摘要
针对目前大多数造型系统都是面向单用户环境开发,且造型过程依赖于特征的创建历程,提出以基于细胞元的语义特征造型系统为基础,采用B/S和C/S相结合的方式构造协同框架,进行协同造型的方法。介绍了系统的逻辑设计及网络实现方法。系统可为多用户提供在互联网上同时编辑同一个特征模型的协同设计环境,设计人员可根据特征依赖图(FDG)得到所需的视图,由于网络传输的是造型操作命令,而不是完整的图像信息,因此网络负荷较小,响应速度快。
Most feature modeling systems are all developed for single user environment,and modeling process relies on the history of feature creating,this paper proposes a collaborative modeling system based on semantic feature modeling and a collaborative frame by combining B/S and C/S.This paper introduces the system＇s logical design and network realization.The project can provides a multi-users collaborative design environment and designers can edit the same feature model on network. Every designer can acquire the view that he wants through Feature Dependent Graph （FDG）,and because what the network transmits is not the entire image information,but modeling operation,the network has a less load and a faster respond speed.
