Abstract
With the rapid development of computer software and hardware, the virtual reality is applied more widely. Interior 3D navigation, being as an important part of virtual reality and especially for 3D virtual roaming system, has become a hot research topic in recent years. In this paper, we propose a novel method to implement interior 3D navigation based on Virtual Reality Model Language (VRML). Firstly, the 3D tree routing map of an office building is obtained fro m the accurate AutoCAD model and with the support of block management strategy. Then, the roaming path by waypoint navigation method is generated. Finally, the interior 3D navigation system based on VRML is developed. By the automatic navigation, user can realistically experience the 3D indoor scene and the results test the validity of the proposed method in the engineering project.
