NVR: a system for networked virtual reality

Describes the design, implementation, and analysis of the NVR system. NVR is a software toolkit that facilitates the creation of networked virtual worlds. It uses the client-server network architecture, operates on low-end computer hardware, and allows for networking over the Internet. Design choices are described and explained. Techniques used by NVR that address problems inherent to networked virtual reality are presented. Other features of NVR are also described, such as NVR´s use of objects, server-moderated locks, local objects, and local changes. Observed performance of the system is then discussed. Finally, conclusions drawn from analysis of the system and suggestions for future work are presented
