ObjectivesSummarize X3D capabilities for engineering
Describe candidate architecture for sustainable generation, update and deployment of Interactive Engineering Tech Manuals (IETMs)
Discuss possible collaborations with NPS and industry partners
What is X3D? Extensible 3D (X3D) Graphics
•3D graphics for the Web•Royalty free•Third-generation ISO international standard •Compatible XML .x3d and compressed encodings•Approved for Navy use•Multiple commercial and open source products
What is 3D?
2½D works for chart-oriented displays3D gives “fly-thru” freedom of viewpoint• View physically based propagation paths• View depth separation• View bottom, surface interactions• View multiple overlapping sensors
Augment (not replace) existing displays
What is Web3D Consortium?Builds support for real-time 3D
communicationOpen non-profit organization for 3D on WebMultiple members
Commercial, organizational, educational, professional
Multiple standards-organization liaisons

Further X3D motivations
Authoring is hard, “Content is King”•X3D is not competing with specialty formats, instead provide common interoperability/interchange• Strong validation checks eliminate most authoring errors before content escapes• Plays well with next-generation Web languages
“3D hardware problem” is already solved
X3D Graphics for Web Authors
Don Brutzman and Leonard Daly, Morgan Kaufmann Publishers, May 2007. http://x3dGraphics.com 441 pages.
Building and interacting with 3D graphics is very much a "hands on" experience. Throughout this book there are lots of examples this book to help you learn how X3D works and assist you in building your own projects.
The book presents the essential ideas needed to understand how an X3D world works. The chapters of the book build upon each other progressing from simple ideas to complicated concepts.
X3D: Extensible 3D Graphics for Web Authors assumes that you are interested in learning more about 3D graphics. No prior programming experience is needed.
Free resources include many X3D example scenes, X3D-Edit authoring tool, chapter slidesets and online course videos.
X3D Profiles for ExtensibilityDifferent levels of
content complexityBrowsers can
support increasing levels of capability
Authors can use the proper palette for intended delivery
Candidate architecture of interest
Goal: sustainable generation, update and deployment of
multimedia manuals
Business case for X3DRoyalty free, open standard, extensibleStable, forward and backward compatibility,
suitable for long-term archival useWeb3D Consortium supports active working
groups if further features neededSupport by multiple industry partnersAvoid lock in, licensing costs, or potential
loss of company control over long term
Use casesEngineering referenceTraining and outreachShipboard installation and maintenance supportWatchstander logs, system monitoring, large-
scale emergency coordination
Hypertext, 2D, 3D, video, audio, simulationHandheld device, portable laptop, workstation
You have likely defined use-case details already

Exemplar project
IETM schema work in progress
Led by Mike Grimley NUWC for NAVSEA Integrated Warfare Systems (IWS) 6
Detailed v2.0 XML schema already produced• Exemplar effort that an EB project might follow• Docbook schema judged to be too large in scope
and not a good fit, understandably• Good documentation available
Might provide quick start to this candidate effort• Propose new project for integrated X3D content?
Additional discussion issuesGenerating animated simulated behaviorsArchiving and replaying behaviorsUse of integrated networking and chatSource code and training course availabilityResearch and development supportOther potential partnersLab visits are welcomeYour topics here…
Conclusions and Recommendations
XML, SVG, X3D are suitable for building IETMs, can add significant value to Navy and yards
Multiple X3D scene exemplars show Web-based graphics works, available in open source
NPS is Navy’s University, can partner on work. Further dialog and joint projects welcome.

What is X3D? 2
X3D is an initiative to leverage 3D as digital media as easily as we do with text and 2D graphics. It provides the technology to enable customers to view, modify, customize and reuse 3D visualizations in Web applications, or on any network device from cell phones to supercomputers.
See slide notes for many details.
X3D Specifications honeycomb diagram
X3D Specification itself is
componentizedand extensible
Example X3D browser architecture
A particular strength of X3D is that it does not tell software implementers exactly how to achieve results• Nor is a single “reference implementation” used
Instead innovation is allowed• Results are similar, improvements are ongoing
Following diagram shows “typical” architecture
Example X3D browser architecture
X3D compressed binary encoding
Two partial implementations now availableFurther compression now under consideration
