Engineering Virtual Environments with X3D

Date: Tuesday 29th March
Time: 2pm - 2 x 90 minute sessions
There are a number of important challenges facing developers of networked virtual environment applications, not just knowledge of various authoring tools, formats, and runtime engines. This session examines the approaches and supporting technologies for the delivery of interactive 3D content over the network. We will consider the issues and tradeoffs in publishing content with X3D using common XML and server tools. The rational design and composition of scene resources is crucial to a successful project deployment and attendees will gain an understanding of applied IT architectures using standard scenegraphs, data, and webservice paradigms.
Topics in this tutorial include:
Techniques covered in this tutorial:
Case studies will be used to illustrate architectural choices for delivering interactive 3D content in a number of application areas including:
For the tutorial, a basic acquaintance with the VRML and X3D nodeset and common web publishing technologies is required.


Authors:

Nicholas F. Polys has worked in the creation and management of digital assets for virtual environments for more than 6 years. From 1999-2002, Mr. Polys served on the Web3D Consortium Board of Directors and produced the Consortium's semi-annual Software Development Kit. As a key contributor to the X3D specification, Nicholas has conducted courses including: Introducing X3D (SIGGRAPH 2002 and local chapters: Boston, San Francisco), and Graphics Publishing with X3D (Web3D 2002). Mr. Polys has published on cutting-edge techniques for design and publication of real-time networked 3D in the ACM, IEEE, SPIE venues and a recent book chapter. His current research at Virginia Tech and the Virginia Bioinformatics Institute concerns Human-Computer Interaction and 3D user interfaces for Information-Rich Virtual Environments.
Don Brutzman is a computer scientist and Associate Professor working in the Modeling Virtual Environments & Simulation (MOVES) Institute and Undersea Warfare Center at the Naval Postgraduate School. His research interests include underwater robotics, real-time 3D computer graphics, artificial intelligence and high-performance networking. He is a member of the Institute of Electrical and Electronic Engineers (IEEE), the Association for Computing Machinery (ACM) Special Interest Group on Graphics (SIGGRAPH) and the American Association for Artificial Intelligence (AAAI). He is a board member of non-profit Sea Lab Monterey Bay, which is designing and building a youth-oriented year-round residential science camp. He is a founding member of the non-profit Web3D Consortium Board of Directors. He organized and led the SIGGRAPH Online 2001 team, designing and developing a huge audio/video/Web/XML information architecture. Currently he cochairs the Extensible 3D (X3D) Working Group for the ISO X3D/VRML Specification, and directs development of the Virtual Reality Transfer Protocol (vrtp) and the Extensible Modeling and Simulation Framework (XMSF).
