目前,在动画运动规律设计时,没有对反作用力引起足够的重视,其主要应用的范围有两个方面,第一是角色设计;第二是自然现象。反作用力通过夸张的形式不仅使动画角色在运动时充满张力,还能将自然现象的变化表现得更加具体,将丰富的内涵通过动作加以呈现,可以使动画中形象特征更加鲜明,使整个剧情更具感染力。本文将反作用力对运动设计的作用进行了简要分析,并对反作用力现象的应用进行探讨。 At present, there is not enough attention paid to the reaction force in the design of the law of motion of animations. The scope of its main application is twofold. The first is the design of the characters. The second is the natural phenomenon. In the exaggerated form, the reaction force not only makes the animation character full of tension during the movement, but also changes the natural phenomenon to be more specific, presenting the rich connotation through the action, which can make the image feature more vivid and make the entire story more Infectious. In this paper, the role of reaction force in the design of motion is analyzed briefly, and the application of reaction force phenomenon is discussed.
