Making a Pixar film is not drawing faster with computers. Animators build an entire universe in 3D, then calculate every pixel of every frame — each one taking 1-2 hours of render time on a farm of 117 clustered Sun Microsystems servers. They make a full rough-cut 2D movie in storyboards before touching 3D, because if the story doesn't work in 2D, animation won't save it. The whole process takes 4+ years.
