D3DXQuaternionRotationYawPitchRoll

Builds a quaternion with the given yaw, pitch, and roll.

D3DXQUATERNION * D3DXQuaternionRotationYawPitchRoll(
  D3DXQUATERNION * pOut,
  FLOAT Yaw,
  FLOAT Pitch,
  FLOAT Roll
);

Parameters

pOut

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

Yaw

[in] Yaw around the y-axis, in radians.

Pitch

[in] Pitch around the x-axis, in radians.

Roll

[in] Roll around the z-axis, in radians.

Return Values

Pointer to a D3DXQUATERNION structure with the specified yaw, pitch, and roll.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXQuaternionRotationYawPitchRoll function can be used as a parameter for another function.

Use D3DXQuaternionNormalize for any quaternion input that is not already normalized.

Requirements

Header: Declared in D3dx9math.h.
