Abstract

With the rapid development of mobile Internet, terminals of 3D GIS (geographic information system) applications have become more and more diverse. The current web visualization methods can hardly meet the requirements of diverse terminals. To solve this problem, an adaptive visualization architecture based on the B/S (browser/server) model was designed. Then some key technologies were explored, such as the diverse organization of 3D data, adaptive quad-tree organization, construction of dynamic index and adaptive scheduling of 3D scene. Finally, a prototype system was developed on the basis of WebGL. The experimental results show that the rendering frame rate of the laptop computer is eventually stable at more than 40 frame per seconds, that of the smartphone and tablet computer is eventually stable at more than 20 frame per seconds, and web visualization on diverse terminals can be ensured with high visual efficiency and effects, thus demonstrating the effectiveness of the proposed method.
