简单的实现物体表面三维坐标的提取，实现过程是利用相机两次在两个位置拍摄同一物体，通过一定的算法实现。-Simple surface extraction of the three-dimensional coordinates, the implementation process is the camera twice in two locations to shoot the same object, implemented through a certain algorithm.

VTK实验程序，利用VTK开源库实现Marching Cubes等值面提取算法，程序中可修改等值面参数，交互界面实现物体的旋转、缩放，数据文件在工程目录下-VTK experimental procedures, the use of open-source library implementation VTK Marching Cubes isosurface extraction algorithm, the program can be modified isosurface parame
