D3DXVec4Transform function

Transforms a 4D vector by a given matrix.

Syntax


D3DXVECTOR4* D3DXVec4Transform(
  _Inout_       D3DXVECTOR4 *pOut,
  _In_    const D3DXVECTOR4 *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 D3DXVECTOR4*

Pointer to the source D3DXVECTOR4 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 4D vector.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec4Transform function can be used as a parameter for another function.
