XMQuaternionConjugate function (directxmath.h)
Computes the conjugate of a quaternion.
Syntax
XMVECTOR XM_CALLCONV XMQuaternionConjugate(
[in] FXMVECTOR Q
) noexcept;
Parameters
[in] 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.
