ISO/IEC 14772, the Virtual Reality Modeling Language (VRML), defines a file format that integrates 3D graphics and multimedia. Conceptually, each VRML file is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. This part of ISO/IEC 14772 defines a mapping of the abstract objects in VRML to a specific encoding in binary format.
The semantics of VRML describe an abstract functional behaviour of time-based, interactive 3D, multimedia information. These semantics are realized by storing VRML information in a file. The binary encoding of such a file is herein.
Each VRML binary file:
A binary encoded VRML file may be referenced from files using other encodings and may itself reference other VRML files encoded using other encodings. Such files can only be processed by browsers which conform to all of the utilized encodings.
