D3DXVec3Transform function (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Transforms vector (x, y, z, 1) by a given matrix.
Syntax
D3DXVECTOR4* D3DXVec3Transform(
_Inout_ D3DXVECTOR4 *pOut,
_In_ const D3DXVECTOR3 *pV,
_In_ const D3DXMATRIX *pM
);
Parameters
-
pOut [in, out]
-
Type: D3DXVECTOR4*
Pointer to the D3DXVECTOR4 structure that is the result of the operation.
-
pV [in]
-
Type: const D3DXVECTOR3*
Pointer to the source D3DXVECTOR3 structure.
-
pM [in]
-
Type: const D3DXMATRIX*
Pointer to the source D3DXMATRIX structure.
Return value
Type: D3DXVECTOR4*
Pointer to a D3DXVECTOR4 structure that is the transformed vector.
Remarks
This function transforms the vector, pV (x, y, z, 1), by the matrix pM.
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec3Transform function can be used as a parameter for another function.
