X3D 101: The extra dimension to the Web

X3D 101: The extra dimension to the Web: "

As science-fiction flavored as the Internet once sounded, X3D, which in essence opens the Web to three dimensions, represents the next real-world leap of such technology. This open-standards file format and run-time architecture allows you to view, create, store, and share three-dimensional objects over XML (Extensible Markup Language).
X3D, it can be argued, is taking the baton from VRML (Virtual Reality Modeling Language), from which it evolved—thanks, in part, to applicable feedback from the development community. Industries and disciplines that benefit from X3D include multimedia, entertainment/gaming, medicine/health care, architecture, engineering, and science. "

Steve's Commentary
The VRML standard never seemed to get a lot of traction. Maybe this has a better shot, but it will have to compete with a lot of proprietary formats. It will be interesting to see how 3D worlds like Second Life leverage or compete with these open standards. SL's recent release of its source code may open doors to more compatibility.
