三维数据点拟合空间球体的算法，利用最小二乘法实现空间球的拟合。-3D data points fitting the space sphere algorithm using the method of least squares fitting space ball.

离散点是数据管理,采用4叉树的管理方式,对于搞图形算法的人员还是很有帮助的.渲染采用OSG,不能直接编译,需要配置一下环境,没提供-Discrete point data management, the use of 4-tree management methods, for persons engaged in graphics algorithms or helpful. Rendering using OSG, can not be directly translated, need t
