stabbing
- 给定n维空间中的m个非空点集S1，…，Sm，如果直线L与每个点集均有公共点，则称L为这m个点集的一条直线穿越（line transversal 或 stabbing line）。同样，如果线段K（本文中的线段均指闭线段，且包括单点集）与每个点集均有公共点，则称K为这m个点集的一条线段穿越（segment transversal 或 stabbing line segment）。穿越的概念是海莱定理（Helly’s theorem）的延伸，它的存在性等问题一直是计算几何中海莱类定理（Helly-t

3DTERRIN
- DEM的规则格网存储结构是一个二维点阵,由于其高度与宽度已知,因此可以用一个一维数组p[n]进行管理，设原点的平面位置为(0, 0),DEM的长度与宽度分别为s和t,则任意一点(i,j)的高程值为p[i×t+j]。规则格网的这种简明结构,事实上已经对DEM数据进行了很好的组织,因此将格网数据读入内存，而无需使用其它任何结构进行管理,直接对读入的DEM数据块进行处理，生成格网面。 利用bitmap将DEM位图中的数据读入到程序数组中，其中规则网格将区域空间切分为规则的格网单元, 每个格网单元对
