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.)

一个VTK的经典图像三维重建程序，里面有相关工程，程序，图片(A classic image of VTK 3D reconstruction procedures, which have related projects, procedures, pictures)

log算子检测斑点程序，程序可读性好，检测结果也不错，可以自行加载自己的图片进行检测(log operator to detect the spots on the program, the program readability test results are good, you can load your own picture to detect)

三维地形的模拟，用的工具是opengl，对于研究大规模地形的绘制非常有用，把源码拿出来与大家分享(Three-dimensional terrain modeling, using tools opengl, for the study of large-scale terrain rendering is very useful to share with you source out)

周期T=5，脉宽tao=1的矩形脉冲及频谱图(cycle T = 5, pulse width = tao a rectangular pulse and the spectrum)

本编程用于求解点到曲面的距离，快捷便利。(Solving the Distance from Point to Surface)

说明：  三维点云的伪彩色显示示例。自带5片点云用于测试。可平移、旋转、缩放视图；可单色、伪彩色显示点云。(An example of pseudo-color display of three-dimensional point clouds. It has five point clouds for testing. It can translate, rotate and zoom views; it can display point clouds in monochrome and pseudo-color.)

说明：  电磁波在均匀等离子体中的传输，等离子体密度适中(microwave propagation in uniform plasma)

用vtk+QT实现的MarchingCubes面绘制和光线投射体绘制，图形化洁面。(Surfacce rendering with MarchingCubes, Volume rendering with ray-casting, using QT+ VTK)

基于PCL的三维点云模型表面主曲率估计的具体实现(estimation of the principal curvature)
