Abstract

Boolean operations are widely used in CAD applications to construct complex objects out of primitive ones. Conflict resolution of Boolean operations is a special and challenging issue in real-time collaborative CAD systems, which allow a group of geographically dispersed users to jointly perform design tasks over computer networks. In this paper, we contribute a novel conflict resolution technique that can retain the effects of individual conflicting Boolean operations by integrating them. This technique, named as CRIBO (Conflict Resolution by Integration for Boolean Operations), is in a sharp contrast to other ones that either desert the effects of some operations or keep the effects of different operations in different versions of the design. It is particularly good for collaborative CAD applications, where integration of different mindsets is a main source of creation and innovation. This technique lays a good foundation for resolving conflicting operations in design-oriented collaborative applications that require collective wisdom and stimulus of creation.
