This presentation from members of the Web3D Consortium, Don Brutzman and Mathias Kolsch, was given at the “W3C Video on the Web Workshop”, held 12-13 December 2007, in San Jose, California, USA and Brussels, Belgium.
Real-time variety of multimedia capabilities, and virtual environments typically include a variety of multimedia capabilities, including videoincluding video. The Extensible 3D (X3D) Graphics is an ISO standard produced by the Web3D Consortium that defines 3D scenes using a scene-graph approach. Multiple X3D file formats and language encodings are available, with a primary emphasis on XML for maximum interoperability with the Web architecture. A large number of functional capabilities are needed and projected for the use of video together with Web-based virtual environments. This paper examines numerous functional requirements for the integrated use of Web-compatible video with 3D.
Three areas of interest are identified: video usage within X3D scenes, linking video external to X3D scenes, and generation of 3D geometry from video. Extensible 3D (X3D) is a Web-based standard for 3D graphics, enabling real-time communication using animation, user interaction and networking.
The point paper lists current and expected requirements, primarily divisible into usage of video within X3D graphics scenes, linkage to video in web-based applications external to X3D graphics scenes, and generation of 3D geometric content from spatially annotated video inputs.
