major and minor radii
[edit]Are these synonyms for semimajor and semiminor axis?
Independently, what can and the major radius is the geometric average between square and circle
possibly mean? --Tamfang (talk) 06:40, 26 June 2024 (UTC)
- I won't look closely at the article until later, but the natural meaning would be the distance between the center and the closest and most distant points on the curve. "Semimajor and semiminor axis" are terms which have a unique defvinition for an ellipse, but would not for a squircle. AnonMoos (talk) 07:29, 26 June 2024 (UTC)
Periodic squircle
[edit]It would be nice to have at least one illustration. AnonMoos (talk) 19:20, 19 October 2024 (UTC)
- I plugged it into https://www.desmos.com/calculator - it looks like the other illustrations, although the squircle is repeated periodically in diagnoal directions. ~Anachronist (talk) 22:47, 22 October 2024 (UTC)
Can this be generalized to any polygon?
[edit]I'm wondering why this shape is restricted to a square. For the periodic form, could it be generalized to some other period to make, say, a triangle (triancle?). I'm playing with it in Desmos and haven't been successful. ~Anachronist (talk) 22:49, 22 October 2024 (UTC)
- I believe the shape having the word square influencing the name might be why. You’d have to rename other shapes, like trircle. 50.39.254.254 (talk) 14:59, 10 April 2025 (UTC)
Wanting to translate but need help
[edit]I want to translate this article to portuguese since I'm brazillian bit i can't find the way to translate it, i know how to edit but not to translate IsaqueCar (talk) 22:29, 18 November 2024 (UTC)
- There are currently versions of this article in ten different languages, but unfortunately Portuguese isn't one of them. If you would like to help produce a Portuguese version, see Wikipedia:Translate us for step-by-step instructions. Modest Genius talk 13:30, 19 November 2024 (UTC)
- I want to contribute but i cant currently because i need to edit more articles because of the new rule wikipedia added IsaqueCar (talk) 18:04, 20 November 2024 (UTC)
Statement about apple icons not supported by reference
[edit]The text claims that apple icons are quintic superellipses and cites [12] which states actually that apple icons are NOT quintic superellipses...with an overlay showing how they disagree! 192.80.55.86 (talk) 14:46, 6 December 2024 (UTC)
Linearization formula for FG
[edit]The formula to change s_L to s with s in [O,1] is wrong. I tested it. In order not to get a negative radicand, you must choose an s >= 3.414, obviously not in the range. I fixed it and an arrogant quack changed it back. If you want to put BS up here for everyone to see, be my guest. For those truly interested, look at the source and do the math yourself. I’m a mathematician by trade, so what do I know, right? ~2026-55254-6 (talk) 01:44, 26 January 2026 (UTC)
- Log in before you post. The account who made that change is not the same as the account who wrote the comment above.
- I've tested it too, and it did what I expected, move the corner of the squircle to the expected position between the circle and the square. We don't misrepresent what cited sources say. If you want to say something else, then find a source that says it. ~Anachronist (who / me) (talk) 15:47, 26 January 2026 (UTC)
- Aha, I see now. I had tested the formula in the cited paper, but the formula in the article has a typo. The paper had the term (2-2sqrt(2)) in the numerator and this article had (2-sqrt(2)). I changed it to 2(1-sqrt(2)).
- Now the formula in the article matches the cited source.
- Your change also drastically modified the denominator, and that was the basis of my reversion of your change. I hadn't noticed the typo in the numerator with the missing 2. ~Anachronist (who / me) (talk) 16:10, 26 January 2026 (UTC)
- Oh my, this is embarrassing. That was my typo. I added that section on linearizing squareness in this edit in 2024, and I mis-transcribed the formula from the cited source. ~Anachronist (who / me) (talk) 16:40, 26 January 2026 (UTC)
