清华大学本科生课程设计，实现平面点集的三角剖分！用外接圆测试剖分的正确性。算法执行速度较快，但存在狭长三角形！(Tsinghua University undergraduate courses designed to achieve the triangulation of the set of points in the plane! Circumcircle test the correctness of the split. Algorithms perform faster, but there is a long, narrow triangle!)

说明：  能花线，圆，矩形，正方形 能选者颜色，能选者填充的背景图案 (can spend line, circle, rectangle, square color who can be elected, who can be elected to fill the background logo)

说明：  顶帽变换的程序，能够实现平滑图像的效果。(Cap transformation process, to achieve the effect of smoothing the image.)

迭代最邻近点算法进行3D点云的匹配，四元数方法求旋转(ICP algorithm for point clouds)

Voronoi图是以两点间线段的长度作为距离 ,对平面的一种分割。然而 ,在地理环境中 ,存在着许多自然的或人为的障碍 ,使得从一点到另一点不能直线到达。为了扩大Voronoi图的应用领域 ,本文对传统的Voronoi图进行扩充 ,给出了障碍Voronoi图的定义、性质 ,以及离散生成线段障碍Voronoi图的方法(Voronoi diagram based on the length of line between two points as the distance from a partition of the plane. However, in the geographical environment, there are many natural or man-made obstacles, making from one point to another point of arrival can not be a straight line. In order to expand the area of Voronoi diagram, Voronoi In this paper, the traditional expansion plans, given the obstacles to the definition of Voronoi diagram, the nature of the discrete Voronoi diagram generation segment of the barrier method)

这是我所下载的SSNF算法（SSNF算法基于小波变换尺度间相关性的去噪）(This is what I have downloaded the SSNF algorithm (SSNF algorithm based on wavelet transform correlation between the scale of the noise))

图形填充，单击画图形，双击后在封闭图形内填充图案(The graphics filled, click painted graphics, double-click in the closed graphics fill pattern)

用于求取三维点云数据的法向量，我的人脸建模就是用的这个，效果很好，但必须保证点云没有重叠的，否则会出现严重错误。(Strike a 3D point cloud data for normal vectors, and my face is to use this model, the effect is very good, but must ensure that there is no overlap of the point cloud, there would be a serious mistake.)

可以用于画世界地图。这个函数可以通过控制经纬度画不同范围的世界地图。(Can be used to draw the world map. This function can be painted by controlling the latitude and longitude of different areas of the world map.)
