11. Virtual reality Modeling Language ( V R M L ) VRML produces a hyperspace (or a world), a 3- dimensional space that appears on your display screen. And you can figuratively move within this space. VRML provides three-dimensional world with integrated hyperlinks on the Web. Home pages become home spaces.

12. VRML is capable of representing static and animated dynamic 3D and multimedia objects with hyperlinks to other media such as text, sounds, movies, and images. VRML is more than an extension of HTML. Not a programming language like c++ or java. Descriptive (rather than procedural) like HTML. Characteristics of VRML
