Abstract: Skeleton of digital character is one of the most important parts in 3D animation. This paper presents a method on automatic generation of character skeleton with flexible structure. After obtaining position information of skeleton joints through motion capture system, it can build a tree-shaped description of skeleton based on the corresponding XML file. By changing the XML file, it can acquire different kinds of flexible skeletons which could meet the special needs of real Cartoons.

Key words: skeleton, character animation, XML, recursion algorithm

摘要： 数字角色骨骼是三维动画制作过程中不可或缺的关键要素。该文提出了一种结构灵活的数字角色骨骼自动生成方法，它从三维动作捕捉系统获取骨骼关节点的位置信息，根据XML文件信息生成树形骨骼描述。该方法通过修改树形骨骼描述，灵活地生成各种特殊结构的数字角色骨骼，满足动画片对特殊数字角色的需求。
