WPF 3D 球面導覽

基於WPF的3D Sphere實現模式，升級實現了該3D導覽Demo。先pose一張demo效果圖

所有頂點的坐標來源於足球的頂點。足球整個球面完全由正五邊形和正六邊形拼成，每條拼縫的長度一致，故知道球體半徑后即可設法求出60個頂點的坐標。

       

具體求法屬於數學的立體幾何范疇，反正求解時廢了我蠻多精力的，完全是工匠精神支撐我求解完成，具體就不做詳述了，可參考以下圖：

得到所有定點坐標后，即可創建Viewport3D控件，並在坐標位置創建相應的ModelVisual3D對象。

我計算得到的60個點3維坐標：

private List<Point3D> GetBuckyBallPoints()

    List<Point3D> ltPoints = new List<Point3D>();
    ltPoints.Add(new Point3D(.850651, 0, 2.327438));
