Around 1993-1994 it was indeed the birth of raytracing 3d animations.

Grats on getting the rights to this iconic film!!! this bad boy has been floating around the internet for a long, long time and it was always some random upload. i love seeing one of the creators having it on their own channel
I remember finding this video years ago as a high schooler and having to watch it twice to catch the more advanced work towards the end of the video. Now Im out of college and got recommended this while high and I've watched it three times already and I'm just enjoying the pretty sounds
Thanks to this video, I was able to stop a massive home invasion by explaining to them how to turn a sphere outside in. Truly one of the videos of TH-cam.
thanks for the tutorial! i got a sphere made out of a material which can pass through itself and destroys itself if it is punctured or forms a crease a few years ago for christmas, and at some point my little cousin came over and turned it inside out and i hadn't been able to figure out how to turn in back inside in. i think they just swapped the pink and yellow stickers, but i think this is a much more orthodox method of doing it
Thanks for making the Geometry Center playlist! I never knew there was such a treasure trove of other videos like this. I have a lot of watching to do!
I'm convinced that someone made this in Blender, used Ai voice on the commentary and time-traveled back into 1994 to show it. This looks insane even in todays standard.
@@AdolfHitler-lk4vo mesh = set of polygons which connect to form an object. usually used for stuff because they're pretty easy to modify and render. making a mesh work for this would require so much geometry to make it so smooth that it wouldn't be worth it.
I’m in amazement how humans can figure out something like this without computers, but I’m even more amazed at how we create problems like this for ourselves
Math, geometry, and algebra were always a struggle for me. I instead excelled in the linguistic areas. This blew my mind and actually made me comprehend the concept without issue. Where was this when I was going through high school?
I remember watching this in high school in the early 2000's, what a trip to see it again. It blew my mind, while confusing the heck out of me when i first saw it!
I love watching this video, the entire Geometry Center trilogy is awesome!! :D Having seen this so many time I think I finally understand how to turn a sphere inside out lol
I love videos like this because they make me feel dumb and a good distraction from all of life’s problems. A great pass time. Thanks for sharing. I don’t understand it but I think I trust the lot behind it🤔
Yeah same. What practical uses does this have? Especially since there is no object that holds its own Form to be able to be physically manipulated through its own self. One thought that came to mind is that this might have to do with the manipulation of sound perhaps?
@@charliepace107 It might be useful to scientists that are figuring out the nature of reality. Things like electrons and photons aren't really tiny balls of stuff, they're more like waves that move through fields in space just like sound waves that you mention.

@@underlightmusic I'm not talking about Dinosaurs from the Jurassic era, I'm talking about a group of scientists who turned a sphere inside out 50,000 leagues down under and they ended up getting dementia from it. It nearly cost them their lives, luckily they all survived. One of the survivors Raymond Babbitt got autism from it and is now taken care of by his younger brother Charlie Babbitt. There's a movie based on them too, it's called Raining Men, it's also a mind bender.
@@shadowcween7890 na bro i known a guy who got his head right rattled like scrambled and shit from some jinglitok idk wtf it was just some long name shit anyway he had to be in hospital for a bit and when he got out he came out completely different and his wife at the time said this to him so he went to the hospital again and they did some questions and wrote some shit down then went off to some room to cognate, then came back, and talked to him that he they think he got autism now and they did some tests and shit like probed him idk and they concluded that he defly autistic so yea you can get autism.
Weird point, but im so happy that the voice of the mathematician who understands the concept is a feminine one. Girls arent taken seriously and STEM fields, and this was great to see.
One of those things that I don’t get.I understand that girls have made important results in many scientific fields but why consider it in this specific video?
At first I thought I wasn't on enough drugs for this, then I remembered mathematics are meant to be paired with the most mind-bending drug of all: total sobriety.
