D3DXVec3TransformArray Function

Transforms array (x, y, z, 1) by a given matrix.

Syntax

D3DXVECTOR4 *WINAPI D3DXVec3TransformArray(      

    D3DXVECTOR4 *pOut,
    UINT OutStride,
    CONST D3DXVECTOR3* pV,
    UINT VStride,
    CONST D3DXMATRIX* pM,
    UINT n
);

Parameters

pOut

[in, out] Pointer to the D3DXVECTOR4 array that is the result of the operation.

OutStride

[in] Stride between vectors in the output data stream.

pV

[in] Pointer to the source D3DXVECTOR3 array.

VStride

[in] Stride between vectors in the input data stream.

pM

[in] Pointer to the source D3DXMATRIX structure.

n

[in] Number of elements in the array.

Return Value

Pointer to a D3DXVECTOR4 transformed array.

Remarks

This function transforms the array of vectors, 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 D3DXVec4TransformArray function can be used as a parameter for another function.
