Wow! the 1997 video Geri's game was the first to use subdivision & midpoints, and it's plain to see how this simple mathematical technique really made animated film so much better! and that is one good short movie!
I like how he said it straight that if you're not liking this the door's right there. Every math lover just thinks that everyone SHOULD find math as interesting as them. Cool guy and I really dig his easy explanations of things.
as much as i respect 3D animation, i really wish hand drawn 2D animation was still common today. The only 2D animation today is Adventure time or Regualr show, what has happened to the art style??!!
I LOVE MIYAZAKI AND STUDIO GHIBLI. Anime is the only type of animation art style I am able to enjoy nowadays. The Japanese invest such talent into their detailed characters and backgrounds. Once again, I am not bashing on Americans! Why can't we simply improve something that was once so innovative and beautiful while creating diverse methods of animation.
I personally prefer the more digital look of 2D Cartoons today. Making the cartoons that you see on Nick and Cartoon Network take just as much talent as they did before but require so much less work. The first thing I think of when I think of cartoons is Code Name: Kids Next Door(No idea why). That was an amazing show. The art style was great and the animation was awesome. I mostly stick to anime these days but 3D animation is something that I have a great love for. The hours and hours of carefully Modeling, Lighting, Texturing, Animating etc. is insane with this stuff. And while all of that is amazing, the part that's the most overwhelming to me is the easiest part, the time it takes to render all this. It likely took weeks or even months. It just amazes me that stuff like this is being created which is why I love Pixar in particular so much.

"Math" would be cool if it wasnt responsible for holding me back for 3 college semesters due to my highschool obsolete teaching methods. Also, never even seen those equations in middle school. Math is pretty much holds back talented people who are good at one thing, but cant advance though his/ her major due to that one math course that he/ she will never utilize in the future.
I loved taking CAD and Geometry the same year in high school, and I loved ceramics years later. Funny because I asked the Ceramics teacher at which point do these two seemingly diverse professions meet. He said no at first, but then realized and replied that there is a special kind of clay people use in movies called polymer clay and that they take a laser and scan the hand-crafted object. There is a time to craft an object using keyboard and mouse, and a time to craft an object with your fingers and wrists. Somehow, I feel as if the more organic designs such as an animal or a tree are better designed with fingers and wrists before being scanned with a laser while the more mechanical designs such as a car or a weapon are better designed with keyboard and mouse and can be printed on a 3D printer.
Math we use all the time, every day, with preprogrammed commands in software we had someone else code and thus are doing absolutely no math, we are just using it.
If your on the cutting edge like PIXAR, ILM, and certain video game studios are, then you don't have prepackaged software to do the innovative things you want done. Thus math is necessary for designing new techniques which will then be streamlined through software.
Do you work in animation or character design? Because that process is not done by the animators, its done most often by a specilist design team, worked out by programmers, and then demonstrated in it's use to the animators.
He said you should've have learned this in the 8th or 9th grade (trigonometry) well my school system must be lacking like hell most students don't get the opportunity to take it here till their senior year.
It's a common story in a lot of places - sadly it's true. You should get your first taste of trig before high school, and end high school with integral calc
As an 3D artist myself i was actually looking forward to the mathametics of poly's / subdivision literations = RAM % = Render times and stuff. This was kind of a let down. Also, is this TED-Ed kids or? (Because i think i heard kids screaming ''woody''...)
First thing Idk why anyone has to dislike this video its like he showing what he does for a living with mathematics. Umm but I swear if he never said anything about math mannnn... I wouldn't of thought it was useless ... thanks pixar best thing ever I would love to make characters with these people one day if I learn it enough.
I wish I had this kind of information when I was in school so I could relate all those abstract ugly graphs and equations with something "real". Kids these days are so lucky and I bet most of them don't realize it.
this is a similar concept to integration I mean the mid point idea, as the number of points increase the curve becomes more legitimate, meaning it's the limit to infinity.
+Eric Morrison I was going to say that he probably compiled this presentation very quickly, but then again he included a whole programmed demo of the subdiv technology, so maybe not.
I don't think of rotation as a use of trigonometric functions, I think of it as a definition. For example, when you look at the standard definition that sin(x) is the length of the side opposite angle x divided by the length of the hypotenuse, it makes sense that asserting the hypotenuse to be equal to one makes the equation much simpler, that is, sin(x) is the length of the opposite side. Such a construction makes the hypotenuse a radius and the length of the opposite side becomes the y coordinate for angle x. The very process of describing the sine function also explains its relation to rotation, thus it is not trigonometry that describes rotation, but rotation that describes trigonometry.
