ZW3D 二次开发-创建椭球体

使用中望3d用户函数 cvxPartEllipsoid 创建椭球体

函数定义：

    ZW_API_C evxErrors cvxPartEllipsoid(svxEllsoData *Ellso, int *idShape);
    typedef struct svxEllsoData
    {
        evxBoolType Combine; /**<@brief  combination method */
        svxPoint Center;     /**<@brief  sphere center point */
        double xLen;         /**<@brief  length of the ellipsoid along the x (mm) */
        double yLen;         /**<@brief  length of the ellipsoid along the y (mm) */
        double zLen;         /**<@brief  length of the ellipsoid along the z (mm) */

        int useAxis;  /**<@brief  flag to use axis (0 to use plane, 1 to us
