Recently, Google made public a series of informations about a new project called "O3D". In the words of their developers, it is:
"...a new shader-based API for 3D graphics in the browser"So this is something similar to Khronos, and seems there is some will or space to combine it with Mozilla's Canvas 3D. The O3D API will allow web developers to create 3D applications that want to reach the quality of game consoles. O3D is now available as a plugin for Chrome, Firefox, Internet Explorer, and Safari, and for Windows, Mac and Linux: http://code.google.com/apis/o3d/
My personal comments: I already went ahead and installed the Google O3D browser plugin on my PC and gave this a try. What I saw was very interesting, a 3D virtual world with high res textures, hardware accelerated graphics and streamed in real time through the web browser. The scene that I tested was the one called "Beach scene". Now, I heard some people say that the graphics of O3D are on par with the PS3, but that's something to debate.
Now, there is also another thing about Google trying to push this new web-3d standard initiative that's in conflict with an already established web-3d technology standards put forward by the official web3d consortium ( http://www.web3d.org/ ), which happens to be a branch of the main World Wide Web Consortium (W3C). The already established Consortium standards for web-3d is the format X3D, along with it's older version VRML.
