Virtual World Objects for Real Time Cooperative Design
Abstract
This proposition presents an architecture for “the rapid prototyping” of manufacturing products. This architecture satisfies the following requirements: cooperative design of a shared virtual world, concurrent and real time interactions of different users, dynamic distribution of the virtual scene among the different users, distributed world consistency, persistence and faults recovery. Currently, few solutions answer these requirements entirely. The virtual scene is distributed dynamically over private spaces according to the cooperative interactions. A user is aware in real time of operations carried out by other participants. A distributed concurrency control guaranties the consistency of a distributed scene. The persistence is provided in a distributed way. A user can go on working despite the faults of other machines.
