Design and realization of really 3D visualization system for real-time rendering of large scale terrain
大规模地形真三维可视化系统设计与实现

Based on previous algorithms, this paper designed a new easy and fast terrain-rendering algorithm. Including the procedure of quad-tree generating, the texture automatic piecemeal, the terrain data database saves, view-culling, error-control and crack elimination conducted the thorough research and proposed a improvement method, unified the OpenGL stereo display technology, was realized succinctly based on the microcomputer platform, the fast large-scale really three dimensional terrain real-time plan prototype system, achieved a good visual effect and a high and steady FPS just on PC platforms. The exper-imental result indicates that, the algorithm realization is simple, the memory expenses are less, CPU consumed slightly, has a lower time and spatial expenses. It is suitable for the large-scale terrain really three dimensional real-time visible.
