WEB 3D What is it?  Combination of two powerful forces 

Armand Rousso

the internet  3D graphics 



The result: interactive, realtime 3D graphics delivered over the web with applications in online gaming  CAD, product demos, education, virtual tourism, real estate, and interior design 

TECHNOLOGY DRIVING WEB 3D X3D (eXtensible 3D Graphics)–Third Generation Web3D Standard

Armand Rousso



ISO open standard for (Web-enabled) interactive 3D  Started in 1995 with VRML 1.0  VRML 2 or VRML 97  X3D now and in the forseable future 



Aims to overcome the shortcomings of VRML 4
