[−][src]Function directx_math::XMQuaternionLn
pub fn XMQuaternionLn(Q: FXMVECTOR) -> FXMVECTOR
Computes the natural logarithm of a given unit quaternion.
Parameters
Q
Unit quaternion for which to calculate the natural logarithm. If Q
is not a unit quaternion, the returned
value is undefined.
Return value
Returns the natural logarithm 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.
