Visual Implement of Virtual Reality Tour Based on VRML

In this paper, a visual solution is presented about virtual reality tour of Web3D based on VRML. After analysis of polyline architectural structure related to tour route, a parametric definition of polyline is given, and a visual editor system of polyline is developed. With our experience on the VR project,the automatic generation algorithm is proposed about the VR tour based on VRML. The application shows that the proposed way can efficiently improve the performance quality of the project.
