由3D扫描技术衍生的计算机3D动画之Ⅱ——动画驱动技术

3D Computerized Animation Derived from3D Scanning Technology-Ⅱ.Animation Drive Technique

3D动画序列的生成,是一项复杂的工作。本文详细介绍了动画驱动中涉及到的角色动力学模型、运动控制、运动编辑和色造型等技术。阐述了关节动画主要算法的优、缺点;运动编辑过程的重要意义,以及运动重定向、运动变形和运动变换等环节并且对现行的角色造型模型进行了比较。最后介绍了动画驱动的工具及应用的发展和现状。

Making3D animation series is a very sophisticated work.This paper outlines in detail main problems relevant to animation drive technique,e.g.role model dynamics,motion control ,motion editing,role mod-elling,and also advantages and disadvantages of human body joints animation calculation methods,importance of motion editing process,motion reorien tation,distortion and modification etc..Different models for building roles are compared;finally,the present status and development of animation tools and applications are dis-cussed.
