C++结构数组初始化

Question

我有以下结构:

struct localframepos
{
    double ipos; //local room frame i(x) coordinate, in mm
    double cpos; //local room frame c(y) coordinate, in mm
    double rpos; //local room frame r(z) coordinate, in mm

    localframepos()
    {
        ipos = 0;
        cpos = 0;
        rpos = 0;
    }
    localframepos(double init_ipos, double init_cpos, double init_rpos) //init constructor
    {
        ipos = init_ipos;
        cpos = init_cpos;
        rpos = init_rpos;
    } 
};

如何获得以下功能:

localframepos positions[] = { {0, .5, .2},
                              {4.5, 4, .5} };

删除构造函数。要使用大括号初始化，类型必须是 POD。
