摘要

提出了一种基于块体的程序几何细节增强算法。增强算法采用海量模型作为处理单元。由于Chunklod算法缺少视点靠近地面的处理。增强算法将局部三角曲面简化算法与误差评估控制算法相结合，提高了渲染效率，避免了因过负载导致的大规模计算。最后，以地理信息系统为例，表明该算法在虚拟工作时能很好地表达地形信息的视觉效果，表明ChunkLod改进的细节层次增强算法是一种实用的全细节层次技术地形算法。

The Procedure Geometry Detail Enhancement Algorithm of Chunklod

This paper represents the Procedure geometry detail enhancement algorithm of Chunklod. The enhancement algorithm adopts massive model as processing unit. Because the Chunklod algorithm lacks process that viewpoint is near to the ground. The enhancement algorithm improves the efficiency of rendering by combining the local triangle surface simplified algorithm and the error evaluation & control algorithm, it avoids large-scale computing caused by over-LOD. Finally ,the paper shows that the visual effect of terrain information is expressed well when the algorithm is working virtually-taking the geographical information system for example .The results indicates that the improved level of detail enhancement of ChunkLod is a practical terrain algorithm with total levels of detail technology.
