计算几何中的几种lisp语言的算法，包括凸包，最小包围圆，点集的最大直径，最小距离等。-computational geometry of several lisp language algorithms, including the convex hull, the smallest enclosing circle, Point Set diameter of the largest and the smallest distance.

利用MFC，简单的图形界面，简单的算法，实现凸包的绘制-Using MFC, a simple graphical interface, a simple algorithm to achieve the convex hull of the draw

用C#编写的计算凸包的程序，可以运行，代码简单。-Calculated using C#, the convex hull of the program, you can run the code simple.

实现凸包算法，可以清晰的看见递归的过程，也可以看出最后的区域-Convex hull algorithm recursive process, you can clearly see, the last area can also be seen
