X3D is the ISO standard for real-time 3D computer graphics, the successor to Virtual Reality Modeling Language (VRML). X3D features extensions to VRML (e.g. Humanoid Animation, Nurbs, GeoVRML etc.), the ability to encode the scene using an XML syntax as well as the Open Inventor-like syntax of VRML97, and enhanced application programmer interfaces (APIs).
August 2, 2006 - San Francisco, CA - The Web3D Consortium today announced that it has submitted a revision of the X3D specification for review by the International Standards Organization (ISO). This X3D Revision is the second update to the X3D specification since its unanimous approval as an international standard by ISO in 2004. It represents a significant advance in layering & overlays, physics, particle systems, smooth motion, and picking, enabling 3D simulations and web applications to implement features traditionally found only in high-level gaming systems. All features have been tested in real world applications, and been reviewed by hundreds of developers, before being incorporated into the revision.