The amount of guide strips can be determined by the surface area added to the sphere- the sphere, as the video explains, must be "corrugated" (expanded by surface area) to compensate for "pinching" (points of Intersection or edges that appear on a circle that make it not a circle anymore) the amount of corrugations, and guide strips, must be over a quantity relative to the added surface area of the sphere to allow the sphere to twist onto itself.
@@joekinnear4671 "surface area" considerations don't seem plausible since you can expand and contract as much as you want. In fact, the initial 2D example they showed with corrugations doesn't require a single corrugation. You can simply translate the first knot through the second one, after which it is easily undone. No pinching required.
@@Henry-fv3bc secondly, surface area is entirely plausible with an object that can stretch and warp- otherwise, how would we measure balloons and their size? Besides, if you wish to calculate a formula that determines how many guide strips are necessary to invert a sphere under these conditions, you can decide whatever units of measurement you decide you want to use, but realize that surface area will come into play with said hypothetical equation.
@@joekinnear4671 I am talking about the shape displayed at 11:26. Since this has the same turning number as a circle, a continuous transformation to a circle does exist but my point is that corrugations are not required to avoid pinching like shown in the animation. It also sounds like you've misunderstood my point about surface area. I never said these shapes can't have a surface area or perimeter, my point was simply that surface area couldn't be a constraint on the number of guide strips since you can make the strips as large or as small as you'd like or scale the shape or part of it at any point as much as you'd want.

Thanks to this video, I was able to stop a massive home invasion by explaining to them how to turn a sphere outside in. Truly one of the videos of TH-cam.
thanks for the tutorial! i got a sphere made out of a material which can pass through itself and destroys itself if it is punctured or forms a crease a few years ago for christmas, and at some point my little cousin came over and turned it inside out and i hadn't been able to figure out how to turn in back inside in. i think they just swapped the pink and yellow stickers, but i think this is a much more orthodox method of doing it
Lol
Just lol 🤣
your comment is comedic genius
The level of competence in the explanation is very impressive.
The sound design here is so insane. The vibes on these videos is unmatched. Love all of this content.
Did we talk about the fact that this video is appearing in everybody's recomendation without reasons
"You cannot crease it or bend it sharply"
*Proceeds to crease the ball a million times*
How is that creasing?
Those are just parts of the ball clipping through each other, which is different since this is all theoretical
I can't comprehend how complicated this is
Someone skipped through half of the video.
Those weren't creases.
I love the little bass riffs in the background coordinating with the visuals
Thanks for making the Geometry Center playlist! I never knew there was such a treasure trove of other videos like this. I have a lot of watching to do!
I'm convinced that someone made this in Blender, used Ai voice on the commentary and time-traveled back into 1994 to show it.
This looks insane even in todays standard.
Hell nah, this isn't even shit blender could manage, because it's very heavily based around meshes, while using one here would just be too clunky.
@@munsterlandr1644 what?
@@AdolfHitler-lk4vo mesh = set of polygons which connect to form an object. usually used for stuff because they're pretty easy to modify and render.
making a mesh work for this would require so much geometry to make it so smooth that it wouldn't be worth it.
@@munsterlandr1644 thats not true tho
@@AdolfHitler-lk4vono it is, as a blender user and general 3D tech studier i can confirm
I like the surreal vibes of this
I’m in amazement how humans can figure out something like this without computers, but I’m even more amazed at how we create problems like this for ourselves
i really love the sound design in this, the sound cues were surprisingly helpful
no one can have better knowledge in this than the guy who animated this
The animation shows deformation of the sphere using eight ribs. Is there a minimum number of ribs that would be required to achieve the same result?
At most 2, maybe 1. I'. not a mathematician though, just equcatedly guessing.
God took one rib away from Adam to create Eve. We have 24 ribs.
@@A-432-Zonewell done
I love learning practical skills like this.
i'm amazed at how accessible this video makes differential topology. nicely done.
Math, geometry, and algebra were always a struggle for me. I instead excelled in the linguistic areas. This blew my mind and actually made me comprehend the concept without issue. Where was this when I was going through high school?
