| 摘 要： | 主要探讨等值线三维显示及利用并行处理提高计算速度的方法。运用多边形填充和“画家算法”,实现了等值线三维显示 ;根据等值线数据量随其属性值而变化的特点 ,设计了采用“卷帘存储法”实现负载平衡的等值线三维显示的并行算法 ;采用“结合扇入法”实现结果合并 ,并采用“运行长度压缩法”以缩短网络通讯时间。在串行机上进行的模拟实验表明 ,所设计的并行算法具有较高的效率。

| Abstract: | Isoline 3-D display and its fast realizing by using parallel algorithm are studied in this paper. In the algorithm designed here, polygon-fill algorithm and "Painter Algorithm" are used to display 3-D isoline, "Windup Storage" method to balance computer processing load, "Associative Fan in" method to conflate results, and "Run Length Compression" method to save network communication time. The simulating experiments on serial computers showed this parallel algorithm works efficiently. |
