Transforms a 2D vector by a given matrix, projecting the result back into w = 1.
Syntax
D3DXVECTOR2* D3DXVec2TransformCoord(
_Inout_ D3DXVECTOR2 *pOut,
_In_ const D3DXVECTOR2 *pV,
_In_ const D3DXMATRIX *pM
);
Parameters
-
pOut [in, out]
-
Type: D3DXVECTOR2*
Pointer to the D3DXVECTOR2 that is the result of the operation.
-
pV [in]
-
Type: const D3DXVECTOR2*
Pointer to the source D3DXVECTOR2 structure.
-
pM [in]
-
Type: const D3DXMATRIX*
Pointer to the source D3DXMATRIX structure.
Return value
Type: D3DXVECTOR2*
Pointer to a D3DXVECTOR2 structure that is the transformed vector.
Remarks
This function transforms the vector, pV (x, y, 0, 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 D3DXVec2TransformCoord function can be used as a parameter for another function.
