018. Do give it a go!

Cheers, cmɢʟee ⋅τaʟκ 00:50, 9 January 2019 (UTC)

Thank you very much for linking the code! I have got it up and running, however struggling to track down a suitable image to use. Do you have a link available to the image that you ended up using, or any guidelines for what sort of image works best? From the code I have seen that they need to be 1-channel equirectangular, but what about colour/BW?

EDIT: The link is unavailable (I assume due to the current government shutdown in the US). Is there a way to for you to upload the image you saved to use? —Preceding unsigned comment was added by 54.37.18.131 (talk) 19:55, 11 January 2019 (UTC)

Thanks again —Preceding unsigned comment was added by 54.37.18.131 (talk) 19:51, 11 January 2019 (UTC)

Hello! Here's an archive of it in JPEG format. Convert it to an 8-bit greyscale PNG and feed it into my script. There's a higher-quality TIFF version, but it fails to download from http://astrogeology.usgs.gov/search/details/Mars/GlobalSurveyor/MOLA/Mars_MGS_MOLA_DEM_mosaic_global_463m . If you want to use your own heightmaps, they must be full-planet equirectangular 8-bit greyscale PNGs with dark being low elevations. The variables at the top of the script determine the scale and spheroid eccentricity. http://google.com/images?q=heightmap+filetype:png has some you can try. Good luck! cmɢʟee ⋅τaʟκ 14:04, 18 January 2019 (UTC)

{{Svg lang}}

Hi. Currently all thumbnails in a {{Svg lang}} template just link to the SVG file, which is quite redundant. I'd prefer having a link to the corresponding ?lang=xyz page on Commons. Would you mind, if I changed {{Source thumb}} accordingly? Is {{Source thumb}} used anywhere outside of {{Svg lang}}? Thanks. TilmannR (talk) 19:46, 3 March 2019 (UTC)

Good idea, TilmannR; please go ahead. It's used in many derived images to show the original image, but if the default has the same behaviour, there should be no problem. Cheers, cmɢʟee ⋅τaʟκ 00:04, 4 March 2019 (UTC)

Oops, I don't think I got notified of your reply ({{Ping}} seems more reliable than {{U}} for this purpose), so I went ahead and created my own Template:Lang gallery, which has the disadvantage of having smaller thumbnails, but looks exactly like any other <gallery>, which is nice. (E.g. File:Bobo_doll.svg#Summary)

Regarding "the default has the same behaviour": Do you mean "the default has the same behaviour as the non-default" or "the default has the same behaviour as before"? Currently it links to the Commons page, but I can make it link to the raw file, if you want. TilmannR (talk) 10:20, 5 March 2019 (UTC)

And I have a small question. I don't have much experience with template development, so I don't know where I can look this up: If you have a template A within a template B on a file page F, does {{PAGENAME}} evaluate to the name of B or F? The first version of {{Lang gallery}} didn't work (the {{Lang gallery/thumb}} were invisible) and passing {{{file|{{PAGENAME}}}}} to {{Lang gallery/thumb}} fixed it. On the other hand, if the file name had simply been invalid, I would have expected the thumbnail to be a redlink and not invisible. Not sure how to debug this. TilmannR (talk) 10:32, 5 March 2019 (UTC)

Never mind. The actual problem was that I tried to pass an empty first parameter, which automatically turned the second parameter into the first parameter and made the second parameter empty, which made the template invisible. TilmannR (talk) 10:54, 5 March 2019 (UTC)

Never mind. The actual actual problem was, that {{{1|default value}}} doesn't yield the default value, when 1 is empty, but not undefined. I really should have read meta:Help:Template before writing that template. TilmannR (talk) 20:47, 5 March 2019 (UTC)

Hi @TilmannR:, sorry for the slow reply. Template:Lang_gallery looks great! Re Do you mean "the default has the same behaviour as the non-default" or "the default has the same behaviour as before"?, I meant the latter. I'm happy to have your new template replace my old one, if you like. Cheers, cmɢʟee ⋅τaʟκ 18:33, 18 March 2019 (UTC)

Oh, weird: I didn't get alerted about the ping either. Also your "thanks" are linking to the specific edit, for which you thanked me, so I completely missed your reply. I changed {{Source thumb}} to link to the raw file, when no language is specified. Makes sense: There are still links to the file page and its #filelinks section, so no functionality got lost. I actually came here to talk about mars elevation... TilmannR (talk) 12:27, 24 March 2019 (UTC)

Mars elevation STLs

Hi. I noticed that Mars elevation.stl is not quite optimal.

1. The data is "planetocentric", so I don't believe that using a "WGS84 flattening factor" is actually correct. I'm not 100% sure though.
2. If you look at a smoothly shaded version of the file, it becomes obvious that the positions of the peaks of your little pyramids aren't correct.

View Mars_elevation.stl  on viewstl.com

I uploaded Mars elevation 2.stl yesterday. It's not quite finished, but I already like it a lot. It's generated via an embarrassingly brute-force method: I use a normalized subdivided Deltoidal icositetrahedron as a base mesh, which leads to more uniform triangle sizes than using a normalized subdivided cube. Then I took nearest-neighbor-interpolated (i.e. not at all interpolated) altitude samples from megt90n000fb.img for a 207.4 MB STL. Finally I decimated the file to a tenth of its original size in Blender. Originally I intended to use an adaptive subdivision approach, but decimation (while being extremely slow and memory intensive) gives excellent results, so I don't feel motivated to do that much additional programming. My texture coordinate calculation seems to be off by one, which causes a small hole in the south pole. A "south hole", if you will. I'm thinking of doing iterated subdivision and decimation to reach an even better mesh. And I should probably use a smarter sampling method for the altitudes.

P.S.: I don't have time to do this right now, but {{Viewstl}} should have an optional parameter for passing a file name instead of a complete URL. TilmannR (talk) 13:18, 24 March 2019 (UTC)  Done TilmannR (talk) 18:45, 24 March 2019 (UTC)
