Résumé

Version 2.0 of the Virtual Reality Modeling Language allows world designers to create interactive animated 3D virtual worlds. The VRML 2.0 Handbook guides readers through the development of such a world, using a VRML reconstruction of the Aztec city Tenochtitlan. This guide offers practical, platform-independent tips and examples from the experts at Silicon Graphics, Inc., leaders in formulating and developing VRML. Detailed examples and diagrams provide a solid foundation in VRML 2.0 for a wide range of content creators, from artists and designers with little programming background to seasoned computer experts with modest graphics skills.

With VRML 2.0, you can create robots and people that walk and run, dogs that bark, and gurgling streams. You can design objects that react to user actions, such as doors that open when clicked. You can include sensors that respond when the user approaches a certain area--triggering an alarm, for instance, or starting an animation. This handbook explains how to use all of VRML 2.0's features, including:

movies and 3D sounds
visual effects such as fog and scenic panoramas with mountains, plains, or cityscapes
collision detection, which prevents users from walking through walls
sensors that keep track of the passage of time and respond to user actions such as clicking an object or moving to a certain location
interpolators, which make it easy to include key-frame animation in your worlds
the Script node, which allows you to write mini-programs in a language such as JavaScript or Java™, to build logic into your VRML world
a prototyping feature that allows you to package objects you create and let other world authors use and modify them.

Jed Hartman has written about the OpenGL™ graphics library and IRIS Performer, as well as other developer tools, at Silicon Graphics, Inc. Josie Wernecke, also a member of the Silicon Graphics staff, is the author of The Inventor Mentor and The Inventor Toolmaker and has written extensively about Open Inventor™ and other 3D graphics products.
Delle Maxwell, award-winning animator and graphic designer, developed the Tenochtitlan site described in the book from a model created by Bob Galbraith of Computer Graphics.

The accompanying CD-ROM contains VRML utilities and code featured in the text.
