3D Virtual Community Building Applications in PANIVE ArchitectureFlerackers, C.; Chilton, Nicholas; Earnshaw, Rae A.; Lamotte, W.; Van Reeth, F. (2000)PANIVE (PC-based Architecture Networked Interactive Virtual Environments) is an extensible architecture in which various networked virtual environment applications can be realized. This chapter describes our efforts in realizing applications in the area of “3D virtual community building”, in which people can virtually meet each other, speak to each other, interact with each other, etc. in a virtual equivalent of conventional social communities. The overall architecture will be discussed briefly. Some attention will be given to the realization of the audio component in the system (speech input and 3D sound output) that supports intuitive interaction among the participants in a shared virtual environment. The main part of the chapter discusses and illustrates some demonstrative example applications that highlight the potential for realizing 3D networked virtual communities in the architecture.
VISINET: Collaborative 3D Visualization and Virtual Reality over Trans-European ATM NetworksLamotte, W.; Earnshaw, Rae A.; Van Reeth, F.; Flerackers, E.; Mena de Matos, J. (1997)Visinet is a trans-European 3D collaborative design project that brings together computer scientists, application developers, design specialists, and users in the context of shared environments supported by ATM networks. Experiments and trials have been conducted for the key application domains of architectural and industrial design. Different types of virtual representation and computer-supported collaborative work are applied to real-life projects between partners at different locations in Europe. Measurements of network requirements have enabled cost/benefits to be quantified. Measurements of user satisfaction and speed of completion of the design to product cycle have also been made, resulting in a greater understanding of the ways in which collaborative design environments linked by high-speed networks affect this cycle. Additional experiments are currently being conducted on the way in which an ATM backbone between principal partners in a project can be complemented with ISDN links to partners in a local area.
