D3DXQuaternionNormalize

Computes a unit length quaternion.

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

Parameters

pOut

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

pQ

[in] Pointer to the source D3DXQUATERNION structure.

Return Values

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.

Requirements

Header: Declared in D3dx9math.h.
