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.
