VRML (Virtual Reality Modeling Language)

VRML (Virtual Reality Modeling Language) was developed around 1994 as a means to share 3D environments, targeted primarily at the world-wide web. Its specification includes several environmental primitives, including a surrounding cube. The cube is texture-mapped, and provides a backdrop behind a scene composed otherwise of polyhedral objects. This cubic environment map is the one advocated by Greene in his 1986 paper.
