协同图形编辑系统的操作冲突及消解

Operation Conflict and Its Resolution in Cooperative Graphics Editing Systems

基于协同图形操作的丰富语意,在识别出对象几何属性与非几何属性操作的基础上,提出一个新的冲突模型及定义,它能更好地实现操作意愿维护,并已在原型系统CoDraftPaint的Undo算法中得到验证.

With the rich operation semantics of Collaborative Graphics Editing Systems,this paper proposes a new conflict model and a modified definition on the basis of the identification of the geometrical/non-geometrical attribution of the object.Having been successfully used in Undo solution of CoDraftPaint,a prototype of Cooperative Editing Systems,the new model proves to be able to achieve intention preservation better in Object-based Collaborative Graphics Editing Systems.
