D3DXVec2TransformCoordArray Function


Transforms array (x, y, 0, 1) by a given matrix, and projects the result back into w = 1.

Syntax

D3DXVECTOR4 *WINAPI D3DXVec2TransformCoordArray(      

    D3DXVECTOR4* pOut,     UINT OutStride,     CONST D3DXVECTOR2* pV,     UINT VStride,     CONST D3DXMATRIX* pM,     UINT n );

Parameters

pOut
[in, out] Pointer to the D3DXVECTOR4 structure that is the result of the operation.
OutStride
[in] Stride between vectors in the output data stream.
pV
[in] Pointer to the source D3DXVECTOR2 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 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 D3DXVec2TransformCoordArray function can be used as a parameter for another function.
