1、第14章 三维动画表现 制作卡通动画本章导读：在动画电影领域，三维动画凭借着真实的效果和更高的工作效率已经逐渐取代了传统的手绘动画。3ds Max的开发目的就是为了制作三维动画。在本例中我们就利用3ds Max强大的动画制作功能制作一段具有动感的动画短片。1Evaluation only.Evaluation only.

4、光、摄影机等照明和构图工具都可以被称为对象。在创建对象的过程中需要完成创建各种模型，为模型编辑材质和贴图，进行环境与重点照明等工作。3Evaluation only.Evaluation only.

5、成有了对象后就需要为对象创建各种动作。不但包括角色的动作、物体的空间运动，还包括颜色、透明度、形状、大小等属性的变化，速度与节奏感的变化，以及光效、大气效果、粒子效果等特效。合成阶段主要通过视频编辑软件完成，在视频编辑软件中需要将完成动画的各片段进行连接、排序、剪辑等后期处理。然后为动画配音、并且制作各种音效。4Evaluation only.Evaluation only.