I do 3D modelling and animation and I don't remember doing any math… Especially not trigonometry! If I can suggest something to kids is to learn HTML/Javascript… It is actually used in animation (Javascript) AND web design (HTML & Javascript)!
Scorpionwacom What I meant is that the need to understand basic maths isn't primordial to perform in 3D modelling & animation… What this guy said was mostly a lie. The software and the development of new libraries requires a good understanding of maths. But in general, most of the math is done behind the interface… It is clearly better to first understand logics, algorithms & algebra than understand first the meaningless trigonometry & calculus… Most of the motivation to do math will naturally come when you'll understand WHY you need them… Logically, understanding logics & algorithms is even more important to learn than learning maths… But nobody seems to talks about this. You have to do all the meaningless maths before seeing some basic logics and algorithms.
SymbolX That's only true because somebody who does understand the math has written programs for you (so that you don't have to). Doesn't mean you have no need, it just means you don't care to bother.
***** That's kind of what I said… Most 3D modellers/animators don't understand half the maths I do… And I can definitively say that algebra, logics & algorithms are the essential things to understand… (For your info, I have done my calculus, series, matrix & 3D maths… I studied in Sciences de la Nature (Natural Sciences) in CÉGEP. I do coding, 2D & 3D animation, and many more technical things… *So I bothered to learn theses things!* I simply think it is a lie to pretend you need to understand mathematics to do 3D animations. I never used trigonometry in ANY thing I did on a computer… Or even any practical things in all fields included! It may be practical some weird day, but most people will NEVER need trigonometry…)
Yet you, the animator need to know none of the math required as even full 3d rendering suites are point, click, drag, tweak till fluid. I know, I do 3d artwork :P Sooo yeah feel free to ignore all of that math unless you want to actually make the 3d software.
wow "I think its cool and if you don't the door is there.." No public speaker should say that to an audience... especially with kids.... If they don't give a crap you're doing something wrong.
Now I can tell my students why math is cool. If anyone thinks that all you have to do is puxh a button, your wrong! You have to know if what is showing up after you push that button is correct or not. machines are not perfect. that is why I do not allow calculators in my class (middle school 8th grade.)
OK, SO THEY ARE SUB DIVIDING THAT IS PIXELATING ............ CAN BE UNDERSTOOD AS, WHEN YOU ZOOM TO A IMAGE WITH LESS PIXEL, IT WILL APPEAR LIKE JERRY'S HAND BEFORE SUB DIVIDING THE POINTS WHICH MAKE THE JERRY'S HAND SKIN. BUT WITH MORE SUB DIVISIONS LIKE MORE PIXEL IN A IMAGE IT APPEARS SMOOTH....................
It's not going to be perfect a start in 7 minutes but better math is made scary rather than boring/predictable - scary is what gets the smart and curious more of the time.
I don't know how mathematics actually got in there because in 3D animation, everything is usually automated... Unless of course, these 3D guys code them manually.
He's not really talking about busy-work calculations, he's talking about implementing math in systems which can do the busy-work calculations for us, and developing better math to make the process more efficient.
yes, programmers do the majority of the math here. Artists and designers, not so much. He's making it seem like to be an animator you need to be good at math and you really don't.
To develop that the concept of Subdivide in a software, math was required ! All the electronic gadgets you're using right now is based on math. Everything we know has to have a connection to math ! So yes, we use math ALL the time.
The80sKickAss How could you be so naive ! Take a minute to go through your day and notice how much math you used. When you realize you've been waiting for your friend for over an "hour" or that your spending "50%" of your salary on luxury items is not that much of an "investment" or when you cancel your vacation just because you don't have enough "balance" or when you "calculate" how many hours' work would you have to put in to reach your goal, you USE math. Any kind of accounting and simple calculations, of course, require math. Even if the person is a layman or an Exec, he uses math. You cannot survive without math.
oh, im sorry i didn't realize we were talking about simple addition and subtraction. I was talking about complex math. Also, the ratio of time we spend doing math every day pails in comparison to the amount of time we don't do math. For the majority of people simplistic math is all they will ever need in life. computers do the hard stuff for them.
The animators make such a great job with pixar films.