This kind of stuff is a hell of a lot cooler when you no longer have to explain it in a Math Class.
I remember watching this in high school in the early 2000's, what a trip to see it again. It blew my mind, while confusing the heck out of me when i first saw it!
These videos have been in my reccomended since the dawn of time even though i never click on them
I love watching this video, the entire Geometry Center trilogy is awesome!! :D
Having seen this so many time I think I finally understand how to turn a sphere inside out lol
The fact that this was created in 1994 is insane
I love videos like this because they make me feel dumb and a good distraction from all of life’s problems. A great pass time. Thanks for sharing. I don’t understand it but I think I trust the lot behind it🤔
Everyone is talking about the animation, but this is so genius
This was released the year I was born. I feel honored to be as old as this masterpiece.
@@Andr3G908 30 years ago I believe
Truly one of the most legendary TH-cam videos of all time.
these weird animated science videos for the late 20th century are always a trip
Watched this years ago and have made use of it just about every day. Awesome vid.
Yeah same. What practical uses does this have? Especially since there is no object that holds its own Form to be able to be physically manipulated through its own self. One thought that came to mind is that this might have to do with the manipulation of sound perhaps?
@dave0351we use it to turn onion inside out without creating folds.
@@charliepace107 It might be useful to scientists that are figuring out the nature of reality. Things like electrons and photons aren't really tiny balls of stuff, they're more like waves that move through fields in space just like sound waves that you mention. I don't know, we need to call Brian Cox.
@@myleswillis everything being waves doesn't really have anything to do with this
@dave0351 just turn the football ball inside out to seal the hole and turn it back out. profit!
I admit one thing ... I did only understand like 13% of this, the only reason I kept watchigng till the end was her soft and calm voice... God damn that was relaxing XD
Bu videodan hiç bir yerde ogretilmeyen bildiğim hiç bir yerde kullanılmayan ve ne işe yaradığını anlamadığım şeyler öğrendim teşekkürlerr
This is the amongst the most intriguing video with out of context title I have ever run into. Need to thank the YT gods for this one.
There was a movie based on this, it's called Sphere and it's a mind bender.
Sphere was not based on geometry man, it was a sci-fi movie about aliens...
Lol. That's based on a Michael Crichton novel and not related to this video. Would be fun if it were, though.
@@underlightmusic I'm not talking about Dinosaurs from the Jurassic era, I'm talking about a group of scientists who turned a sphere inside out 50,000 leagues down under and they ended up getting dementia from it. It nearly cost them their lives, luckily they all survived. One of the survivors Raymond Babbitt got autism from it and is now taken care of by his younger brother Charlie Babbitt. There's a movie based on them too, it's called Raining Men, it's also a mind bender.
@@Tony-lf3zt "Got autism from it" What a funny movie. People don't just get autism, they're either born with it or not.
@@shadowcween7890 na bro i known a guy who got his head right rattled like scrambled and shit from some jinglitok idk wtf it was just some long name shit anyway he had to be in hospital for a bit and when he got out he came out completely different and his wife at the time said this to him so he went to the hospital again and they did some questions and wrote some shit down then went off to some room to cognate, then came back, and talked to him that he they think he got autism now and they did some tests and shit like probed him idk and they concluded that he defly autistic so yea you can get autism.
Thank you for uploading your an absolute legend 🫡
I don’t know if I just got smart watching this or if I got fooled by some weird AI video but what we all agree is important is these edibles work!
No ai here. CGI.
Yeah, too old for ai
@@itz_daniel7144 is this comment written by AI? Don’t try to ex machina me! I don’t care how hot your skin is!
@@itz_daniel7144 people are silly.
