Research on Virtual Real-time 3D Space for Distance Education
Distance education has already been an important continuing education mode, but many courses including 3D (3-Dimension) objects can not be well supported in virtual classroom. In this paper, we propose an efficient solution to virtual real-time 3D space for distance education. In the proposed solution, a hybrid architecture is adopted to avoid the bottleneck of network communication and improve system responsiveness. Then, a concurrency control policy named rolebased optimistic token is introduced, which can not only identify the diverse authority among the participants but also guarantee the consistency of users view and improve the responsiveness of interaction. Finally, the virtual 3D space is implemented in the course of housing design, and several experiments are conducted to evaluate the performance of the 3D system. The application and experiments show that the architecture and the concurrency control strategy we proposed are efficient.
