Submitted to W3C Video on the Web Workshop; Real-time interactive 3D graphics and virtual environments typically include a variety of multimedia capabilities, including 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.

The article of record as published may be located at http://dx.doi.org/10.1109/MSP.2007.905889; Extensible 3D (X3D) is the open standard for Web-delivered three-dimensional (3D) graphics. It specifies a declarative geometry definition language, a run-time engine, and an application program interface (API) that provide an interactive, animated, real-time environment for 3D graphics. The X3D specification documents are freely available, the standard can be used without paying any royalties, and numerous implementations are available.

The Monterey Bay Aquarium Research Institute designed the Spatial Temporal Oceanographic Query System (STOQS) [MBARI 2014] to create new capabilities for scientists to gain insight from their data. STOQS employs open standards and is a 100% free and open source project. It includes a web-based graphical user interface where X3D Geospatial has been integrated to enable 3D geospatial data visualization.

New capabilities in web browser JavaScript implementations including networking, improved graphics performance, and improved speed allow the implementation of Networked Virtual Environments (NVEs) inside the web browser. An NVE can be written in JavaScript, which enables deployment in the enterprise entirely from a web server without the use of browser plugins. We discuss one implementation of this idea using X3DOM, an opensource implementation of the X3D standard written in JavaScript. The Open-DIS library for the IEEE Distributed Interactive Simulation (DIS) network protocol is used to create a partial implementation of the X3D standard’s DIS profile. Mechanisms for using the X3D DIS Profile DISEntityTypeMapping and DISEntityManager to enable run-time discovery and launching of new entities are discussed. Measurements of the capabilities and performance aspects of Websockets for network transport demonstrate excellent results.

X3D is the ISO-standard scene-graph language for interactive 3D graphics on the Web. A new course is available for teaching the fundamentals of 3D graphics using Extensible 3D (X3D). Resources include a detailed textbook, an authoring tool, hundreds of example scenes, and detailed slidesets covering each chapter. The published book is commercially available, while all other course-module resources are provided online free under open-source licenses. Numerous other commercial and open resources are available for X3D, which also serves as an interchange format. The supported course has been taught for many years, successfully introducing masters’ students to the principles and techniques of 3D graphics without requiring programming experience. This course is now ready for undergraduate use. Expressing 3D graphics modeling within the domain of Extensible Markup Language (XML) for the Web is novel and has the potential to open up computer graphics to many new practitioners. This combined resource is intended broadly support computer graphics education and 3D skills for web authors.

The article of record as published may be located at http://dx.doi.org/10.1145/2775292.2778306; Matlab is a powerful tool to compute high-fidelity engineering model and plot the result in figures. Simulink implements Matlab .m source code into block diagrams and flow charts to execute the simulation. This project demonstrates how physics equations implemented in Simulink can animate X3D or VRML models, along with the methods to convert Matlab .fig format into an X3D object so we can apply it into Web-based animations.
