D3DXMatrixRotationQuaternion Function

Builds a rotation matrix from a quaternion.

Syntax

D3DXMATRIX *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.

See D3DXQUATERNION to see how to calculate quaternion values from a pt (x,y,z) and an angle of rotation.
