Keynote Speech

Web3D Past, Present and Future: X3D Earth keynote slides

Don Brutzman, NavalPostgraduate School, Monterey California USA

Extensible 3D (X3D) Graphics has steadily progressed since work first began a decade ago. The Web3D Consortium is the public-private partnership of industry, agencies, universities and individuals that has "kept the flame alive" and made X3D what is today. Thanks to steady innovation by Web3D members, new X3D features continue to evolve and grow into great capabilities. Implementation, evaluation and then formal review by the International Standards Organization (ISO) have made X3D an approved standard for real-world use, both on and off the Web. Further collaboration with the World Wide Web Consortium (W3C) has made X3D a "first-class citizen" on the Web, providing excellent (and growing) interoperability with other XML standards.

Experience has shown that each accomplishment leads to important new challenges. The past and present of X3D are prelude to our next steps. In partnership with other contributing Web3D members, the NPS team proposes to use the Web architecture, XML languages and open protocols to build a standards-based X3D Earth usable by governments, industry, academia and the general public. The hardest parts of the technical infrastructure are already proven possible. Web3D Consortium members have the capabilities, resources and staying power to undertake this major new Web initiative. Prerequisites, partnerships, payoffs and next steps for Web3D will be discussed in detail.

Tutorial 2: Web3D Content Development: Lessons in Design and Theory tutorial slides

For more than a decade, web3D designers have created a wide spectrum of virtual content. Their creative ideas and innovative concepts have broken the boundaries of digital design. Novel techniques for visualizing and interacting with information can be found the educational simulations; visionary art projects, product demonstrations, playful games and shared virtual communities produced over the years.

This session offers a critical review of the concepts and content that have shaped web3D development. Broad theoretical constructs on the nature of virtual space blend with issues of practical application in a forum that will be both candid and controversial.

Topics in this tutorial include:

• Media Development, Lessons from Early Filmmaking
• Two Dimensional vs. Three Dimensional Design
• The Usability of Interfaces and Environments
• Game Design and Narrative Impact
• The Issue of Realism

Examples of works from leading designers will be shown and critiqued to understand what makes good Web3D design. The last 30 minutes will be an open discussion. Audience members are encouraged to bring their own examples of (and philosophies on) the nature of virtual content. The only prerequisite to this session is an open mind.

Presenter:Steve Guynup

One of the most creative and controversial figures in web3D, Steve is 10-year veteran in the field. He has presented virtual works at numerous conferences including SIGGRAPH 1998, 1999, 2000, 2003, 2004 and 2005 and written articles for NetProfessional 3D eZine and the William Blake journal Romantic Circles.

Tutorial 4: Creating Geo-Referenced 3D Cities Using COTS Tools tutorial slides whitepaper

Development of geo-referenced 3D terrain and city feature data, until recently, required the use of expensive, proprietary tools. It is now possible to produce accurate, realtime models using Commercial Off-The-Shelf (COTS) software.

Tutorial attendees will be walked through the entire production process, as used regularly in actual projects by the authors. This includes the acquisition of source data, use of the tools themselves, and the final project presentation. Demonstrations of projects created by this method will be shared with the attendees.

The tutorial will:

• Define the objectives of a sample project
• Outline the workflow necessary to obtain the objectives
• Identify and obtain source data for the area of interest
• Describe the tools required for the process
• Carefully go through the process step-by-step
• Present a final project deliverable within a web browser.
• Demonstrate other projects created by the same method.

For the tutorial, attendees should have a basic understanding of 3D graphics. Some knowledge of geo-referencing would be helpful, but not necessary.
