基于GPU的大规模地形数据绘制算法

摘要

In the process of rendering for large terrain, producing images clearly and accurately are required. This paper puts forward the reasonable solution from the organization of the real-time terrain data, drawing LOD selection standards, LOD optimization and optimization of view frustum culling. The result shows that the method can make full use of CPU draw, which can be applied to rendering for large scale terrain.%针对大规模地形数据绘制中,对绘制过程快速、生成图像清晰准确的要求,从地形数据的组织、实时绘制时LOD选取标准、层次过渡优化、视锥体裁减等地形可视化的几个关键技术层面着手,提出合理的解决方案.生成的结果表明,该方法能够充分利用GPU进行绘制,可以适用于大规模地形数据绘制.
