MPEG-4 BIFS streaming of large virtual environments and their animation on the web

摘要

Although the Virtual Reality Modeling Language has made viewing 3D content on the web possible, remotely accessing large and complex 3D worlds requires a great deal of bandwidth. In the absence of such bandwidth users will suffer substantial latency in receiving the entire scene before they are able to view and interact with it. Streaming the 3D content and displaying the parts currently available while allowing users to interact with and navigate through the world reduces the time users have to wait in order to become involved in the virtual scene and hence improves their experience. This paper presents the use of the MPEG-4 standard for streaming of 3D worlds and the corresponding animation over the web while allowing users navigation and manipulation of the content, as it becomes available.
