D3DXVec2TransformArray function (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Transforms an array (x, y, 0, 1) by a given matrix.
Syntax
D3DXVECTOR4* D3DXVec2TransformArray(
_Inout_ D3DXVECTOR4 *pOut,
_In_ UINT OutStride,
_In_ const D3DXVECTOR2 *pV,
_In_ UINT VStride,
_In_ const D3DXMATRIX *pM,
_In_ UINT n
);
Parameters
-
pOut [in, out]
-
Type: D3DXVECTOR4*
Pointer to the D3DXVECTOR4 structure that is the result of the operation.
-
OutStride [in]
-
Type: UINT
Stride between vectors in the output data stream.
-
pV [in]
-
Type: const D3DXVECTOR2*
Pointer to the source D3DXVECTOR2 structure.
-
VStride [in]
-
Type: UINT
Stride between vectors in the input data stream.
-
pM [in]
-
Type: const D3DXMATRIX*
Pointer to the source D3DXMATRIX structure.
-
n [in]
-
Type: UINT
Number of elements in the array.
Return value
Type: D3DXVECTOR4*
Pointer to a D3DXVECTOR4 structure that is the transformed array.
Remarks
This function transforms the array pV (x, y, 0, 1) by the matrix pM.
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec2Transform function can be used as a parameter for another function.
