VRML for urban visualization

A virtual reality modeling language (VRML) based application has been developed as a marketing tool for a commercial park. VRML is a new Web based technology for specifying and delivering three-dimensional interactive visualizations over the Internet through a Web browser. As a part of its definition, VRML includes primitives that specify geometries, sense different conditions in in the visualization, and allow custom definition of methods. Geometries and conditions may be linked so that the geometries can be modified or added interactively. The visualization features simple operation, an extensive menu structure, dynamic creation of objects, and an arbitration scheme.
