WPF 3D 球面导览

基于WPF的3D Sphere实现模式，升级实现了该3D导览Demo。先pose一张demo效果图

所有顶点的坐标来源于足球的顶点。足球整个球面完全由正五边形和正六边形拼成，每条拼缝的长度一致，故知道球体半径后即可设法求出60个顶点的坐标。

具体求法属于数学的立体几何范畴，反正求解时废了我蛮多精力的，完全是工匠精神支撑我求解完成，具体就不做详述了，可参考以下图：

得到所有定点坐标后，即可创建Viewport3D控件，并在坐标位置创建相应的ModelVisual3D对象。

我计算得到的60个点3维坐标：

private List<Point3D> GetBuckyBallPoints()
{
    List<Point3D> ltPoints = new List<Point3D>();
    ltPoints.Add(new Point3D(., , 2.327438));
    ltPoints.Add(new Point3D(., ., 2.327438));
    ltPoints.Add(new Point3D(-., ., 2.327438));
    ltPoints.Add(new Point3D(-., -., 2.327438));
    ltPoints.Add(new Point3D(., -., 2.327438));
