WebGL brings plugin-free 3D to the web, implemented right into the browser. Major browser developpers Apple (Safari), Google (Chrome), Mozilla (Firefox), and Opera (Opera) are members of the WebGL Working Group.
WebGL is developped by the Khronos Group, a not for profit, member-funded consortium focused on the creation of royalty-free open standards for parallel computing, graphics and dynamic media on a wide variety of platforms and devices. The Khronos Group was founded in January 2000 by a number of leading media-centric companies, including 3Dlabs, ATI, Discreet, Evans & Sutherland, Intel, NVIDIA, SGI and Sun Microsystems.
A guide how to get a WebGL implementation is available at the Khronos wiki website.
The current stable version of the Google Chrome 8 browser can be WebGL enabled by entering about:flags in the address bar and enabling the feature. A better (default) support of WebGL is provided with the Google Chrome Canari browser (the development version 10.0.614.0).
