【摘要】 将全过程计算机辅助动画自动生成技术应用于中国古建领域,实现了一个自动古建动画系统.它根据用户对古建的描述,自动生成三维动画来表现古建的搭建过程,整个自动过程都是在古建知识库的支持下完成的,采用语义网络技术设计并实现了知识库,包括本体库和规则库2部分.主要论述古建知识库的结构、本体和规则库的组成,并以生成古建搭建顺序为例来说明规则推理的过程,共实现了2个方案,一个基于本体构造环境Protégé,另一个基于规则推理系统Jess,后者比前者在推理时间上节省了99%以上,重点论述了高效方案的设计思想和实现技术,并分析了其优点和不足.更多还原

【Abstract】 In applying the full life-cycle automatic animation technology,an automatic animation system was designed and implemented for traditional Chinese architecture.Based on the user’s description of a traditional building,the system generated an animation demonstrating the construction of the building.The whole automation was supported by a domain knowledge base.Semantic web technology was used to implement the knowledge base,including ontological knowledge and rules.The structure and components of the ontology and rule base were presented.Moreover,the inference process through using rules to reason about the construction sequence of wooden components was illustrated.Two implementations were given: Protégé-based and Jess-based.The latter saved up to 99% more of the reasoning time than the former.The details of the Jess-based knowledge base were presented,and its merits and drawbacks were analyzed.更多还原
