Lahti International Week 2006 Introduction to X3D Lesson 1: Creating your models
Introduction to X3D Presented by : Peter Wilson, School of Computing & I.T. Wolverhampton University England Resources at:
Images on the Internet
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
HTML “HTML was designed to display data and to focus on how data looks.” * example: * Lahti International Week 2006 Welcome to this course on X3D We hope that you enjoy it
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! *
History of X3D Virtual Reality Mark-up Language (VRML) Started in D 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
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
X3D tags: Creating a box.
Basic structure of any model
Exercise 1: Your first X3D model Creating a simple box.
Exercise 2 Some simple shapes
Exercise 3: Street lamp This street lamp is made from standard shapes. Can you build it?
Exercise 4: Anglepoise lamp
Your turn! Produce your own object: E.g.
Summary That completes the lesson on building models in X3D. We have looked, briefly, at just a small number of the nodes available. Please your best model to:
