D3DXVec3TransformCoord Function


Transforms a 3-D vector by a given matrix, projecting the result back into w = 1.

Syntax

D3DXVECTOR3 *WINAPI D3DXVec3TransformCoord(      

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

Parameters

pOut
[in, out] Pointer to the D3DXVECTOR3 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 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.
