D3DXQuaternionNormalize function

Computes a unit length quaternion.

Syntax

D3DXQUATERNION* D3DXQuaternionNormalize(
  _Inout_       D3DXQUATERNION *pOut,
  _In_    const D3DXQUATERNION *pQ
);

Parameters

pOut [in, out]

Type: D3DXQUATERNION*

Pointer to the D3DXQUATERNION structure that is the result of the operation.

pQ [in]

Type: const D3DXQUATERNION*

Pointer to the source D3DXQUATERNION structure.

Return value

Type: D3DXQUATERNION*

Pointer to a D3DXQUATERNION structure that is the normal of the quaternion.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXQuaternionNormalize function can be used as a parameter for another function.
