D3DXQuaternionNormalize

The D3DXQuaternionNormalize function returns the normal of the given quaternion.

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

Parameters

pOut

A pointer to the D3DXQUATERNION structure that is the result of the operation.

pQ

The pointer to the source D3DXQUATERNION structure.

Return Values

A pointer to a D3DXQUATERNION structure that is the normal of the given 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.
