Study And Implementation Of A Real-Time Cruise System Based On 3D Terrain Visualization

Terrain visualization is an important part in many fields such as GIS, virtual reality and military simulation. Real-time cruise based on 3d terrain visualization is a hotspot in academic study. In this paper, we describe the realization process of 3d terrain real-time cruise system detailed. In order to deal with the difficulty in current study, we investigate different methods to generate digital terrain model and improve the algorithm of LOD digital terrain model at last. We use the quadtree structure to manage the terrain data, construct the evaluation model based on camera and terrain's roughness, and propose a project to eliminate crack between different LOD and reduce the image popping. In the end, we program to realize some crucial modules by OpenGL. Chen Zhiqiang(Computer Applied Technology) Directed by Prof. Song Yu...
