The VRML97 Specification was the second-generation predecessor specification that eventually led
to the X3D Graphics International Standard, maintaining full compatibility with the X3D ClassicVRML Encoding.
Many 3D graphics systems support the Virtual Reality Modeling Language (VRML97).
These scenes support the
Examples
section of the
VRML97 specification.
The baseline source kept under version control is in .x3d form, and the
autogenerated products include versions using the VRML97 .wrl file extension.
These examples are maintained for historic reasons and interoperability testing.
Backwards compatibility of scenes remains a significant strength of the
X3D specification,
which includes a fully interoperable
ClassicVRML file encoding
as well as numerous
conversion and translation tools.
Historic predecessor document references include the
VRML Script Node Authoring Interface
proposal of 6 October 1996, and the
Virtual Reality Modeling Language (VRML) 1.0 Specification
of 26 May 1995.
