Bezier,B样条曲面，同时又一个实例，以及给定16个点，可以自动画出Bezier,B样条曲面，可以选择是否显示控制网格-Bezier, B-spline surface, but also an example of, and given 16 points, automatically painted Bezier, B-spline surface, can choose whether or not to display and control grid

给定栅格图像及其变形后的栅格图像，请你首先确定各栅格交叉点的位移，然后采用控制栅格的方法编写实现图像几何校正的程序-Given its raster image raster image after deformation, you first determine the displacement of each grid intersection, and then using the method of preparation of the control grid of image geo
