This video uses an impressive computer simulation to show what 31 million balloons would look like in real life. The CGI balloons are shown riding the currents of the wind like a floating, rainbow sea.
Blowing up all those balloons would be impractical for an entire team of people, not to mention one elderly man living alone. After watching the video, check out these facts about your favorite Pixar films. In order to carry out this simulation, Pixar tested new shading techniques that would be carried out by its RenderMan rendering software. Managing the complexity of the balloon deck required some new techniques.
The solution was a physics-based simulation. Alexis Madrigal at Wired figured that the house weighed , pounds and would require , spherical balloons three feet in diameter. Nina Rastogi from Slate calculated that if using party balloons 11 inches in diameter with 26 inches of ribbon and accounting for the weight of the balloons and ribbon, you would need over 9. Over at IMDB , someone posted that it would take 12,, balloons to lift a ,pound house.
Pete Docter , co-director of Up , said that Pixar technicians estimated it would take around For the record, Pixar animators used 20, balloons in the scene where the house first took off and 10, balloons in other scenes- not nearly enough based on the variety of the above calculations. During the married life montage movie, Carl shows off his balloon cart to Ellie.
The cart starts to float away, and he jumps to bring it back down. Based on the idea that one balloon could life about 0. Finally, near the end of the movie, Russell uses a cluster of balloons with a leaf-blower to help steer to float to the airship to rescue Kevin. Russell is six, and the average six-year-old is around 50 pounds. If one balloon could life about 0.
I guess we should just assume that the helium in Pixar movies has much more lifting power than our own helium. Featured Image Credit. You are commenting using your WordPress.
A technical director advised that the house requires 23 million balloons based on calculations such as the size and mass of the house, and the size of each balloon. However, Director Pete Docter realized that it would be impossible to have that huge number on the screen, as they would look like small dots.
At the moment Carl releases the balloons from the chimney, the house starts to fly; assuming that all the balloons have been inflated throughout the night and stored inside the house. In the lift-off scenes, 20, balloons appear; in the flying house shots 10, balloons appear, and there are a varying number in other scenes.
Inspired by the movie, a team from National Geographic thought how hard it can be to execute this far-fetched idea.
