Animation is the production of consecutive images,which,when displayed,convey a feeling of motion.Animated images are almost magical in their ability to capture our imagination.By telling a compelling story,astounding with special effects,or mesmerizing with abstract motion,animation can infuse a sequence of inert images with the illusion of motion and life.Creating this illusion,either by hand or with the assistance of computer software,is not easy.Each individual image,or frame,in the animated sequence must blend seamlessly with the other images to create smooth and continuous motion that flows through time.
Traditionally,animation was created by drawing images of the characters for each frame in the action.At the start of the production,the animator is given storyboards,which are sketches depicting the sequence of major actions and illustrating the expressions of the characters.The animator also works from a finished soundtrack,which determines the timing of the piece.In older animations,the background scenery was often stationary and the characters were painted on cels,pieces of clear celluloid that could be stacked on top of the background.Most hand animation is created with keyframing where a lead animator creates the key,or most important frames,and a second animator creates the in between frames.Regardless of the medium,the challenge for the animator is to create images that impart expressiveness and life to the character.
The most basic computer animation tools assist the process of traditional animation by automatically generating some of the frames of animation.Animation tools have also been developed to composite together multiple layers of a scene in much the same way that layers of cels are used in hand animation.Other more powerful techniques make use of algorithms that render an image from a geometric description of the scene.These techniques change the task from drawing sequences of images to using computer tools to effectively specify how images should change over time.

动画制作,意即绘制播放时产生出动感的一连串图像.逼真的图像近乎神奇地俘获着我们的想象力.凭借着引人入胜的故事讲述,眼花缭乱的特技效果,或者抽象化的运动设计,动画制作为一连串毫无生气的图像注入了动感和生机.不管是使用手绘还是借助于电脑软件的辅助,要想营造出这样的幻觉都并非易事.动画序列中的每一幅影像,或者叫作“帧”,必须与其它影像契合得天衣无缝,才能制作出随着时间推移而不断变化的流畅且连贯的动态效果.通常,动画制作要绘出动态中每一帧里人物角色的形像.在作品的开始部分,动画师会使用情节串连图板,那是用来概述主要情节的来龙去脉,以及图解阐释角色表现的.大多数手绘动画采用的是由首席动画师绘制关键部或多数重要的帧,再由第二动画师制作连接帧的方案,这叫作“主帧编辑法”.无论采用什么手段,动画师所面临的难题,都是制作赋予角色以表现力和活力的影像.
最基础的电脑动画制作工具软件会自动地生成动画的一些帧以辅助传统的动画制作工序.电脑动画制作工具软件还已发展出“叠层影像”的合成技术,其原理跟手绘动画制作的单帧多层复合差不多.其它更为强大的技术利用的是能提供几何绘图的场景影像的运算演示.这些技术改变了动画制作依靠手工绘制套图的面貌,高效地运用电脑工具软件摹画出随时间而变化的影像.
