VRML
The first version of VRML was specified in November 1994. It was specified from, and looked a lot like, the API and file format of the Open Inventor software component, originally developed by SGI. The development of version 2.0 was guided by the ad-hoc VRML Architecture Group (VAG). A working draft was published in August 1996. Formal collaboration between the VAG and SC24 of ISO began in 1996, and VRML 2.0 was submitted to ISO to be used as an international standard. The current and functionally complete version is VRML97 (ISO/IEC 14772-1:1997). X3D (ISO/IEC 19775-1) has succeeded VRML.
