摘要： 为使用户可以在一个场景中观察某个对象的多个动画，基于统一建模语言技术并采用“整体-局部”方法，给出三维建模系统动画实现过程与所需模块。以关键帧管理为主线，结合面向对象设计方法，给出实现细节的用例分析。对关键帧采用双结点十字链表结构，提供多方案动画调试功能。根据局部功能给出实现类的设计，为进一步代码实现提供依据。

Abstract: To allow the user watching several animations of the same object in one scene, this paper introduces the basic module and process of animation implemented by 3D modeling system based on UML and through “entirety-part” method. With the combination of object-oriented design method and the management of key frames as the main line, it analyzes detailedly practical cases. It provides multi-functional debugging of animation with a double-node cross list structure in the organization of key frame. A basis for further code realization is provided through the drawing of realized partial function.

Key words: animation, UML, key frame, double-node CrossList
