How do I draw a pair of buttocks? (2014)
- synu 4y agoWow, great detailing on the cleftal horizon. It's interesting to see this expressed mathematically in this way.
- frozenlettuce 4y agoCould you, Sir, write a mathematical formula pointing where the defendant kissed you?
- benj111 4y ago> cleftal horizon I was going to complement you on making up a term, but I googled and it is unfair a thing.
- jabbany 4y agoI think this is an IT Crowd reference ;-)

- metayrnc 4y agoFor anyone interested in drawing/sculpting with math, I would highly recommend this channel. There are some amazing things. https://youtube.com/@InigoQuilez https://youtube.com/@InigoQuilez
- pdpi 4y agoWas about to link the exact same thing. For context, Inigo is one of the authors of Shadertoy.
- joenot443 4y agoIQ is the man! He’s the dev behind ShaderToy. He’s seen as somewhat of a Gandalf figure in the amateur shader dev community; some of what he produces in GLSL is light years beyond what most devs can conceptualize in a shader.
- jstrieb 4y agoI second this recommendation, Inigo Quilez is amazing! If you're interested in learning the fundamentals of some of the math he uses, I can highly recommend the CMU computer graphics course. It's free on YouTube. https://youtube.com/playlist?list=PL9_jI1bdZmz2emSh0UQ5iOdT2xRHFHL7E https://youtube.com/playlist?list=PL9_jI1bdZmz2emSh0UQ5iOdT2... The professor, Keenan Crane, puts out a ton of super interesting, high-quality research as well. His website is awesome. https://www.cs.cmu.edu/~kmcrane/ https://www.cs.cmu.edu/~kmcrane/
- beiller 4y agohttps://youtube.com/@TheArtofCodeIsCool https://youtube.com/@TheArtofCodeIsCool has been my favourite so far, and he focuses on writing shaders. This seems like the next logical step thank you for sharing!
- idrios 4y agoSo glad someone else posted this, his shader tutorials are so good!
- junon 4y agoHe's pretty much the GOAT of SDF art, and as such he created https://shadertoy.com https://shadertoy.com if you're interested in that kind of stuff.

- KirillPanov 4y agoGotta love the triple-cheeked butt (tutt? 3-butt?) in the last example.
- DonHopkins 4y agoZaphod Beeblebutt
- JackFr 4y agoOnce you solve the n-butt, classical butt is just a special case.

- kennyadam 4y agoPlease keep these pointless pun threads on Reddit. HN doesn't need this taking over here too.
- ectopod 4y agoYou don't have to read every story on HN. Maybe in future you could avoid any obviously unserious ones. The word "buttocks" in the title is a good hint of what to expect.
- kcplate 4y agoAhh yes the obligatory “we must never use humor here on HN” comment has arrived.
- inanutshellus 4y agoIn defense of the curmudgeon, the mature atmosphere of HN is quite rare and, frankly, refreshing.

- nixass 4y ago(. )( .) There, I fixed it for ya
- irrational 4y agoI never realized that female nipples point at a 45 degree angle from each other (i.e., they do not point straight ahead) until I took a human anatomy drawing class. It was interesting that something right in front of me was not obvious until pointed out.
- Hamuko 4y agoIs that angle dependent on breast size?
- b112 4y agoCareful now, too much discussion on this point, and you'll invent a new compression algo.
- Mezzie 4y agoThere's a correlation but it's not a dependency. A woman with very small breasts won't have the tissue volume to have nipples pointing at certain angles, but in average to large sized breasts, they point in many different angles. It's more dependent on tissue density + how self supportive the breasts are. I'm a bra fitter. I look at a lot of boobs.
- MerelyMortal 4y agoDoes that make it easier for breastfeeding?
- rizky05 4y ago( .)(. ) We shall animate it
- eCa 4y agoCl***ic.
- wffurr 4y agoClbuttic
- MerelyMortal 4y agoClbottomic
- cunningfatalist 4y agoThis is way more amusing than it should be.
- civilized 4y agoThe top answer is really imprassive.
- louthy 4y agoI just had to check that 'imprassive' wasn't a synonym for buttocks!
- hoseja 4y ago[flagged]
- Symbiote 4y agoIt seems a fairly normal Spanish-speaker-speaking-English accent. I have no problem with it. Expect people to take offence if you complain about their accent — potentially very serious offence, as English accents and race or national identity are strongly linked in many places.
- 4gotunameagain 4y agoNon native speakers usually "tolerate" and understand a more wide range of accents, if they learned english in a multicultural environment where everyone had a different accent. Also in general between both native and non native speakers, commenting negatively about someone's accent is considered rude, or colloquially, an "asshole move" If you are a non-native speaker without encountering such accents you must be Indian, right ?
- maeil 4y agoThis does not match my personal experience; having lived in countries on both sides of the equation, with those in the more non-native country (South Korea) having a much less tolerant for non-American/British accents (e.g. Chinese, Indian, Filipino) than those from native or very high-fluency countries. I.e. Ive found tolerance for non-native accents to be inversely correlated with personal fluency.

