摘　　要：研究了基于Web的同步协同实体建模系统的设计及关键技术。该系统采用集中式结构,通过分布式服务对象为异地客户提供远程服务。系统采用增量传输来减少实体模型的数据传输量。通过改进Java3D数据结构,实现在Web界面下协同实体建模所需要的图形显示和交互功能。基于冲突预测符和操作序列筛选进行灵活的操作并发控制。A Web-based synchronized collaborative solid modeling system (WebCOSMOS), as well as the key techniques involved in implementing the system is presented. WebCOSMOS adopts the Client/Server architecture and provides remote services for distributed users based on CORBA. The system utilizes the incremental transmission to decrease the transmitted-data quantum of solid model, improves the graphics interaction capability under Web interface by extending Java3D data structure, and performs flexible concurrency control based on conflict prediction tokens and an operation filter.
