  1. Lahti International Week 2006 Introduction to X3D Lesson 1: Creating your models

  2. Introduction to X3D Presented by: Peter Wilson, School of Computing & I.T. Wolverhampton University England Resources at: http://www.scit.wlv.ac.uk/~cm1949/Lahti/Index.html

  3. Images on the Internet

  4. Brief History of X3D • Internet: • Prototype Web browser – 1990 • Text only • Pictures soon added – static, then animated • Virtual Reality Modelling Language (VRML) • 3D models over the web – from 1994

  5. HTML “HTML was designed to display data and to focus on how data looks.” * example: <body bgcolor="yellow"> <h2> Lahti International Week 2006</h2> <p> Welcome to this course on <b>X3D</b></p> <p> We hope that you enjoy it </p> </body> * http://www.w3schools.com/xml/xml_whatis.asp

  6. eXtensible Mark-up Language “XML was designed to describe data and to focus on what data is.” * • You define your own “tags” • You need some other software to use the data. XML example: * <note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note> * http://www.w3schools.com/xml/xml_whatis.asp

  7. History of X3D • Virtual Reality Mark-up Language (VRML) • Started in 1994 • 3D modelling system running over the Internet • New version, to fit in with XML, is X3D. • Uses a pre-defined set of tags • Interpreted by Internet browser into a 3D model

  8. Creating and Viewing X3D files To view X3D files: A browser plug-in such as “Flux” (you will have used other plug-ins to view Flash files, etc) To create X3D files: A simple text editor e.g. Microsoft Notepad A specialist X3D editor e.g. X3D-Edit Exported from a 3D modelling package

  9. X3D tags: • Creating a box. <Shape> <Box size="2 1 1"/> <Appearance> <Material diffuseColor="0 0 1"/> </Appearance> </Shape>

  10. Basic structure of any model <Transform ……..> <Shape> <Box ……> <Appearance ….> <Material ….>

  11. Exercise 1: Your first X3D model • Creating a simple box.

  12. Exercise 2 • Some simple shapes

  13. Exercise 3: Street lamp This street lamp is made from standard shapes. Can you build it?

  14. Exercise 4: Anglepoise lamp

  15. Your turn! • Produce your own object: • E.g.

  16. Summary That completes the lesson on building models in X3D. We have looked, briefly, at just a small number of the nodes available. Please email your best model to: P.I.Wilson@wlv.ac.uk
