VRML (Virtual Reality Modeling Language)

The VRML file format is a 3D-based model format originally created in the 1990's that was aimed at website usage. The format is text-based and contains 3D geometry data such as vertices, faces, simple shapes, material information, and more.

This format, when launched, was hoped to become a standard 3D format; however, due to the large file sizes, it didn't see wide adoption, although it is a supported format within some CAD software applications. It was later superseded by the X3D file format, which shares most of the functionality of VRML files.
