VRML

VRML (Virtual Reality Modeling Language, pronounced vermal or by its initials, originally—before 1995—known as the Virtual Reality Markup Language) is a markup language and file format for displaying 3D models in a web browser. It was developed partially by Silicon Graphics

WRL file format

VRML is a text file format where, e.g., vertices and edges for a 3D polygon can be specified along with the surface color, UV-mapped textures, shininess, transparency, and so on.[1][2] URLs can be associated with graphical components so that a web browser might fetch a webpage or a new VRML file from the Internet when the user clicks on the specific graphical component. Animations, sounds, lighting, and other aspects of the virtual world can interact with the user or may be triggered by external events such as timers. A special Script Node allows the addition of program code (e.g., written in Java or ECMAScript) to a VRML file.

VRML files are commonly called "worlds" and have the Template:Not a typo extension (for example, Template:Not a typo). VRML files are in plain text and generally compress well using gzip, useful for transferring over the Internet more quickly (some gzip compressed files use the Template:Not a typo extension). Many 3D modeling programs can save objects and scenes in VRML format.
