We demonstrate the use of DASH, a widely-deployed standard for streaming video content, for streaming 3D content in an NVE (Networked Virtual Environment) consisting of 3D geometry and associated textures. We have developed a DASH client for NVE to show how NVE benefits from the advantages of DASH: it offers a scalable, easy-to-deploy 3D streaming framework. In our system, the 3D content is first statically partitioned into compliant DASH data, and metadata is provided in order for the client to manage which data to download. Based on a proposed utility metric for geometry and texture at the different resolution, the client can choose the content to request depending on its viewpoint. We effectively provide a Web-based client to navigate through our sample 3D scene, while deriving the streaming requests from its computation of the necessary online parameters, in a receiver-driven manner.
