D3DXVec3TransformCoordArray Function

Transforms array (x, y, z, 1) by a given matrix, and projects the result back into w = 1.

Syntax

D3DXVECTOR3 *WINAPI D3DXVec3TransformCoordArray(      

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

Parameters

pOut

[in, out] Pointer to the D3DXVECTOR3 structure 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 D3DXVECTOR3 structure that is the transformed vector.

Remarks

This function transforms the vector, pV (x, y, z, 1), by the matrix pM, projecting the result back into w=1.

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec3TransformCoord function can be used as a parameter for another function.
