| 摘 要： | 将计算机图形学扫描线区域填充算法应用于地质科学计算可视化。是图形工程应用领域的扩展。这里应用改进扫描线算法，实现了复杂地质结构的地质属性填充的二维、三维剖面图绘制．为地质专家直观观察地质空间数据．有效分析空间数据提供了逻辑思维空间平台。这里分析了改进扫描线算法的实现技术思路，并讨论了剖面树ST和有效表AT的数据结构及其改进扫描线算法实现步骤和面向对象类封装的实现软件结构，最后还给出了该算法应用Delphi和OpenGL实现二维、三维复杂地质属性剖面图绘制实例。这些实例表明了这种算法是可行的。

| Abstract: | Filled algorithm of Scan line in the computer Graphicas used for visual calculate of geologic since is the extension of applying on graphic Engineering. A new algorithm of scan line is used to draw 2d and 3d graphics of geological attribute of complicated geological structure. It supplies the condition of direct observed and availability analyzed space data for the geologist. A new algorithm of scans line realized technical idea is analysed. Data structure about tree of geologic section (ST) , active table (AT), realized process of algorithm of scan line and object software structure are discussed in this paper. Some filled Graphics of 2D and 3D about complicated geologic sections based on Delphi and OpenGL of the algorithm are laited in the paper. The experimental results demonstrate the algorithm is reliable. |
