D3DMATRIX (D3D_OVERLOADS)

The D3D_OVERLOADS implementation of the D3DMATRIX structure implements a parentheses ("()") operator. This operator offers convenient access to values in the matrix for C++ programmers. Instead of having to refer to the structure members by name, C++ programmers can refer to them by row and column number and index these numbers, as needed.

typedef struct _D3DMATRIX {
#if (defined __cplusplus) && (defined D3D_OVERLOADS)
    union {
        struct {
#endif
 
            D3DVALUE        _11, _12, _13, _14;
            D3DVALUE        _21, _22, _23, _24;
            D3DVALUE        _31, _32, _33, _34;
            D3DVALUE        _41, _42, _43, _44;
 
#if (defined __cplusplus) && (defined D3D_OVERLOADS)
        };
        D3DVALUE m[4][4];
    };
    _D3DMATRIX() { }
 
    D3DVALUE& operator()(int iRow, int iColumn) { return m[iRow][iColumn]; }
    const D3DVALUE& operator()(int iRow, int iColumn) const { return m[iRow][iColumn]; }
#endif
} D3DMATRIX, *LPD3DMATRIX;
