N2 - Multi-stream/multi-site 3D video collaborative systems are promising as they enable remote users to interact in a 3D virtual space with a sense of co-presence. However, the decentralized content dissemination remains a challenge. In this work, we explore approaches to construct adaptive overlay based on the users' visual interest in the collaborative space. Particularly, we consider the practical challenge that the user's interest might change dynamically. We propose, compare, and evaluate three algorithms to handle the view dynamics. With extensive experiments, we demonstrate that an algorithm that exploits view locality can achieve efficient bandwidth utilization, high topology stability, and great scalability.
