A Replicated CSCW Framework for Multi-user Interaction in 3D Collaborative Design.

In order to support fast, freedom and natural multi-user interaction, a replicated framework for collaborative design of 3D solid model is presented. The framework combines general collaborative problems with special challenges from 3D design. In consistency maintain of multi-user interaction, an extended event order of operations is studied to integrate causal order and independent order based on semantic analysis of 3D design. A special consistency problem, the name consistency, is analyzed. A collaborative naming mechanism is provided with a case study. The proposed method will constructed the footstone to take the potential advantages of replicated 3D collaborative design. [ABSTRACT FROM AUTHOR]
