Computational techniques improved considerably the animation production. Traditional animation is more time consuming and is also an intensive labour method. One recent example is the movie Loving Vincent, that required more than a hundred painters to create the animated movie. The process thanks to computer technologies is more efficient and cost less to produce. Besides that, the results achieved with the 3D animation production are not possible to achieve in traditional animation. If one considers the perspective of each frame, it has a huge impact on the storytelling and in the viewer experience. Changes in perspective and the point of view of the frames have a bigger impact in traditional animation while in it can be easily changed in 3D projects.
Considering this, computational technologies increased the margin of error in the production process, because a number of steps can be undone.For example, one kind of computer animation is the scripted animation, that is based on frames and interpolation. In the traditional animation, the illusion of movement was created through the illustration frame-by-frame, with an illustrator creating the key-frames frames and a team of animators working in the in-between frames. Computer animation, on the other hand, the key-frames are set and the in-between animation frames are generated automatically by the system through interpolation. One technique to animate the in-between frames is the linear interpolation (Fig. 13), that allows calculating new positions at equal intervals along a straight line (Spalter, 1999). You determine the number of positions calculated and thus the number of frames created. There is also the nonlinear interpolation (Fig.
14), that creates a more realistic motion effect. In the case of frames and in-between frames, the computational techniques reduced the time and also the production costs, because the computer substituted a number of people that would be involved in the process of drawing the frames. At the same time, the accuracy in terms of the ‘pencil strokes’ of the draw are becoming standardized, what would be hard to achieve in the hand-drawing process.
For example, by observing the classic Snow White and the Seven Dwarfs from Disney, it can be noticed some little changes in the formats of the animated objects and characters, also the flow of movement is not as realistic as can be achieved with computer technologies.
