Abstract
Compared with the traditional 2D electronic map navigation, the visual navigation has large amount of data. Especially when the viewpoint changes with high speed, navigation devices can’t display smoothly. Based on the above problem, this paper carried out the research from three aspects which could influence the speed of terrain visualization, that were the storage index of terrain data, data scheduling and occlusion culling. By adopting appropriate storage method, putting forward a new data scheduling strategy, and improving occlusion culling algorithm, the efficiency of the terrain rendering had been improved effectively. Experiments show that this method can meet the basic requirements of visual navigation.
