3D graphics became ordinary first in games, then in operating systems, and on Thursday, it took a significant step toward being built into Web browsers as well.
The group now wants commentary from Web developers and others who might be involved with WebGL so it can be finalized. "I anticipate us moving toward a spec that is not provisional, not merely a draft, in early 2010, the first quarter," said Arun Ranganathan, chairman of the WebGL working group and standards evangelist at Mozilla.
Internet Explorer remains the dominant browser in terms of usage, but all four of its main challengers--Mozilla's Firefox, Apple's Safari, Google's Chrome, and Opera Software's Opera--are working hard, sometimes in an informal alliance, to get ahead by advancing the Web state of the art.
WebGL fits into that effort, and not just academically. All four of those browser makers have endorsed WebGL, and developer test versions of, and have it built in. Microsoft declined to comment for this story beyond reiterating its general support for standards.
Ultimately, building 3D support into the Web could advance user interfaces of Web applications--including games, the popularity of which can be a powerful incentive for upgrading to the latest technology.
It's not clear exactly how it will play out, though, Ranganathan said. The arrival of Canvas, an advanced 2D interface for browsers, has led to a blossoming of graphics work, and he expects a similar change with 3D graphics.
But don't hold your breath for Web-based first-person shooters that rival native applications. First, even if 3D is accelerated, there are plenty of other processing and user interface constraints on Web applications. Second, even after WebGL is standardized, it must be built into browsers, people must upgrade to those new versions, and programmers must learn how to support the technology.
WebGL isn't the only 3D Web work under way. Google has its own O3D project, which currently is a browser plug-in but that the company also is .
And of course, a decade ago there was VRML--virtual reality modeling language, a file format rather than interface. A VRML successor called X3D, though, can actually make use of WebGL, and indeed a project called X3dom aims to do just that.