- 4gotunameagain 4y agoI had in mind environments like Europe, where social interactions are like the beginning of a joke: A Czech, a Dutch, a Greek and a French walk into a bar..
- fho 4y ago
- MikeDelta 4y agoFunny how it triggers all sorts of puns in the replies: "This might get me suspended from the site butt I cannot resist."
- qwertox 4y agoAs long as it stays an exception to the rule. I would not want to see HN turn into Reddit.
- notRobot 4y agoQuote in parent comment is from OP's answers, not this HN thread.
- Kaibeezy 4y agoYou’re right, humor almost always gets flushed hereaboots. Fascinating how the fury let loose on this one. Must have been quite a bit of pressure backed up, now thankfully relieved.
- jdmichal 4y agoI've seen plenty of tasteful and smart joke threads on here. What's not tolerated are low-effort and meme jokes.
- kcplate 4y agoThat comment was brilliantly constructed.
- layer8 4y agoThe Poasson distribution is what got me. In German, this is actually a double pun, because Po = butt.
- elproxy 4y agoI assumed it was going for psoas, but popoasson would work too...
- ur-whale 4y agoStrikes me as the perfect target for a truncated 3D Fourier transform.
- tazoptica 4y ago1. Use Mathematica. 2. Draw the rest of the butt.

- tunnuz 4y agoArse technica.
- kennyadam 4y agoPlease don't stink up this place with pointless puns, keep it on Reddit.
- moffkalast 4y agoOh don't be an ass.
- cafeinux 4y agoYour choice of the word "stink up" makes the whole thing more funny. Maybe it was intended, but(t) I'm a very literal person.
- tunnuz 4y agoYou’re right of course. I apologize, and promptly turn the other cheek.
- layer8 4y agoThey’re not pointlass, they are pretty much on point.

- plebianRube 4y agoWhat better answer than drawing butts of course, to all of those students who are wondering where they would ever use sin/cos/tan in a real world application.
- bentobean 4y agoWhat a great way to draw in students and encourage them to engage with the material. “25 extra credit points to the first student who submits an algorithm for drawing a butt.”

- radec 4y agoTIL? a pair of buttocks is just one butt? So a buttocks is just one cheek? I had no idea.
- XCSme 4y agoWouldn't it be a buttock?
- JasonFruit 4y agoYes, it is, in fact, a buttock.
- radec 4y agoPair of buttock? You mean or still pair of buttocks?
- planede 4y agoIt's generally "pair of <plural>".
- radec 4y agoOk, thank you. I guess that makes sense.
- JasonFruit 4y agoOne is a buttock. Two is a pair of buttocks. Three or more is linguistically possible but physically unlikely.

- _a_a_a_ 4y agoMost interestingly, I can't see the top answer (by mikuszefski) as anything mathematical, it just looks like body parts. Quite odd.
- hallomisky 4y ago1. Draw some circles 2. Draw the rest of the fucking buttocks
- hallomisky 4y agoBased on this meme, in case I get downvoted for swearing: https://knowyourmeme.com/memes/how-to-draw-an-owl https://knowyourmeme.com/memes/how-to-draw-an-owl
- plusminusplus 4y agoWe know it's based on the meme. You're probably downvoted because it's played out and doesn't really apply to this specific post much. It would perform well on reddit surely.
- hallomisky 4y agoHm, I didn't get downvoted as far as I saw, but thanks for the clarification. I will be sure to follow your strictures to the letter in the future :-*
