在ArcEngine中实现地图的相交的矢量操作,Achieve in ArcEngine vector map of the intersection operation

这也是机械或汽车造型中用到的CAD曲线处理算法，可以把在平面上两条不相交的曲线拼接起来。-This is also the machinery or vehicle used in CAD modeling curve processing algorithms, you can put in the plane does not intersect the curve on the two spliced together.

BPF算法（回溯粒子滤波），还包括判断粒子是否有效的子函数，以及其中用到的判断两条直线是否相交的函数（用来判断轨迹是否与墙壁相交）。- three particle filter algorithms(SIR,ASIR and BPF) for indoor pedestrian navigation.Also include a function for particle validation detection and a function to check if two lines i

对本原蕴含中锐积，相交等各种计算都做了编程和改进，并把常见错误也列出-Plot for primitive contains the sharp intersection and other calculations are done programming and improvements, and also lists the common errors
