D3DXVec2TransformArray function

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.
