Presentation Transcript

  1. Extensible 3D (X3D) Graphics Open-standard open-source interactive visualization

  2. What is 3D? • 2½D works for chart-oriented displays • 3D 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

  3. What is X3D? • Extensible 3D (X3D) Graphics • Virtual Reality Modeling Language (VRML) updated • Third-generation ISO specification • Compatible XML .x3d and Classic VRML .wrl encodings • Deliverables • Specification updates, with compatible XML tagset • Multiple implementations, including open-source • Scene Access Interface (SAI) strongly typed API • Conformance suite and examples • Authoring capability: X3D-Edit, using XML for XML…

  4. 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 

  5. X3D Graphics for Web Authors • Don Brutzman and Leonard Daly, Morgan Kaufmann Publishers, May 2007. http://x3dGraphics.com • 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.

  6. X3D Specifications honeycomb diagram X3D Specification itself is componentized and extensible

  7. Context-sensitive, self-validating, multi-lingual editing tools X3D-Edit complete interface

  8. SAVAGE 3D Model Archive Lots of models!

  9. Scenario reconstruction, USS GREENVILLE collision with MV Ehime Maru 3D model library: collision USS GREENEVILLE

  10. Oahu Entire surface terrain of Earth available as X3D, via XML-based retrieval from ½TB binary DTED archive Oahu 3D model

  11. Numerous underwater vehicle models
