Interactive X3D Graphic

This interactive X3D tutorial, developed by Adela Crnišanin and Tatjana Jakšić, presents the basic properties of the Hubble Space Telescope. Users can explore fundamental components like the solar array, rear compartment, front compartment, and aperture door while learning about Hubble's orbit and functionalities. The tutorial provides a simple, attractive, and educational experience, showcasing how X3D syntax represents 3D objects and facilitating integration into web pages. Ideal for engaging presentations and enhancing web services like Wikipedia with 3D graphics.

  1. Interactive X3D Graphic Adela Crnišanin – State university of Novi Pazar Tatjana Jakšić – Mathematical Institute SANU Novi Sad, 2009

  2. Interactive X3D tutorial that is able to show basic properties of the main object. • Characteristic of tutorial - Simple - Attractive - Educational

  3. Assignment #4 • From CAD model make an X3D scene • Ask others did they like it and be honest about it when you make the presentation • Don’t forget to make web page, so the people outside your RLAB could see it

  4. Object of interest : Hubble Space Telescope We want to show the user: • names of the basic Hubble components • information about Hubble’s orbit • opportunity to circle around the Hubble

  5. X3D Hubble components • Solar array • Rear compartment • Front compartment • Aperture door • Antenna • Shield

  6. For description we use X3D syntax • Every component is represented as a node in X3D source code

  7. X3D • X3D is ISO standard • XML-based file format for representing 3D computer graphic • X3d scenes works over the internet via Http servers, a local disk drives or CDs and even as standalone email and chat attachments

  8. X3D used nodes • Inside of <xml> and <X3D> • Scene • Shape • Appearance • Material • Transform • TouchSensor • Text • In addition to nodes that represent the shape, sub nodes can describe different features of that shape

  9. Additional X3D nodes • TouchSensor node • Text inside Billboard Node • Script node (Java script) - function for processing exit • Route - for exchange information between nodes

  10. X3D file inside HTML • .X3D content can be integrated into web pages • We put .X3D scene inside <embed> tag • On html page, we provide some additional information about Hubble • To start X3D inside web page all we need is X3D browser OCTAGA

  11. Hubble object • Hubble is able to move around • Divided into several selected and defined field • Every selected and defined part has a event assigned • Interactive

  12. Conclusion • X3D is now part of the Webcompatibleinformation infrastructure • XML is license free, platformindependent and well supported • We think the usage of 3D graphics will be very useful to enhance features of some services like Wikipedia

  13. Thank you for you attention
