摘要
本文论述了基于嵌入式G IS的三维地形显示的一系列理论和算法。首先介绍了三维地形显示的基本算法步骤,接下来针对嵌入式系统的特点,提出了三个改进方面,分别是递归细分、坐标变换和内存调度。在论文的最后,给出了实验结果并进行了总结。
This paper introduces a series of theories and algorithms for 3D terrain display based on the embedded GIS.First,the basic algorithms for 3D terrain display are given.Then,according to the characters of the embedded system,the algorithms are improved through three methods,which are recursion,transform and memory schedule.The result is given at the end of the article.
