Abstract:
Distributed Interactive Virtual Environment (DIVE) is an internet-based multi-user VR system where participants navigate in 3D space and see, meet and interact with other users and applications,DIVE applications and activities include virtual battlefields, spatial models of interaction, virtual agents, real-world robot control and multi-modal interaction. DIVE supports the development of virtual environments, user interfaces and applications based on shared 3D synthetic environments. DIVE is especially tuned to multi-user applications, where several networked participants interact over a network.
Dynamic behaviour of objects are described by interpretative Tcl scripts evaluated on any node where the object is replicated. Scripts are triggered by events in the system,Dive is based on a peer-to-peer approach with no centralized server, where peers communicate by reliable and non-reliable multicast, based on IP multicast. Conceptually, the shared state can be seen as a memory shared over a network where a set of processes interact by making concurrent accesses to the memory
