D3DXMatrixRotationQuaternion
Microsoft DirectX 9.0 SDK Update (October 2004)

D3DXMatrixRotationQuaternion Function


Builds a rotation matrix from a quaternion.

Syntax

D3DXMATRIX *WINAPI D3DXMatrixRotationQuaternion(      

    D3DXMATRIX *pOut,     CONST D3DXQUATERNION *pQ );

Parameters

pOut
[in, out] Pointer to the D3DXMATRIX structure that is the result of the operation.
pQ
[in] Pointer to the source D3DXQUATERNION structure.

Return Value

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.
