Edge-cloud collaboration empowered immersive Web3D

Leveraging the natural cross-platform accessibility, Web3D has shown wide application prospects in digital content fields with a browser as a carrier, including virtual reality, 3D modeling and visualization, to name a few. Nonetheless, constructing a diversified and shared immersive Web3D service platform is still in its infancy. How to ensure seamless communication, computing, and storage services has become a core challenge in dealing with the dynamic changes in network environments, limitations in browser-based rendering capabilities, and the impending surge in interactive demands. The progression of cutting-edge technologies such as mobile Internet and 5G networks, coupled with the emergence of edge computing, has propelled Web3D service modes from solitary terminal or cloud-based rendering toward a collaborative edge-cloud paradigm. Such a paradigm effectively integrates the resources from the remote cloud, edge nodes, and end users, thereby fulfilling the requirements of rapid response, high-speed data transmission, and real-time interaction. Focusing on the application of edge-cloud collaboration frameworks in immersive Web3D services, how this computing mode tackle the intricate issues encountered in establishing Web3D platforms was discussed. Firstly, a Web3D scenario-oriented edge-cloud collaboration framework and the key challenges faced in constructing immersive Web3D service platforms were discussed. Secondly, the optimization strategies for edge-cloud collaboration-driven Web3D were discussed from the perspectives of resource scheduling, transmission and loading, pre-caching schemes, and model lightweighting, respectively. Finally, open research questions were explored.
