D3DXVec3Transform Function

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

Syntax

D3DXVECTOR4 *WINAPI D3DXVec3Transform(      

    D3DXVECTOR4 *pOut,
    CONST D3DXVECTOR3 *pV,
    CONST D3DXMATRIX *pM
);

Parameters

pOut

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

pV

[in] Pointer to the source D3DXVECTOR3 structure.

pM

[in] Pointer to the source D3DXMATRIX structure.

Return Value

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.
