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: * http://www.w3schools.com/xml/xml_whatis.asp Lahti International Week 2006 Welcome to this course on X3D We hope that you enjoy it

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: * Tove Jani Reminder Don't forget me this weekend! * 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.

10. Basic structure of any model

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
