[−][src]Function directx_math::XMQuaternionConjugate
pub fn XMQuaternionConjugate(Q: FXMVECTOR) -> FXMVECTOR
Computes the conjugate of a quaternion.
Parameters
Q
The quaternion to conjugate.
Return value
Returns the conjugate of Q
.
Remarks
The DirectXMath quaternion functions use an XMVECTOR 4-vector to represent quaternions, where
the X
, Y
, and Z
components are the vector part and the W
component is the scalar part.
Given a quaternion (x
, y
, z
, w
), the XMQuaternionConjugate
function returns the
quaternion (-x
, -y
, -z
, w
).
Use the XMQuaternionNormalize
function for any quaternion input that is not already normalized.
