协同图形编辑系统设计与实现

IMPLEMENTATION IN COOPERATIVE GRAPHICS EDITING SYSTEMS

给出了基于图形对象的协同编辑系统的操作冲突 /相容关系及其基于逻辑时间钟的检测方法和一致性保证算法。在此基础上 ,讨论了一个实时协同图形编辑系统的设计方面有关的关键技术。实验结果表明 ,该方法是可行和有效的。

In this paper,we first analyze the conflicting types and features in the object-based cooperative graphics editing system,and give the conflict and compatible relationship among operations.Then an approach is proposed for conflict detection between concurrent operations based on the object replication strategy,and the conflict of operations with multiple objects is also discussed.Finally,based on above methods,an integrated set of schemes and algorithms based on logical time are devised and discussed in detail.
