MODELING Language.It is initials, originally known as the Virtual Reality Markup Language before 1995.It is a standard 3-dimensional (3D) interactive vector graphics representation file format, designed especially with the World Wide Web in mind.VRML is a text file format where, for example, it is possible to specify vertices and edges for a 3D polygon ALONG with the surface color, UV-mapped textures, shininess, transparency, etc.URLs can be associated with graphical components so that when the user clicks on a specific graphical component, a web browser can PICK up a web page or a new VRML file from the Internet.The user may interact with animations, sounds, lighting, and other aspects of the virtual world or they may be TRIGGERED by external events such as timers.A special Script Node enables the program code (e.g. written in Java or ECMAScript) to be added to a VRML file.VRML files are commonly REFERRED to as "worlds" and have the extension .wrl (for example, island. wrl).VRML files are in plain text and usually compress well using gzip.It is useful for faster transfers over the Internet (some gzip compressed files use the .wrz extension).Many 3D modeling programs can save objects and scenes in VRML format.Apartment Ground Plan in VRML
