An interactive land use VRML application (ILUVA) with servlet assist

We summarize progress achieved on an interactive land use VRML application (ILUVA) with servlet assist. The purpose of this application is to enable one to take a virtual land area and add buildings, roadways, landscaping and other features. The application is implemented entirely using standard Web based technologies to allow fairly universal accessibility. The Virtual Reality Modeling Language (VRML) is a programming language that describes three dimensional objects and defines interactions associated with these objects. In this work, we show how the interactive capabilities can be expanded by employing Java servlets for recording user actions and for restoring prior sessions. The Java servlets offer several powerful capabilities including enabling logging permanent records of user sessions, retrieval of prior sessions, and dynamically generated VRML.
