【Data structs】 four DL : 0: 四叉树递归此种模型绘制类似米字形的网格。由于整个过程递归调用绘图函数，所以可以根据误差判断绘制DEM的精细程度，从而绘制出不同精细程度的DEM，为解决漫游中数据量较大而引起的画面不流畅现象提供了模型基础。本文并没有对LOD作研究，只是给出了四叉树的建立和遍历绘图的方法。 -Recursive quadtree rendering such models similar character-meter grid. Recursive calls as a result of the whole process of mapping function, so it can be judged according to the error map of the fine DEM, thus rendering a different degree of precision DEM, for the settlement of roaming in the amount of data arising from the larger screen does not provide a model of fluid based on the phenomenon. This article does not LOD for research, but given quadtree traversal of the establishment and mapping method.

【OpenGL program】 mysf DL : 0: 地形漫游在仿真、模拟、虚拟现实等领域中有着广泛应用. 大规模地形的实时漫游算法一般采用视见体裁剪和与视点相关的连续细节层次等技术来减少实际绘制的地形数据量. 通过地形分块和视见体投影三角形扫描算法实现快速裁剪, 通过调整顶点的高度值消除裂缝, 通过基于三角形的四叉分割实现连续细节层次地形简化, 简化了算法实现, 提高了算法效率. 在没有利用帧连贯性的情况下, 算法可以在PC 机上实现较大规模地形的快速交互式漫游.-Roaming terrain in the simulation, simulation, virtual reality and other areas has a broad application. Large-scale real-time roaming terrain algorithm generally see as frustum culling and view-dependent continuous level of detail, such as techniques to reduce the actual rendering of terrain data. Through the terrain block and visually see the projector triangle body scan algorithm for fast cutting, by adjusting the height of peak value of the elimination of cracks in a triangle-based quadtree segmentation realize Continuous Level of Detail Terrain simplification simplified algorithm, improve the efficiency of the algorithm. In the absence of the use of frame coherence, the algorithm can realize in the PC, the rapid large-scale interactive roaming terrain.
