FINDING DORY – AND DRAWING HER
Soon the movie Finding Dory comes out, as the follow-up to Finding Nemo. Once again we get to watch funny fish search the big ocean for family. These movies don’t show real fish, though. They’re “animated,” meaning the movie shows lots and lots of drawings, called frames. Each frame is just a little different from the one before: maybe the fish moves over a tiny bit, or a turtle lifts his head. When you flick through 24 or 30 drawings every second, the characters look like they’re moving! So our friend Callie S. asked, how many people does it take to make a movie like that? Turns out Toy Story needed 27 animators to make the 77-minute film, and 800,000 hours of computer time. Movies since then have used even more — after all, Sulley from Monsters, Inc. has 2,320,413 hairs. But don’t worry, animators use math to make all those hairs move! If you work hard at math, maybe you can grow up to do this super-cool job, too.
Wee ones: If it takes 5 pictures to show Nemo flicking his fin, what numbers do you say to count them?
Little kids: The octopus in Monsters, Inc. has only 6 legs, as a joke. How many more legs should it have?
Big kids: If 20 animators each drew 3 minutes of film, would that be enough for 77 minutes? Bonus:If you need 30 frames (pictures) each second, how many do you make for 1 minute of movie? (Hint if needed: What would 3 frames per second for 6 seconds be? Then, 30 frames for 6 seconds…then how about 30 frames for 60 seconds?)
The sky’s the limit: If 50 computers run all week except for an 8-hour break, how many weeks would it take for them to run a whole 800,000 hours of work in total?
Answers:
Wee ones: 1, 2, 3, 4, 5.
Little kids: 2 more legs.
Big kids: Not quite! They’d make 60 minutes. Bonus: 1,800 frames just for 1 minute.
The sky’s the limit: 100 weeks. First, a week has 24 x 7 or 168 hours. If the computers take off 8 hours, that’s 160 hours for each. So 50 computers together can do 8,000 hours of work. It would take them 100 weeks, or almost 2 years (if the article’s right that it really took 800,000 hours)!
