动画剧本描述语言SDL／A的设计与实现

THE DESIGN AND IMPLEMENTATION OF ANIMATION SCRIPT DESCRIPTION LANGUAGE SDL/A

本文介绍了基于时序逻辑的动画描述模型和基于此模型设计的动画剧本描述语言ＳＤＬ／Ａ．这种语言具有便于动画设计各个层次的描述、能够描述设计的逐步求精过程、能描述动画中的各种抽象对象以及角色间动作的同步等特点，并易于将这种基本的通用的剧本描述语言集成到一个功能强大的ＣＡＳＥ环境－ＸＹＺ系统之中．

his paper introduces TLAD(temporal logic based animation description)model and an animation description language SDL/A based on this model. SDL/A haspowerful description functions, and is convenient to express hierarchy abstract specification and the step -wise refinement procedure of designing an animation. This language can be used to describe multiactor action concurrency. It is easy to be integrated into a powerful CASE environment-XYZ system. This paper mainly introduces the design philosophy and the implementation techniques of SDL/A.
