CNet reports on the technology behind Pixar’s Up. Not any diferent from their past films you might say? “Try thinking of the algorithms required to animate more than 10,000 helium balloons, each with its own string, but each also interdependent on the rest, which are collectively hoisting aloft a small house… Consider that within the cluster, every interaction between two balloons has a ripple effect: If one bumped another, the second would move, likely bumping a third, and so on”. The article looks back on challenges Pixar faced in previous films as well as how they got past the one in this film.
