基于行为复合机制的结构化图形动画技术的研究与实践

The Study and Practice about Vector Graphics Animation Based on Compound Behavior

在各类计算机动画中 ,角色动画可满足实时性及交互性的需要 ,其核心技术在于角色的建模技术。该文主要介绍了作者所研制的角色动画制作系统———“网动王 98” (简称Net_Anim系统 )中所采用的角色建模机制及其相关技术 ,内容包括 :角色的对象模型及其运行机制 ;角色复合行为的实现算法及相关的关键问题 ;应用示例 :Net_Anim系统的特色和有待进一步研究和解决的相关问题。

According to the designing methods, computer animations can be divided into three kinds: frame by frame animation, keyframe animation and actor animation. Actor animations may meet the demand for real time and interactivity. The model of actor is the key for actor animation. This paper mainly presents the modeling method of the actor in Net _Anim system developed by the author, which includes: the object oriented model of the actor and the control scheme based on the model; the algorithms for synthesizing compound behaviors and some key problems to be considered; an example to demonstrate the compound actor with compound behaviors; the characteristics of Net _Anim and some problems to be solved in the future.
