Integration of virtual reality and multimedia data in databases

Increasing capabilities of computer systems enable development of new, better ways of data visualization and interaction between users and computers. One of the most powerful mechanisms of data visualization and interaction is virtual reality. In this paper the use of virtual reality as a platform for multimedia presentations is proposed. A technique which enables common storage and retrieval of virtual reality and multimedia data in databases is presented. An appropriate modeling method for virtual reality data in databases and dynamic synthesis of their presentations is discussed. A geographic information system is described as an example.
