VRML ( Virtual Reality Modeling Language, sometimes pronounced vermal) is a standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind. It is a text file format where, e.g., vertices and edges for a 3D polygon can be specified along with the surface color , image-mapped textures, shininess, transparency, and so on. URLs can be associated with graphical component s so that a web browser might fetch a web-page or a new VRML file from the Internet when the user clicks on the specific graphical componentIn general, a thing's components are its parts; the things that compose it. In telecommunication and computing, a component is an assembly, or part thereof, that is essential to the operation of some larger assembly and is an immediate subdivision of the. AnimationThis animation moves at 10 frames per second. This animation moves at 2 frames per second. At this rate, the individual frames should be discernable. Animation refers to the process in which each frame of a film or movie is produced individually, whethers, soundThis article is about compression waves. For other meanings, see sound (disambiguation Sound is a mechanical compression and rarefaction or a longitudinal displacement wave that propagates through a medium (solid, liquid or gas). The speed of this propagas, lightingLighting refers to the devices or techniques used for illumination, usually referring to artificial light sources such as lamps or flashlights. Natural indoor lighting is by windows and skylights. Artificial indoor lighting is by means of lamps, today usu, and other aspectAspect can mean one of the following things: In computer programming, an aspect is a feature that is linked to many parts of a program, but which is not necessarily the primary function of the program. In linguistics, aspect is a grammatical feature havins of the virtual worldA virtual world is a computer-simulated environment intended for its users to inhabit and interact with via avatars. This habitation usually is represented in the form of two or three-dimensional graphical representations of humanoids (or other graphical can interact with the userIn telecommunication, the term user has the following meanings: 1. A person, organization, or other entity (including a computer or computer system), that employs the services provided by a telecommunication system, or by an information processing system, or may be triggered by external eventThere are many kinds of events In common language, an event is something that happens (changes), in particular something special of limited duration, for example a major football match or pop music concert. An event is an outcome, result, reference or sins such as timers. A special Script Node allows to add program code (e.g., written in Java or JavaScript (ECMAScript)) to a VRML file.VRML files are commonly called worlds and have the .wrl extension (for example island.wrl). Although VRML worlds use a text format they may often be compressed using gzip so that they transfer over the internet more quickly. Most 3D modeling program s can save objects and scenes in VRML format.
The Web3D Consortium has been formed to further the collective development of the format.
The first version of VRML was specified in November 1994. This version was specified from, and very closely resembled, the Application Programming Interface and file format of the Open Inventor software component, originally developed by SGI. The current and functionally complete version is VRML97 (ISO/IEC DIS 14772-1). The coming VRML standard is called X3D.
