图的深度优先算法动态演示，用到了直线的中点绘制算法-map algorithm for dynamic priority depth demonstration of the use of linear midpoint Rendering Algorithm

本程序是个示例程序,主要是演示计算机图形学的裁剪的中点分割算法.-this program is a sample program, mainly computer graphics demonstration of cutting the midpoint segmentation algorithm.

此源代码是介绍中点位移算法，并且能够运行显示结果-this source code is on the midpoint displacement algorithm, and can run results show
