Multi-user shared virtual reality in the exhibition of Chinese nationalities-Virtual Museum of Chinese Nationalities

Virtual Museum of Chinese Nationalities is a multi-user shared virtual reality system developed to popularize the cultures and folk-customs of various ethnic groups for the public by means of cooperative work. We regard the project as long-term research, in that there are many problems to be solved. Unlike existing systems, we should maintain scalable and interactive performance on a wide variety of computing platforms, not only high-end graphics workstations, and distribute the virtual world via a bandwidth-limited network. We introduce some architectures and algorithms realized in our current prototype, e.g., shared event mechanism, area of interest algorithm, distributed server architecture, etc
