摘　　要：以浏览器为载体,Web3D凭借其天然的跨平台、易访问优势,在虚拟现实、3D建模与可视化等数字内容领域展现广泛的应用前景。然而,研究如何构建多元、共享的沉浸式Web3D服务平台尚处于起步阶段。在应对网络环境动态变化、浏览器端渲染性能的限制及未来海量交互需求方面,如何确保无缝通信、计算和存储服务成为核心挑战。随着移动互联网、5G通信等前沿技术的推进以及边缘计算的兴起,Web3D服务模式正逐步从单一的终端或云端渲染方式过渡到边云协作方式,通过有效整合云端、边缘节点和终端用户资源来满足快速响应、数据速传、实时交互需求。围绕边云协同框架在沉浸式Web3D服务中的应用,探讨这一计算模式如何应对Web3D平台搭建中的复杂难题。首先,分析了面向Web3D应用场景的边云协同框架,以及边云协同在构建沉浸式Web3D服务平台时面临的关键挑战。其次,分别从资源调度、传输与加载策略、预缓存机制,以及模型轻量化的角度详细讨论了Web3D边云协同优化方案。最后,探讨了开放性研究问题。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.
