D3DXMatrixRotationQuaternion function (D3dx9math.h)
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Builds a rotation matrix from a quaternion.
Syntax
D3DXMATRIX* D3DXMatrixRotationQuaternion(
_Inout_ D3DXMATRIX *pOut,
_In_ const D3DXQUATERNION *pQ
);
Parameters
-
pOut [in, out]
-
Type: D3DXMATRIX*
Pointer to the D3DXMATRIX structure that is the result of the operation.
-
pQ [in]
-
Type: const D3DXQUATERNION*
Pointer to the source D3DXQUATERNION structure.
Return value
Type: D3DXMATRIX*
Pointer to a D3DXMATRIX structure built from the source quaternion.
Remarks
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixRotationQuaternion function can be used as a parameter for another function.
For information about how to calculate quaternion values from a direction vector ( x, y, z ) and an angle of rotation, see D3DXQUATERNION.
