We introduce the network software architecture of the distributed interactive virtual environment platform. The platform is designed to scale with a large number of simultaneous participants, while ensuring maximum interaction at each site. Scalability is achieved by making extensive use of multicast techniques and by partitioning the virtual space into(More)
Building a distributed virtual environment that scales to many participants in low bandwidth, high latency networks is a technical challenge. The key issues are maintaining acceptable performance in the face of high latency links, and maintaing consistency of shared world data between multiple participants. This paper describes our overall architecture that(More)
A central aim of the COVEN project was to prototype large-scale applications of collaborative virtual environments (CVEs) that went beyond the existing state of the art. These applications were used in a series of real-scale networked trials that allowed us to gather many interesting human and technological results. To fulŽll the technological and(More)
To allow the number of simultaneous participants and applications to grow, many Collaborative Virtual Environment (CVE) platforms are combining ideas such as loose consistency, absence of central servers and world sub-partitioning with IP multicasting. For long distance connections, most of these systems rely on the existence of the Internet multicast(More)
In an attempt to reduce the communication costs in a shared distributed virtual environment (VE) system with a large number of participants, we have explored the use of SP* tial interaction techniques. In particular, we have experimented with the notion of an area of interest (AOI) which is dynamically established based on the spatial proximity of(More)

In this paper a model for collaboration between engineers in a distributed virtual environment, based upon a suite of specialised computer tools is presented. The system uses the distributed virtual reality system DIVE, which has been customised to allow interoperability with existing CAD systems. Other tools implemented to support information exchange in a(More)
1. ABSTRACT The Blob was developed as an initial part of the MIMOID project [1] which is an interactive mini opera based on ideas from Stanislaw Lem's novel Solaris [2]. Musicians, artists and technicians jointly developed the Blob as a piece of the scene for the opera, the Solaris planet covered by an organic and chaotic ocean. A short live-performance(More)
