A creative approach to conflict detection in web-based 3D cooperative design

In the process of web-based 3D cooperative design, it is difficult to avoid concurrent design conflicts among designers. B/S structure requires that most computational work must be done in service side, so conventional solution to desktop-based cooperative system is not well applicable to web-based one. Therefore, during the conflict detection process, when to make conflict detection, conflict resolution and broadcast result operations to all cooperative sites become a key problem. In this article we propose a novel web-based 3D cooperative design framework and a concrete implementation to conflict detection.; By this framework we can achieve automatic operation submission, realtime conflict detection based on dynamically adjustable time, and automatic conflict resolution with designers’ customization, which is much different from conventional solutions that require frequent participation of designers to submit changes and resolve conflicts. And through tests and analysis our solution shows good performance, scalability and design interactivity. © Springer International Publishing Switzerland 2014.
