我本人做的一个拾取算法实现的程序，主要是利用鼠标以及摄像机生成的射线进行判断，图像可以用鼠标进行拾取-I do a pickup algorithm procedure, mainly using the mouse and the resulting ray camera to judge, the image can be picked up with the mouse

该算法建立了由最小二乘法,离散点曲率和离散点曲率变化和三项组成的目标函数并求出了最优控制点序列坐标,采用非线性优化方法对权因子序列进行了调整,确立了逼近误差的近似表示方法,并提出了包括上述方法的循环判断流程.-The algorithm was established by the least squares method, discrete points, the curvature and the curvature change and the three discrete points

判断点是否位于平面上（三维）。 原理：将平面方程变f(x) = 0的形式，将点的坐标代入f(x)中，若点位于平面上,则f(x)为0，若点位于平面两侧, 则f(x)值正负号相反，由此可判断此点位于面的哪一边。 可在CPointPlaneDlg::PlaneEquation()对点和面的数据进行修改。-The relationship between point and plane，determine whether the point in the plane
