Mu3D

Abstract

This paper describes the implementation of the Mu3D application protocol and consistency control mechanisms to allow the collaborative editing of CAD design. The collaborative editor (M3D editor) developed by us is VRML compliant. The editor has been used as a base for the European Esprit project No. 26287 -M3D and the Spanish project TEL 96-0544/CODI for Cooperative CAD applications.In our system, only the changes to local databases are transmitted to other collaborative session members. To assure database consistency, the system provides consistency control over the shared data space. A great effort has been paid also to provide a high capability of cooperation and user interactivity while narrowing networks bandwidth requirements.
