이며, S는

이다. 여기서, Smax는 최대 변형 값이고, Kstr는 늘어남의 비율이다. 상기와 같은 두 수학식을 통하여, 늘어남이 없을 때 S=1이고, 속도가 무한대를 향해 증가하는 경우에 S=Smax임을 알 수 있다. 모션 블러(motion blur)는 움직임이 더 부드럽게 나타나도록 하는데 유용하며, 거칠거나 노이즈가 있는 움직임을 개선한다. 이와 같은 모션 블러는, 컷아웃의 경로를 따라 컷아웃의 다수의 복사본을 만들어서 렌더링(rendering)하여 점차 사라지도록 구현될 수 있다. 그림자(shadow)는 컷아웃 전체에 의해 드리우는 '컷아웃 그림자(cutout shadow)' 또는, 컷아웃 상의 그림이나 텍스트에 의해 드리우는 '선 그림자(line shadow)'일 수 있다. 반복(repetition)은 반복적인 움직임을 나타내기 위한 것으로서, 반복되는 움직임에 간격을 지정할 수도 있다.Fade-in, fade-out, ease-in, and ease-out are useful for indicating smooth motion, and fade-in and fade-out the basic period of the fade-out may be 0.5 [sec], and the basic period of ease-in and ease-out may be 1 [sec]. The squash and stretch is controlled by the scaling factor S along the principal axis. The two-dimensional scaling matrix

And S is

to be. Here, Smax is the maximum deformation value, and Kstr is the rate of increase. Through the above two equations, it can be seen that S = 1 when there is no increase and S = Smax when the velocity increases toward infinity. Motion blur is useful for making motion appear smoother and improves rough or noisy motion. Such a motion blur may be implemented so that multiple copies of the cutout are made along the path of the cutout and rendered to disappear gradually. A shadow can be a 'cutout shadow' applied by the entire cutout, or a 'line shadow' applied by a picture or text on the cutout. Repetition is intended to indicate repetitive movements, and it is also possible to specify intervals for repeated movements.

FIG. 10 shows an example of an animation result obtained by applying information on the additional motion of the cutout.

The animation implementing unit 104 implements an animation according to the output of the generating module 103.
