A Simple and Effective 3D Navigation System with 2D Map Guidance

: This paper presents a 3D scene modeling method for a Simple and Effective 3D Navigation (SE3DN) system, with 2D map guidance and multimedia information. SE3DN constructs 3D models and 2D maps of the scene from a series of CAD drawing data. First, the outline model of the scene is created with the CAD data. Then, a 3D model of each building is created with its height information using a geometry-based modeling technique. Finally, textures are pasted on the surface of all buildings and objects in the scene to get photo-realistic effects. Advantages of the proposed method are: 1) Ease in accurate alignment of separate modules to specific positions in the scene; 2) Ease in accommodating changes in the scene; 3) Unrestricted selection of views by the user. The details in the development of this kind of systems are reported.
