由于一个顶点只能有一条法线，所以你还要复制顶点。

Because one vertex can only have one normal, you must duplicate the vertices as well.

如图3所示，源物体圆锥被复制对齐到几何球体的多边面上，另一些方盒子则被复制对齐到几何球体的顶点上。

Fig. 03 shows, source object Cone copied and aligned to Geosphere's polygons and another object box copied and aligned with vertices of Geosphere.
