凸包算法，运用分治的思想，用opengl显示出来-convex hull algorithm, the idea of partition, with opengl show

应用Graham算法查找散乱点集凸包，该程序演示了2D凸包的查找。按W键随机生成散乱点，并显示查找的最终凸包。-Find the convex of scatter points by graham algorithm. Press w key to generate random points, and the convex will be displayed.

算法设计 凸包问题 C程序开发的，需要配置OPENGL文件才能运行-tubao wenti suanfaseji good function program! have a good job ok la!