I’ve started reading all of my data science readings and such in the way they speak in this video and it honestly helps so much
this video has been showing up in my recommended for YEARS it just doesn't stop, please I've already seen it just leave me alone
The "huggbees" version of this is just 💀💀💀💀💀💀💀💀💀💀💀
"I GOT YOU NOW YOU DUMB BITCH"
the huggbees version is all i think about when i see this
@@uhhhhhhhhhhhhhhhhhhhhhhhhh0it still makes me uncomfortable to this day
This feels so funky I’m 100% interested and paying attention it’s 3 :56 in the damn morning
Seis da manhã e isso está em inglês
Weird point, but im so happy that the voice of the mathematician who understands the concept is a feminine one. Girls arent taken seriously and STEM fields, and this was great to see.
that is such a silly thing to consider important
Tf
Elizabeth Holmes was taken seriously and look how that turned out lol
@@tomorrowilearned8471 Women getting into STEM fields shouldn't be disregarded because of one dumb person.
One of those things that I don’t get.I understand that girls have made important results in many scientific fields but why consider it in this specific video?
The woman’s narration is so soothing, she has such a lovely voice
At first I thought I wasn't on enough drugs for this, then I remembered mathematics are meant to be paired with the most mind-bending drug of all: total sobriety.
This video right here is about to help solve the tangles in my headphone cord 🎧
YES AND ONLY
The most unbelievable thing about this is that i actually understanded something
I understood that
absolutely incredible! i didn’t think i needed to watch this video, but i’m glad i did!
The time of the year has come where youtube reccomends me again and i watch it... see you guys next year!
You back yet?
I haven’t recovered from hugbees version that I genuinely thought was the original.
Had this video recommended for years but never bothered to get past the intro and watch the whole 20 min thing, this was pretty cool!
Wow, this is so interesting, I can feel my mind folding outside in.
Dude I feel asleep with autoplay running and woke up to this playing lmao
HAHA
I bet what your dreaming would be crazy.
These random videos always find me when I can’t sleep, yesterday I was watching a man pour metal in a ant colony.
I’ve seen this before but I can’t remember where or when.
TikTok :)
I've seen this before, and I've also seen the spoof version, but there's something about watching this while high that's captivating!
WATCHING THIS AND THE BETTER ONE BACK TO BACK AND I AM BAFFLED
Omg I saw the hugbees video before this I’m permanently traumatized
Ah yes! The time of the year, this is on my recommendations again.
Thanks for rolling in the VCR playing during class. always the best days🤣
What determines how many guide strips are needed? What's the fewest amount that would enable turning a sphere inside out?
The amount of guide strips can be determined by the surface area added to the sphere- the sphere, as the video explains, must be "corrugated" (expanded by surface area) to compensate for "pinching" (points of Intersection or edges that appear on a circle that make it not a circle anymore) the amount of corrugations, and guide strips, must be over a quantity relative to the added surface area of the sphere to allow the sphere to twist onto itself.
@@joekinnear4671 "surface area" considerations don't seem plausible since you can expand and contract as much as you want. In fact, the initial 2D example they showed with corrugations doesn't require a single corrugation. You can simply translate the first knot through the second one, after which it is easily undone. No pinching required.
@@Henry-fv3bc the entire point of the circle is that It could not be inverted given the circumstances. What are you talking about?
@@Henry-fv3bc secondly, surface area is entirely plausible with an object that can stretch and warp- otherwise, how would we measure balloons and their size? Besides, if you wish to calculate a formula that determines how many guide strips are necessary to invert a sphere under these conditions, you can decide whatever units of measurement you decide you want to use, but realize that surface area will come into play with said hypothetical equation.
@@joekinnear4671 I am talking about the shape displayed at 11:26. Since this has the same turning number as a circle, a continuous transformation to a circle does exist but my point is that corrugations are not required to avoid pinching like shown in the animation.
It also sounds like you've misunderstood my point about surface area. I never said these shapes can't have a surface area or perimeter, my point was simply that surface area couldn't be a constraint on the number of guide strips since you can make the strips as large or as small as you'd like or scale the shape or part of it at any point as much as you'd want.
"that's an interesting idea.... So it's against the rules."
